RE: Semi floater,full floating rear axel.

snip..... Play the lotto, you have a better chance of hitting than seeing a C-clip axle break under normal use A VERY good analogy !!!! :B :B :B :B :B :B You are so right...there are folks who do win the Lottery.... :C It's about the same chances is my guess...so agree with your analogy :C

RE: Semi floater,full floating rear axel.

In 30 years as a Ford tech I've never seen a C clip axle break in normal use, drag racing, yes. Most who drag race use C clip eliminators. http://www.summitracing.com/search/part-type/c-clip-eliminator-kits Absolutism... Just because you haven't does it mean it doesn't happen... Opposite, is if I say since I've seen several since I started driving in 1963, does it mean everyone will have it happen... Mud hen vehicles NOT boulevard dragging. None that I've seen were towing either. Most were 'cars' and one a pickup Just take your position and the links...if that kind of usage is known to break them...how close to that kind of loading is on semi's towing heavy? Another analogy is folks saying it does well and lives in racing...therefore should hold up towing heavy... Do take that track vehicle and then hook up several tons to it's tail and then see how long it will last tugging that out on the street

RE: 2015 Expedition - Happy with Ecoboost 365HP + 420TQ!

Bruce....yes, interesting and love this stuff too NOx is going to be managed with bigger CATs and there are new sensors that will come along with that evolution Particulate, for now, looks like diesel like exhaust filters and the onerous cleaning/purging cycle(s), but the latest in this embryonic technology looks like the shape of the piston top. It is looking more and more like a bowl than a flat top. DEEP bow with a flatter head CC area. Controversy over flat or protruding into the piston bowl cavity or ??? The torque curves looks much like a big block gasser and diesel Top RPM won't reach small block gassers at this point, but who knows what these kids in their labs will come up with No throttle...just like diesel. Forced fed is amazingly doable. Back on this topic's IP...direct injection of gasoline... Now that the injectors are 'FAST ENOUGH', multiple squirts of varying duration (control the burn from very rich...to extremely lean) Much work is being done with the nozzles. Ruby is the leading material BUT...with pressures above the diesel common rail...Bosch CP4 pump issues are going to come up...but they are now aware of the stupidity in design from those Bosch engineering teams...a better pump will come and betcha a CP4 for diesel will morph from this work So similar to the GDICI work and are now married. We will see it in the next gen DI gassers...ruby orifices...IMHO Finally, pre-chambers are also coming from GDICI into current DI to most likely become next gen DI Yes, fun stuff...

RE: Semi floater,full floating rear axel.

Yes, on the newer rear axles with disc brakes...the disc will then be held in place by the caliper...which it is *NOT* designed to do. Nor would it be convenient to experience during a trip... This is where ALL of those forces from the inside radius pavement/tire/wheel/axle is focused http://img.photobucket.com/albums/v77/bentoy/Towing/C-Clip1ab.jpg~original width=640
BenK 10/19/14 10:36pm Tow Vehicles
RE: Semi floater,full floating rear axel.

Think about this during a high speed turn...all that is keeping the inside radius tire/wheel on is the C-Clip Think about how much area is in contact to hold all that force from cornering...all that force is on the grove to C-Clip in these pic's https://sp.yimg.com/ib/th?id=HN.607994041739051839&pid=15.1&H=120&W=160&P=0 width=640 http://image.fourwheeler.com/f/8519761+w600+cr1/0112or_axle07_zoom.jpg width=640 That is about 1/16" or maybe 1/8" on the C-Clip. Not full circle either, as the C-Clip has an open area to allow it to slide onto the axle Lucky that it does NOT have differential RPMs between those mating surfaces Just the traction pulling the tire/wheel...therefore the axle against the C-Clip. How much force do you think there is?

RE: Semi floater,full floating rear axel.

Rhetorical, know the answer...why did they 'need' to tack weld the C-Clip? Because it is a weak link of any Semi that has a C-Clip design Hot Rodding around back in my teens...was sitting in the back seat cruising the local boulevard....dragging from stop light to stop light... GTO was buddies who I helped build... Beating up other buddies rides that I also helped build... My ride was the family's second station wagon...a pink 1954 Ford...not 'my' car, but the families and dad won't let me hop it up...you guys should understand trying to get a date with my pink Ford vs the other guys and their Mustangs (no Camaro's yet), GTO's and Vettes...so rode with them most of the time... Noticed a wheel poking out on my side (passengers) and it had a rod connected to it...that seems to be part of the GTO I was in... Lucky, as the other guys honked and pulled over... Busted C-Clip and very common among rodders. I've changed out many in my teens and they were mangled and/or worn thin so that they either busted or mangled enough to come out without taking out the axle keeper rod Side loading that tapered bearings solve. Have to understand by Timken invented tapered roller bearings...thrust loads that a straight roller bearing does not manage Just this year...have come across two vehicles (cars) on the side of the road with their wheel/axle out about 3 feet. Freeway exit ramps, so no time to take my cell phone out for a pic...other was on the side of the freeway so again no time to take out the cell...

RE: Semi floater,full floating rear axel.

Didn't know there are tapered bearings for a semi floater, but now that I've seen it myself know the why a C-Clip won't work there Tapered bearings require a pre-load. Lots of pre-load that would wear out a C-Clip in a hurry. That is the main failure mechanism of C-Clips...wearing out to allow it to move out of the captive counter sink in the carrier So for a tapered bearing semi-floater, it has to be much more solid tan a C-Clip With the higher pre-load...make sure to flush your diff fluid on schedule. Use the severe duty schedule when towing heavy

RE: Are You Buying All These Half-ton Claims?

X3 So many consume their OEM's design margins and never understand...because today many/most do NOT keep their vehicles long enough to suffer the consequences of their actions...consuming the OEM's designed in margins Why then do most understand buying used has the risk of getting one from someone who either consumed most to all of the design margins and/or did not maintain it well?

RE: 17" Load Index 126 tires

Pushing the limits of this class of tire, "LT" Since pushing this class limit, better solution is to move up to the next class, commercial class NOTE that they also weigh much more and cost much more

RE: 2015 Expedition - Happy with Ecoboost 365HP + 420TQ!

It all boils down to just a few things and the stuff most folks talk about are not them..except for buddy #1 is PSI on the piston tops times the area of that piston top #2 is the amount of energy in the fuel #3 are all of the characteristics of the laws of physics that play with #1 & #2 Boy Racers & gear heads have known that since the advent of a hot rodding The small displacement EcoBoost is forced fed enough air to fill a NA big block, so it behaves similar to a big block. That is #3 stuff, as are most of the stuff below Getting the fuel/air mixture to burn (not explode like most think) has rapidly expanding gases inside a container...AKA the cylinder/ head/piston top. The hotter you can get it, the more expansion potential there will be. Meaning more PSI 'potential' Ignite it before TDC and now you have it expanding in a reducing volume container. That further increases PSI. This is where one of the biggest ills comes into play...pre-ignition, or ping, or detonation That PSI's affect is factored by the piston top area, the crank offset (throw), etc Must add right now, that the piston/rod/crank offset are traveling at about the speed of sound (IIRC 752 MPH at sea level and normalized humidity and temp). That, that mass is REVERSED in an instant to accelerate back to approx the speed of sound. Repeated XX to over XXX times a second. This is part of what is known as pumping losses There is a HUGE friction potential and the why of using the best engine oil you can....plus how it is broken in (the hills and valleys of the cylinder wall for oil filming) Ford chose small displacement for MPG and power via forced feeding. This is what ib516 means managed by the right foot...the ECU's sensors, sense rate of change, ultimate stroke, etc GM chose large displacement for power and variable displacement for MPG. The ECU manages the variable displacement based on feedback from the other computers on board...all keyed or taking their master input from the right foot. Now to 8iron's....yes all ICE's work the same and the modifiers (variables) makes the difference On this, know that ICE's most efficient architecture is a 2 cycle diesel At about 40% efficiency. The rest of the energy is lost in pumping losses and rejected HEAT The high MPG of hybrids are due to two things. Two sources of power, the liquid fuel (gasoline or diesel....toss in propane and the other forms of liquefied gaseous fuel) and the battery...which has a higher power density than either gasoline or diesel False MPG, as the day of reckoning is the day you have to replace the worn out Li-Ion battery. Tens of thousands of bucks at todays current cost structure The same can be said for 100% electric too. Plus using the grid to recharge skirts the various road taxes...for now This thread is about the Ford architecture. I'm not a fan of small displacement ICE's for towing. Especially heavy. Prefer a larger displacement ICE (why I have a big block GMT400) for towing heavy. My 2 seater is 2.4L OEM and have a 'built' ICE on the engine stand. Hogged out block, stroked via diesel crank and a worked head to be about 3.1L inline 6. The 2 seater before this one had a 1.8L inline 4. So I also understand small displacement. Plus I'm a GM fan, but an NOT blindly loyal The next gen ICE after the above Ford and GM offerings will be GDICI, which will have even better efficienies

RE: Semi floater,full floating rear axel.

For those who haven't worked on one, or doesn't know what a semi with a C-Clip holding the axle on...here are a few pic's Here is a typical C-Clip and the axle end with the grove for the C-Clip. The C-Clip is inside the diff pumpkin housing https://sp.yimg.com/ib/th?id=HN.607994041739051839&pid=15.1&H=120&W=160&P=0 width=640 This pic is of a C-Clip that has failed and the axle is running out of the axle tube. *ONE* bearing on these and it's outboard by the brake flange/backing plate. Not towing, so if towing...it would have much higher loads and stresses on the rear axle http://1.bp.blogspot.com/_cPOoKn1sLvk/SMhaHH-ioGI/AAAAAAAAAkY/U91trC8D8UQ/s400/c-clip-axle-fail.jpg width=640 Here is how it looks like when working on one.

RE: Are You Buying All These Half-ton Claims?

Which half ton are you all talking about? Marketing badging is just that...Marketing...NOT specifications These are all 'half ton' GVWR's and the best way to refer to any TV is with their specifications (GVWR, GAWR, GCWR)...which many already do when they need/want to be more specific or clearer on the topic My Silverado is a C10 with the "HD" package (Big Ten marketing nomenclature back then) and has a GVWR of 6,200 "half ton" GVWRs: 6,2007,2007,4007,6008,200Did I miss any? They also come with these marketing nomenclatures: Heavy DutyHDMax TowBig TenDid I miss any here? If these would help sell to the 'half ton' crowd: Super Duper, Extreme Tow Package, Best in class (yes, it is the only one in that class), King of the Hill, Mike Row package, NY Mets Special, etc, etc... Oh, don't forget the number of lug nuts...but then this Ram 2500, 3/4 ton with a FIVE lug wheel setup is less than the current 'half ton' with SIX lug nuts...oh...there is a HD half ton with SEVEN lug nuts...which half ton are you guys talking about again? Betcha it's GVWR hasn't changed, and that the 'new' or 'current' RAM 2500's GVWR is in the +8K GVWR http://img.photobucket.com/albums/v77/bentoy/Towing/2014-10-88-22-18.jpg~original width=640

RE: GM Silverada Beats F250 In Frame Twist Test

Only matters to those who take their trucks/SUVs off road Pavement folks should have no problems, as that is the fat part of their customer based bell curve Only at the extreme end of that bell curve would have this type of issue on a 'regular' basis Question is how often does a pavement queen get into this condition out on a parking lot...launching a boat...etc ?

RE: White knuckles for 600 miles!

'Sidewall stiffness' has many, many other attributes PSI is one Ply rating or load rating is another Aspect ratio is yet another Rim width vs tire section width too. This plays with the sidewall bendback I talk about all the time. Construction (design, production and materials) also plays Suspension. Shocks, wheel offset, caster, spring rate curve, etc. The best handling and quickest response times of a tire is lost on a mud hen suspension setup for 'ride quality' All are in consideration to the designers, along with mandated codes/specifications/etc from regulatory agencies Then the characteristics of the above combo's offered for sale Ride quality creeps in too often for my taste in driving and is NOT on my 'have to have' list. At the bottom of my 'nice to have' list Slip angle is often mentioned in my car magazines, but not often on towing forums Not just slip angle, but the response times thereof. I call it TT (toss and tuck) from my racing days. Often referred to as 'responsiveness' of that tire For this thread and OP, take PSI Each end of the vehicle has different duties. From weight carrying to steering (yes, even the rear's fixed steers...holds straight...to a point) The exact same tire/wheel, but with different PSIs will have differing slip angle, acceleration/braking characteristics, response times, ETC The why of keeping the tires for each axle the same, within some tolerance The rear tires deal with another issue and that is the push from any trailer (Fiver and tongued). They must continue to steer straight to the TV's centerline pointing...with some slip angle due to those forces To the OP...make sure your four corners of tires are aired up to spec. That each axle's tires are within a small differential Apologize, thought you had a Sub, but now read that you have a GMT800 2500HD pickup. It does have a better receiver than GMT800 SUV's, but are of the same design. I still recommend replacing it with a traditional designed receiver.

RE: White knuckles for 600 miles!

PS...digital tire PSI gauges have a RICH history of not reading correctly. Depends what brand/model and how much you paid...that is what I've been reading up on a potential purchase. Sticking with all of my pencil gauges and one dial gauge (not digital)

RE: White knuckles for 600 miles!

Understand the basics and the 'goal' of the setup...the orientation is to have the TV return the front loaded weight to +/- static/unloaded height/weight...check your manual on this, as they are all different these days Tongue weight (actual) should be 13% to 15% levelness of the trailer should be level at it's highest pointing and I prefer slightly down...that has solved many others problems with that alone Of course since towing heavy, the tires should be aired up. Rear of any Sub should be at max listed on tires sidewalls Front has room for less, a most all weight on any Sub is behind the drivers rear door edge, so on the rear axle Betcha you still have the OEM receiver on your GMT800 Sub. That is probably the first thing you should check. If you bought used, hope the previous owner switched it out to a traditional design. The OEM design is dangerous. About $200 bucks for a traditional designed from after market providers. Plus about 1 hours labor to remove/install. This one is the biggest problem with GMT800's

RE: May not want to swap tire sizes on that Ram just yet..

The most accurate OEM dash gauge is the speedometer. They don't want their speedo's to a reason for the LEO's to pull you over More than TPS & ABS computer needing to know, but the torque management for the whole setup and the +5 speed automatic. Toss in traction control and anti-sway if you have it. Maybe more computers are involved. Anyone know if the tuners also change those functions, other than just the speedo? PS...the computers count "rev's per mile" to calculate everything and the tire's OD is just what we are told
