had it checked out, all was fine. BUT the ford stealership FAILED to notice that my pitman arm nut was about to fall off!!!!! I noticed that after they did their thing and I drove it home. Made them beat it to the proepr torque. I added a second nut to act as a jamb nut, painted white lines on it so I can easily tell if if comes loose again. Stupid friking idiots at Ford. Possibly the cause of the original problem, but who knows.
could be 16's, I am at work and did not confirm. thanks for the correction. What a difference an inch makes ;) and thanks to MOD for moving this to the correct category. getting some great feed back on where this thing is gonna cost me $. it is never "oh, you just needed more air in your tire, or your tool box shifted..." more like "oh, you need a custom made diamond studded titanium muffler berring"
cyber fixin? is that asking others for similar experiences to help identify areas of potential causation, or smashing my PC on the hood...
The diesel folks are coming up with the same scenarios, so everyone is on point! thanks to those who replied so far. I have an apt with a good suspension shop tomorrow and will do the brakes this weekend.
thanks all, I don't think the lift is 100% the issue as we have towed for 7 years with it over the same route. Although I am sure it is not completely innocent... I will get the front end looked at soon.
Keep your thoughts a commin' all great input on where to look
01 F250, 6" lifted 4x2, auto, Crew Cab, Short Bed, 7.3L Diesel, rear air bags, 33" tires 15" rims, teconsia brake controlelr, while towing our 29' 10K lb 5th wheel in the moutains on a freeway, slight down hill, slight gentle left hand turn, new pavement quite smooth, at about 35-40mph in a 45mph zone, gently/moderately applying brakes I got a unjulation in the whole truck. Felt like I had roger rabbit cartoon tundra tires that were flat on the front end, the truck bucked/lunged to the front left wheel which was on the outside of the gentle turn, then rocked back left, and repeated for say 4 seconds back and forth until I got it to say 10mph and pulled over. the steering wheel turned back and forth quite a bit (more than the usual slope), so I had to fight it a bit. pulled over, everything looked good in the suspension and wheel bering areas, checked wheel lug nut torque and they were fine, tire pressure is fine, front pads looked fine. We limped home with no isuses.
I can't figure what failed or went wrong. my only guess is the trailer brakes did not kick in and the rig pushed my truck slightly sideways as we were turned at a 15-25 degree angle to make the turn, kind of rolling the side walls of the tire. any ideas? (let me know if this is too off point and I will move it to the towing forum)
