While visiting a local hilly campground I had finished my visit and was heading to the clean out. The location of the cleanout was up a steep incline and around a bend on pavement. I had to decide to pull in 2HI and strain my transmission or choose 4LOW and risk damaging my front axle. Who else thinks trucks should offer 2 wheel drive low range as a option??

That wouldn't really solve the problem because 2WD with a locked rear axle would scrub too. Less, for sure, but it still would.

I remember years ago that was an option. I had an 84 3500 SRW with a 6.2L in it. There were times when I needed the lower gear ration, not necessarily 4 X4 low. I could just not lock in the front hubs and have access to the lower gear ratio without being in 4X4. However now days with all the power these newer pickups have I don't think it is necessary.

Nothing said aboot a locked rear end!!! Shouldn't enter into the equation!

OP, welcome to forum!!! What are driving?? Don't see anything in your profile. If a Ford, and have the auto vacuum hubs, there is a modification that can be done to engage 4W lo without the hubs activating. There may be something like that for other mfgs system, I don't know.

If you really feel the need for 2wd low you could always have a divorced transfer case installed. Plan on spending a few $$$ though.

Sorry I drive a 2005 Sierra 2500HD. Pulls great but still has its limitations. I just really hate the feel of turning in 4WD. I swear something will snap if you turn to hard. Reading different articles about low range where they say to use it for off road and towing heavy loads. But if you can't steer what good is it. Going to find out more about this. I have a small tractor that offers hi and low range in 2 and 4 wheel drive. For a little tractor you can move lots in 2low without the binding.

I have a Ford with the auto vac hubs, and would like to hear more about this mod. Could you post a link, or give a brief description of this mod? I understand that pulling off vac line would work, but an easy mod kit would be great.

There have been many vehicles that could be put in 2LO. AFAIK, it has always been recommended against by the manufacturers, because of the excessive torque that could be applied to the rear driveshaft and axle shafts.
The driveshaft and/or axles shafts could be twisted it two.
Yes, it can happen. I have seen the results in trucks and electric forklifts (lesson learned: NEVER use reverse to stop when the brakes fail. That 2 inch axle shaft WILL twist in two!)
