I totally agree. Your last paragraph is exactly why I needed to disengage the front. Coarse concrete (super grip), steep, and a curve at the top. I can't imagine the stress it would have put on the transfer case. I removed the front driveshaft, rear wheel only in LO, and all worked out great.labsy wrote:As long as you go uphill in 4LO only in STRAIGHT line, there is (theoretically) no additional stress to driveline, because all 4 wheels turn just about the same. This is especially (and practically) true in non-paved roads.
So if that's your situation, you can safely shift into 4LO and pull that rig in straight line uphill and nothing bad should happen.
Even more - in 4LO torque is evenly distributed 50/50 between front and rear diff, and so is also stress on driveshafts and particularly on U-joints. Which is even better than just rear drive.
On contrary, if that uphill is PAVED AND CURVED, I do not recommend driving in 4LO. Because steering left/right in 4LO presents a lot of stress to gears and shafts due to wheel speed difference in curve.
