I recently had some serious problems when fourwheeling with my 95 Tahoe (6" Pro Comp lift, 35" tires). When the suspension was in full articulation there was a whole lot of binding in the drivetrain and the truck was hardly driveable anymore. Eventually I broke the steering knuckle, too.
Recently, after everything was repaired, I changed the tires and while doing this I experienced a strange phenomenon: Raising the front of the vehicle, the suspension flexes out and eventually the tire leaves ground. I learned that I could not fully turn this tire anymore. There was something blocking the movement that must be located in the front differential, I believe. I can turn the tire until it hits that obstacle, which is about a quarter of a full turn. 4WD was turned off.
I investigated the problem a bit. The front left tire can be turned fully at any given flex rate.. Then I tried the rigth tire again with a jackstand and a jack and I learned that the obstacle would only occur from a certain amount of flex on, i.e. when the suspension is flexed out quite a lot. Before that the tire would move freely just like the left side tire does at any flex rate.
I am wondering if this is a problem or if it is simply normal with the GM IFS difs. Does anybody know? Maybe one of you guys could just try whether you can turn your right front wheel when you lift this side of the truck by a jack under the frame? I am a bit suspicious that this my have caused my fourwheeling problem and want to take the truck to the dealer. However here in Germany they are not really experienced with Chevy trucks and therefore I need to know for sure, first.
Thanks a lot.
