I can personally attest to this fact. I thrashed mine on the trail this weekend and despite dragging pretty much everything underneath the truck and beating the body up the 80 was amazing in the hills. May want to think about protecting that t-case though. I believe its cast aluminum.
I threw a way what was probably a good T-case/center diff.
My rear drive shaft yoke was plugged and I (not knowing what I was doing) kept adding more grease to the yoke (i was wondering where the grease went). When I took the drive shaft off I had to remove the zirk and all the grease shot out (I still was clueless). Then when driving the viscus coupler would lock up. After driving 70 mi at 70 mph the T-case/center diff got so hot that it took several hours for it to cool down enough to unlock the viscus coupler. I finally took the garden hose to it and the water cooled it down. Thinking it was a bad bearing and that it had 210,000+ mi on it, I replaced the t-case.
UPS dropped the NEW T-case, had to have another one sent to me. The bolts on the flange were pushed in and wee stuck on the case.
Less than a year later the T-case started a leak at the split of the case, Toyota gave me a new one.
That plugged yoke cost me $2000 and lots of (me) labor.
I am sure that the T-case was not damaged as when I took it apart it looked fine, live and learn.
