After a bit of wheeling at the weekend the center diff seems to have failed on my 2001 UZJ100. I noticed while turning round on a car park at the beginning of the week the transmission was binding up and then it would give a bang that shook the car! I checked the centre diff actuator out and worked the lock gear by hand but that is fine. So then I disconnected the front drive shaft and with the transfer in neutral and the center diff unlocked I can turn the shaft almost a full turn and then it binds. I can force it past that point with a bar and repeat.
I've left the front drive shaft off and am driving with the center diff locked while I wait for a replacement transfer box to be delivered next week. Once I have them swapped over I'll strip this one to see exactly what's busted but I'm expecting either the pinion or side gears are damaged.
At the moment I'm putting it down to crossing some logs on a man made obstacle (positioned to catch both axles at once etc) with the centre diff unlocked, letting the traction control do its thing and ending up rocking back and forth a few times quite violently as the ATRAC tried to make it's mind up what to do (I'm used to a fully locked 80 and was experimenting!). That and the added gearing of 36" tyres must have been too much for it. I guess in future I should make sure the centre diff is locked before I push it but this is definately a bit of a let down after being used to an 80 and not breaking stuff so easily.
Any signs of 100's being prone to weak transfer box center diffs?
