sudden drivetrain vibe

[goldtooth]

driving to the junkyard sat morning and going over the hill was a little icy and the jeep was spining and sliding a little going up. it would spin a little on the icy sections and then catch the dry and go up. i then tried to put it into 4hi but it wouldn't go. tried about 4 times and it would grind a little but mostly just not move, even around 15mph. i left it alone and just delt with the ice. when it cleared and it tried to speed up, i was getting these bad vibes around 1500-2000 rpms and the whole jeep feels funny. i made sure it was not stuck in 4wd as the front dline spins free. any ideas on what happened or what i should look at? rear driveline? shot tcase?

thanks

check the u-joints first, might be worn out

would have to agree with jp thng when was the last time they were service/lube try to keep them lube around the oil change and what time of lube do you use for the joints i use a marine grade

yeah, i was going to check the dline when i did the 8.8 swap. seems weird they would go suddenly like that. maybe the sudden no traction/ traction thing did them in.

took the driveline out tonight and the rear ujoint was toast. one of the bearing caps was full of metal dust :eek: no lube in that one. the rest were fine. gonna replace both sides tomorrow.

it also seems like my yoke on my tcase has more play on the splines than i think it should. might do that sye sooner than i thought.

new ujoints in, vibes are gone.

the truck just seems to drive better now, smoother.

thanks
