I have a thump type noise in my bronco when I drive slowly over rough terrain. I was looking underneath and found that if I push up on the area where the two ujoints go into the rear of the transfer case the whole section moves up and down. It appears that there is a bushing or something worn in the rear of the transfer case. There is also something in between the two ujoints that allows some play, I think it might be called a cardon joint or something. The actual ujoints don't seem to have play but whatever it is between the two is allowing some. I can't quite tell what is in between the two joints. Have any of you repaired the two ujoints with whatever is in between and whats the deal with the rear of the transfer case, do I need a new bushing or bearing and seal??

I've done ujoints before but I haven't done the double cardan type. What is the thing in between the 2 joints, the manual doesn't show much but it looks like a spring or bushing that presses against both ujoints. I definately have something wrong in the tailshaft of the transfer case, there is alot of up and down play there. The manual just says it's a bushing and seal but doesn't show much else.

Oooh I love pictures.....OK when I push up on the cardan joint itself I have movement in the area of the centering ball, there is movement where the driveshaft goes into the rear of the transfer case and the whole transfer case moves up about an inch without too much trouble. The trans. mount looks ok but it does move up. How much give should there be in the mount? I'm definately replacing the ujoints but it looks like the play is due to the centering ball arae and the transfer case bushing if thats what it's called. There shouldn't be any slop where the flange comes out of the transfer case should there?

Any idea how involved this bushing replacement is? Can I do this in my garage without pulling the transfer case? It looks like it shouldn't be very hard.
