Clunk,clunk in CJ 4 lo?

Ok never mind, I climbed under and rattled front driveshaft, so that answers that question. Funny a freind just bought a YJ last month, I climbed under and saw his front drive shaft U joint with no caps left, so helped him replace them, then my daughter comes home and said her tranny is making a humming noise, I climbed under and saw no caps left in her driveshaft, this was a 1 year old D. cardon, supposedly sealed universals, no grease fitting, anyway it must be that time of year or something.

Glad you found the problem but while you're under there check your tranny mount. After 25 years of heat and leaked oil it is probably ready to come apart. The first thing I thought of when you described the noise was that your mount had broken loose and allowed the tranny tail to slide over enough to allow the rear U-joint in the front shaft to hit the tranny tunnel.

Don't you just 'love' those POS 'lifetime' sealed u-joints?

When I am in full wheeling mode, I only get about 8 months out of them, maybe a year. I went back to the cheaper greaseable ones. No more issues.

Canadian Tire took all 7 that I could find receipts for back.

Not many parts left on my CJ that haven't been changed, including tranny and mounts, but thanks anyway, glad it was Ujoint and not t case.

Last time I bought them was for my back ones, Can tire had greasable for $20.00 or non greasable for $25.00, figured I'd splurge and buy the non. Daughter just got a job at a local parts store, greasable is $15.00 my cost, so I'll buy them there, get 3 for less then 2 at can tire, have one for spare, since I just put my last spare in her jeep.
