I have a clunk when I change gear and release clutch that I did not have before. Seems to be from the rear of the jeep. I put jeep up on jacks and when I turn the rear tire back and forth I hear clunk at rear of back driveshaft, and I can see driveshaft jumping around when I turn wheel back and forth. Am I missing anything?
Well the u joint is either shot or unbolted... unless there is so sort of damage to the shaft itself... Sold my A1 to a fellow while on leave might build me. Bolts front and rear are tight. Verify the 4WD shift lever is completely back. If u-bolts and joints are in good condition, no bent drive line, then check the differential. I'd disconnect the drive line, turn the wheels and listen and feel for anomaly's.
I had that sound and it was the rear a frame bushing. With engine not running, put it in gear, set park brake and push back and forth on jeep and see if that duplicates the sound.Sounds a whole lot like a U-Joint or loose bolts in the U-Joint to me. Can you shake or twist the driveshaft and see or hear anything in the U-Joint?
However, I had a sound like that and I had new U-joints on the drive shaft and the axle shafts and all the bolts were tight. I finally discovered the bolts holding the differential didn't have enough treads on them and even tho they felt tight, the rear-end was actually moving up and down a little bit when I shifted. 3 new bolts with full threads fixed that. this is for the one that is having the problem with the rear drive shaft. Did the universals been changed lately and is it possible that some of the needle bearings fell out in assembly. If so that would do it also.
Nope.. though this was a nos drive shaft and universal 6 years ago. Jeep doesn't go off road except hally once a year. Driveshaft is straight and bolts are tight and no clunk for 6 years. Anything I need to know to replace old one? I have nos universal spare Hard to install? TM9 is not clear how to remove snap rings and seals. Do I need to remove bearing race from yoke?
