    Question Universal Joint Part Check

    Is the Napa part # P369 the correct universal joint( front axle drivers side) for my 1999 Cherokee. This is what I was given at the store. The references I have found seem to indicate that this is a drive shaft U joint. It has a grease fitting if that makes a difference. Thanks in advance.

    If it came with a C clip it is a drive shaft u joint. Axle u joints do not have a C clip

    Returned joint. Turns out they didn't have the correct one. So I guess he gave me whatever he had. I should have known better then to trust him. When I asked him if he knew way to work around my 150 ft/lb. torque wrench for axle nut. He told me to use 150 lbs. till click then reset it for 25 lbs. more. and continue tightening. I guess I have that look.

    I have always just used my impact wrench on those. Once you get up to those numbers on hardened alloy steel, 25# doesn't make that much difference.

    Job finished.During road test and later driving I'm picking up vibrations that feel like rumble strips,through all driving speeds. Vibration is present even when I'm coasting with my engine off. The u joint was flexible when I put it on I did break my torque wrench trying to go to 150 max. not sure what axle nut is torqued to.Torque wrench will only work in reverse now. and 4 ft. 4" pvc pipe shattered. Before u joint change there was just clanking and visual inspection during break inspection. By the way I didn't find a single bearing in the entire u joint.

    How were those unit bearings? T/he rumble is typical when they start to go

    The hub. Did you check them by rotating them to see if they rotated smoothly?

    You replaced the axle u-joints, not the drive shaft joints, right? Reason I ask is that I changed d/s joints on my dad's truck about 10 years ago and accidentally put the d/s back in backwards and got vibes like that. Impossible to do on our XJs since we have slip yokes, but I suppose your front shaft could be reversed accidentally.

    The shaft came apart from the hub,when i was fixing u joint which was a surprise.I didn't know they were separate Can it really be put in backwards? I jacked up car again,held wheel at 12 and 6 and shook it. It did have a little play. The other side same thing. This rumble strip vibration seem to start soon after I changed u joint which looks good. and I'm very proud of. Thanks to the good people on this forum. Is it possible to put axle back on hub backwards?
