the others still had grease/bearings, the busted seal I did when I was trying to figure out if I had a bad one before I was schooled on the proper way to check for a bad u-joint..lol

 

I'm gonna check mine now, the vibration I've been having starts at about 55mph and get really bad at 60. Doesn't matter if accelerating or just running at highway speed, does it all the time. It shakes so hard it shakes the watch on my wrist. It makes the passenger side belt buckle vibrate against the b-post when not in use. I haven't taken it on the interstate yet to get it over 60, but i imagine it would be worse as it gets worse from 55-60. I think I will test them here shortly and if they are gone I will have the dealer replace them under the powertrain warranty.

By the way, how many miles were on that joint? I have 34,500 on mine
