Guys, I'm on my second set of ujoints, but I'm putting new ones on and all the ball joints are being done tomorrow along with lubing the end shafts. Apparently the bearings are ok...and I have a hard 210,000km on mine. No vibration except for the shot drivers side ujoint. I had my shafts all rebalanced and replaced all my ujoints except the fronts.... I expect another 210,000km on the new ones. I put MOOG's on the bottom, stock on top and Spicer original ujoints. ks
