Howdy,
Replaced all 3 U-joints in hopes of eliminating that annoying whine from the driveline. The center U-joint was really rusted in one of the bearing cups and the "clunk" has been eliminated.
However - I now have driveline vibration from about 2000 - 2500RPM. Everything was indexed properly before removing the driveshaft and I indexed the configuration between both parts of the driveshaft before replacing each U-Joint.
The new u-joints have grease fittings and the old ones did not. Could this be the cause of the vibration? Maybe the weight of the grease fittings is enough to throw the driveshaft out of balance?? Do I have a shop re-balance the driveshaft?? Or, the other option is to buy new u-joints without grease fittings and do it all over again, which thrills me to no end.
Any assistance is much appreciated....
