Got the Ujoints from Rock Auto today. Now time for bloody knuckles and cursing this weekend! My original set made it to 70k, so it sounds like I have made out better than many of you guys (although it probably needed them 10k ago...) Can the bearings be repacked at this time, or are there seals that need to be replaced I suppose? Or sealed unit? I've got a needle fitting for the end of my grease gun that I haven't put to use yet...
