Author Message   Greg Posted on Wednesday, January 08, 2003 - 02:46 pm:    I have a '97 D1 w/95K mi, and recently replaced the u-joints on the rear drive shaft. I made scribe marks on the to help in re-installation, but after all of the handling the marks on the driveshaft were completely gone. I had no choice but to re-install the shaft the way it would fit best. Two questions: 1) Is there a special trick to replacing the ujoints? I mean, other than pressing them out and pressing the new ones in? No balancing or anything like that, etc.? 2)Is anything messed up by possibly re-installing the driveshaft differently than it was installed? Coincidently (I hope) my rover has developed a vibration today. Strangely, though, it is not constant. It SEEMS to occur when I hit a bump on the interstate at high speed, and the steering wheel begins to shake pretty badly, like something is wrong (not just a bad steering stabilizer). It also seems that the whole vehicle shimmies. I am about to replace the front ujoints, and maybe they are going bad with good timing. But, once again, the vibration is intermttant. Opinions/advice?   muskyman Posted on Wednesday, January 08, 2003 - 03:03 pm:    unless you seperated the splined slip joint the drivshaft shoud be fine. the bump induced shimmy/shake sounds like a panhard rod bushing to me   Bill Bettridge (Billb) Posted on Wednesday, January 08, 2003 - 03:16 pm:    Also - shimmy could be due swivel preload. Remove drag link and track rod at swivels and check preload with a fishing scale (or similar). Technically preload should be checked with no swivel seals in place, but I don't think anyone actually does that (big PITA unless the seals need replacing anyway) Bill   Greg Posted on Wednesday, January 08, 2003 - 03:29 pm:    Bill, I just replaced the seals in my hubs and swivel balls. What is preload? I simply disassembled hubs down to swivel balls, removed and cleaned CV joint, wiped inside of housing. I then disassembled further so I could replace the main swivel housing seal, and reassembled and replaced all hub seals. What did I not do correctly? Also, is the drag link and track rod the thing that is attached to the swivel housing by a tie rod end(s)? I did not disassemble those, I just worked around them. You can do that it appeared to me.
