MTGunner Posted September 30, 2019 Share Posted September 30, 2019 My 2000 Pathfinder is 4WD. Is the rear driveshaft a one piece shaft or two piece shaft. MTG Link to comment Share on other sites More sharing options...
XPLORx4 Posted September 30, 2019 Share Posted September 30, 2019 It’s 3 pieces. Slip yoke, main shaft, and pinion yoke. 2 Link to comment Share on other sites More sharing options...
MTGunner Posted September 30, 2019 Author Share Posted September 30, 2019 There is a vibration that needs to be isolated. Thanks. MTG Link to comment Share on other sites More sharing options...
mjotrainbrain Posted October 1, 2019 Share Posted October 1, 2019 The only moving pieces on it should be the U-joints and slip joint, realistically the only part that should wear on it would be the U-joints which should be easy to check. It is not a "2-piece" style with the carrier bearing, that was only for the 2wd's I believe. Link to comment Share on other sites More sharing options...
XPLORx4 Posted October 1, 2019 Share Posted October 1, 2019 What are the conditions under which the vibration occurs? Vibration could be caused by worn U-joints. It could also be caused by the slip yoke not being sufficiently engaged with the splines of the output shaft. This would be more likely with a large suspension lift. It's not too hard to remove the rear driveshaft. Before you do, wiggle the front of the driveshaft near the slip yoke. If there's a lot of play, that could indicate the slip yoke needs to be slid over the output shaft more fully. You'd need to lengthen the driveshaft or somehow make a pinion yoke driveshaft spacer to fix it. Check for worn U-joints by rotating the driveshaft and watching for slop in the U-joints. To remove the driveshaft, remove 4 17mm nuts/bolts holding the driveshaft to the pinion yoke on the rear differential. Once the driveshaft is free from the pinion yoke, you should be able to easily slide it out of the transfer case. 1 Link to comment Share on other sites More sharing options...
MTGunner Posted October 3, 2019 Author Share Posted October 3, 2019 My 2000 Pathfinder has no lift. It is stock height. Will check the u joints. Vibration and noise increases with speed. MTG Link to comment Share on other sites More sharing options...
Riderman Posted October 3, 2019 Share Posted October 3, 2019 I had the same issue. One of my rear driveshaft pinion yokes was bad. The driveshaft shop cut off and replaced the yoke, and balanced the shaft for $80.00 Link to comment Share on other sites More sharing options...
