1992 FSB. I am sure the U-joints are needing changed but am worried it is more. I have a bad vibration while driving at any speed but when I shift to neutral it stops even while coasting. Does this sound like just U-joints or could it be other? Nothing has changed since this has started as I have checked weights on driveshaft, tires balanced, trans shifts fine with no problems. Only other thing is the infamous clunk while shifting to reverse from stop. Hoping this is all to blame on u-joints but if anyone has had this problem and found it to be more I may have to wait to start chasing the problem due to money being short. THanks for any and all responses. If more info needed please advise.
