i posted here the other day about a clicking noise i was hearing and i was getting a lot of vibration. narrowed it down to the u-joint on the front of the rear driveshaft. pulled the shaft out yesterday and went ahead and changed both u-joints on it. the jeep is running smoother than it ever has...EXCEPT the last 10 feet or so when i stop i get a horrible rumble that i think i coming from the rear. it wasnt doing it before the u-joint went bad so is it possible that the bad joints caused something else to get messed up? anything i can check? any help is much appreciated. cant afford a mechanic.:nonono:
