Title: 91 318is loud thumping on deceleration
Post by: nofear3544 on March 09, 2008, 09:12:21 AM

Im getting a really loud thumping noise coming from what sounds like the front passenger side of my car. The noise appears when I do one of the following decelerate, brake, apply the clutch, turn right, or hit a large bump. The noise goes away when I give the car gas or drive at high speeds. I jacked up today and couldnt find anything noticeably wrong with the suspension. Please help

I've replaced my front bearings but I didn't have the symptoms your indicating.
Lift the front passenger side wheel off the ground .Grab the wheel at 12 and 6 oclock and try and move or shake it .If there is alot of play then your bearing may be shot.
My passenger side wheel bearing went at 191,000 miles but it would grind when I made a right hand turn.I replaced both .

i just had minake look at it cuz i dont have a lift.. anyway it was the driveshaft but it wasnt the guibo. it was the bracket that holds the rear of the shaft the rubber inside that bracket was bad and the shaft is hitting the metal.

the one defect of having a small car is that the driveshaft is hidden and requires alot to remove it.
