clunky noise over bumps

Hotelbldr · 06-11-2001, 08:39 PM

After rebuilding the front end with all new parts. When the car travels overs certain types of bumpy roadways it makes clunky rattles from the front end. Sounds like every thing is loose (which it isn't, its all been checked for proper alignment and even after 1 1/2 years its still perfect). The body parts have all been checked for snug bolts. Is this the norm for these cars or do I have a ghost loose up front?

I guess it could be a million things but I had that same thing happen and it ended up being the battery. Wasn't strapped down very good. Don't mean to insult your intelligence or anything but I don't know too much about the suspension.

Steering box

or

Coil spring perch's

in December I replace both lower control arms and now mine is doing about the same as yours. I got under the right front and pushed and pulled up and down on the car using the bumper and could get it to make the noise. I think mine is the lower control arm. If I hold my hand on it at the same time I move the car up and down I can feel it while it makes the sound. Also if the upper control arm nuts are too tight you will get noise like that. Let us know if you resolve the problem and I will do the same.

One more thing to check. Replace those old engine and tranny mounts. A bad tranny mount gave me a bang on right hand turns.

Check the shocks and ball joints, upper and lower). That's where I would look first.
