Knocking/Thumping

Hi all,

My 95 SL2 has a knocking and thumping sound from the right side, whenever
the car moves. Can't hear it on the highways, but even rolling in neutral on
a smooth road makes the same noise. I don't see what it could be, checked
the things in the trunk, had a broken bracket fixed on the exhaust, and it
was checked to be okay, perhaps loose quarter panel? Coil springs moving
around?

Any input would be appreciated.

Thanks.

 

Could be the tie rod ends are worn out. Just had the right side
replaced a few months ago on my wife's 97. It made a knocking sound
when going down the driveway almost like a motor mount was loose. It
was not noticeable on the roads at most speeds.

Rythmic? Varies with wheel speed? Check the brakes, and the brake hose
to the noisy wheel. Had a wagon that did it forever until we replaced a
somewhat clogged hose..

 

Is it from the front or the back or you aren't sure? You seem to be
looking at things on the back, but it sounds like a CV joint. If it doesn't
happen at highway speeds, it may be because drivers don't normally make
anything but the gentlest turns at high speeds... and CV joint noises
are normally first noticed when the steering wheel is turned.

Thanks for the replies, I will take it in to Saturn next week, as it sounds
it could be anything. The noise is random, sometimes don't hear it at all,
mainly from the rear. I will repost with the results.

 

Before you go too far, carefully check the tires for a nail or
possibly a piece of tread that has come loose.
