'90 Corsica - Clunk coming from right trunk area when I stop...

I have a '90 Corsica. Recently I have noticed a clunking sound coming from the passenger side, trunk area.

It only happens when I come to a stop, and the sound usually comes about a second later, almost like there was something heavy in the trunk that would roll to the side of the trunk and make a clunk when I come to a stop (or near stop)......So I emptied the trunk out, but it still happens.

It does happen every single time I stop, but it happens most times. It's like a loud clunk coming from the right rear of the car.

Anyone have any idea what this could be?

Thanks.

Make sure your wheels lug nuts are on tight; a friend had a similar noise when starting and stopping but perhaps yours only does it on stopping. What kind of rear brakes: disc or drum? Could be a brake system part that is loose moving about. I'd ask a mechanic to check it out if you're not up to it.
Good luck.

Did you also check under the trunk carpet for a loose spare tire or jack/lug wrench, etc?

Strut/strut mounting plate issue????.............Also check the rubber insulators on the leaf spring going from left to right side............last but not least, check the rear brakes for leaking wheel cylinders..........Fluid on the brake shoes gives many an unuausl noise

lol...... Not a chance. I'm thinking the doghouse isn't quite airtight enough.

Tow guy - Checked that.
Wrench and Tow guy - Actually, I did have some back brake work done a few months ago. (I have no clue if they're disc or drum.) So after reading your message, I took the car in to them today and the mechanic said it was possible for brakes to make that sound if the adjustment was a bit off when they originally did them a few months ago, so just to make sure, they readjusted the brakes......but the sound remains. I was soooo hoping that was the problem.

I told them that I was concerned about the noise, because I didn't want to be driving down the highway and have some huge thing fall off the bottom of the car. Just 'not knowing' what is making the sound certainly scares me. They said it looked fine though...

Am now wondering tho - if the clunk was being caused by struts (I have no idea what they are), would that be something they would see under the car when they were readjusting the rear brakes?

Tx. again.

struts: the a (very simply explained) a very large shock absorber that is made strong enough to be used as a active member of the suspension.

It does not appear you car uses struts but just old fashioned shocks.

I have had shocks and struts cause a clunk sometimes. As the rear of the car raises when stopping (normal action when stopping) a worn shock or strut can bind. When releasing the brake, it can allow the bind to release causing a clunk, although ususally not much of one.



I would still consider the brakes though.

It appears you have drum brakes in the rear. One thing I would look for are worn backing plates. GM had a big problem with backing plates. Don;t remember the years and models though. They would wear where the brake shoes ride and the shoe could actually get caught on that groove. That caused clunks and the brakes wound up and then were released.

I think wrench47 is thinking about a W body GM that used the transverse leaf spring. A Corsica/Beretta used typical coil springs and shocks with a trailing arm setup.

Hi. I was just looking through my old postings and noticed I didn't get back to you guys with what the problem ended up being.

I took the car back to the place that originally did the brakes, and they said they seemed fine to them, but would re-adjust them at no charge. So they re-adjusted them, and the car still clunked and they said it wasn't the brakes.

I then took to the car to a different mechanic that went around the block with me... I asked him what the clunk was, and I 'didn't' mention that I had had any brake work done anywhere, and he immediately said.....'ahhhh - the clunk is the brakes. Had I had any brake work done recently? and that they were really poorly adjusted.'

So yes.....in the end, the problem was the brakes.

So going through my posts, I realized I hadn't gotten back to anyone with the end result, and after the time it takes for strangers to offer their advice/suggestions, the least I can do is get back with the outcome! So.....Thanks again for all the replies.

Marie
