Drummer Posted April 25, 2010 Report Share Posted April 25, 2010 My grand Prix has been doing this for a while now. If I'm turning it will clunk a little but will get louder when when I'm turning and stepping on the gas. I just finished replacing both inner and outer tie rods cause they were bad and I thought they were possibly causing the clunking but of course they didn't. I'm thinking my sub frame bushings are starting to go, cause that's the only thing I can think of besides a motor mount. What are your opinions, thoughts?

Addicted to eaton Posted April 25, 2010 Report Share Posted April 25, 2010 what car? my Lower control arm bushings (A-arm). Thats my guess. Quote Link to comment Share on other sites More sharing options...
AL Posted April 25, 2010 Report Share Posted April 25, 2010 exact same problem happened with my friends cutlass... we replaced the strut, ball joint, subframe bushing, and i dont remember what else but it stayed the same... i noticed that her motor mount was literally destroyed but i didnt think that was it and she was tight on $$ so we didnt replace it Quote Link to comment Share on other sites More sharing options...
Schurkey Posted April 25, 2010 Report Share Posted April 25, 2010 Classic symptoms of wiped-out outer CV joint. Quote Link to comment Share on other sites More sharing options...
AL Posted April 25, 2010 Report Share Posted April 25, 2010 I wouldnt say that as thats one of the things I replaced on my friends cutlass and it still made the same noise Quote Link to comment Share on other sites More sharing options...
tornado_735 Posted April 25, 2010 Report Share Posted April 25, 2010 Yeah, I thought CV joint too, but they make more of a clicking noise. I drove on a bad one for 30,000 miles in my old AWD Aerostar  I suspect a ball joint/control arm. Maybe even tie rods. Quote Link to comment Share on other sites More sharing options...
Octavarium454 Posted April 26, 2010 Report Share Posted April 26, 2010 Ball joints or CV axles. Might as well do all of them as I'm sure they are all getting to the point where they will need replacing anyways. Quote Link to comment Share on other sites More sharing options...
Drummer Posted April 26, 2010 Author Report Share Posted April 26, 2010 well i'll try ball joints first as cv axle clicking is a completely different sounding noise from what I'm experiencing as it is a lot louder and deeper, and only clunks once, and even does it sometimes in a straight line. The weird thing is is that my Z34 did the very exact same thing and both the motor and transmission are from it so I don't know what to think.

redmetrix Posted April 26, 2010 Report Share Posted April 26, 2010 My 93 GTP did this also from when I bought it with 127,000 miles until I sold it at 137,000. Really the only time it would happen was backing out of my driveway, turning the wheel to the left. Never did try and figure out what was actually causing it.

RareGMFan Posted April 29, 2010 Report Share Posted April 29, 2010 My TGP did the same thing for a while. We checked everything typical (ball joints, CV axles, tie rods, etc), but couldn't find a damn thing wrong with it. Then I took it over to a buddy's to take one last look at it. He was jacking up the car from the subframe when I noticed the motor start going up with the jack..........while the car sat on the ground! Needless to say, first thing I did was look at the subframe bolts, and they were wiggling around like a loose tooth. The bushings were completely shot. I changed anything and everything associated with holding the subframe in. Quote Link to comment Share on other sites More sharing options...
AL Posted May 3, 2010 Report Share Posted May 3, 2010 And did that fix it? Quote Link to comment Share on other sites More sharing options...
RareGMFan Posted May 3, 2010 Report Share Posted May 3, 2010 Oh yes. I was on pins and needles till I could get it done, because it looked BAD. Kept waiting for the cradle to drop. But yes, once I got that done, not another peep. Quote Link to comment Share on other sites More sharing options...
4door Intl Posted May 3, 2010 Report Share Posted May 3, 2010 I was going to suggest the same thing, rotten rear cradle mount(s). Pretty easy to check, just duck under and inspect the condition of the rubber mount and look for any space betwen the cradle surface and the body.

Drummer Posted May 4, 2010 Author Report Share Posted May 4, 2010 yeah now I'm thinking subframe bushings as i couldn't get the wheels to move in any direction and it seems to make the clunking at different spots in the front soo where can I get good subframe bushings?

SigEpCutlass Posted May 12, 2010 Report Share Posted May 12, 2010 Check for a bad lower motor mount, and bad bushings in the suspension. My cutlass' suspension makes random noises every now and then, but it hasn't bothered me enough to find exactly what bushings need to be replaced.

Drummer Posted May 13, 2010 Author Report Share Posted May 13, 2010 well the lower motor mount was replaced a year or 2 ago but i guess it's possible it's just really irritating to have a car that makes this much noise when turning and accelerating.
