Ok, after replacing the rearend(rebuilt with about 10000), replacing a tranny(rebuilt with about 7000 miles on it), a driveshaft(3000 miles on it) I was driving home the other day and started hearing a clunking sound coming from what I thought was the rearend. It sounded similar to how it did when the rearend went(pinion shattered). I got home jacked the car up and ran the car in gear, i could hear the sound but could not tell where it was coming from. The only thing i know for sure is that the sound was NOT coming from the differential. I pulled the driveshaft out and spun the rearwheels by hand, nothing, i ran the car without the driveshaft and didnt hear anything from the tranny... Please any ideas about what could be making the noise

 

Loose rear LCA bolts will cause a clunking noise. Make sure that the bolts are tight.

 

where are the lca bolts?

 

U-joints, tranny mount, torque arm bushing, panhard rod bushings or bolts, LCA bushings ........

The lower control arms (LCA's) are bolted to the axle assembly and the chassis subframes, connecting the axle assembly to the chassis.

 

thanks for the help ill check everything this afternoon

 

i still havent figured out what is making the noise... i checked the lca bolts and a couple other botls and everything seems to be fine how do i know if any of the bushings or tranny mount are no good

 

just replace the tranny mount with a urethane one just in case its a cheap part and takes less than 25 min to install, prolly take longer to jack the car up than it will to install

 

i know how to replace those ive done them before on a friends car... would a bad tranny mount really cause a clunking or clanking sound though... id imagine it would mainly cause some vibrations?

 

it will cause clunking, when mine was bad it would clunk every time i shifted or blipped the throttle... even if thats not whats wrong its a cheap and easy to install part

 

illend up replacing it but im almost certain that thats not whats causing the noise... it sounds like a clanking sound that happens every time the wheels are spinning not just when shifting or gettin on the throttle... could any of those bushings be causing it?
