Help my find this mysterious clunk.

Hey guys, I pulled the axle with the tranny do to a gear swap and tranny rebuild. Everything was fine for about 400 miles and then i developed a clunk in the back from the axle area. Its pretty much just between the 1-2 which is pretty hard from the shift kit. It seems like a heavy metal object hitting the chassis or something. Its not the tranny mount bc its still good and i know the differance between this noise and the tranny mount clunk. I raised the car on jack stand and took all the weight off the axle. I got underneath and couldnt seem to find and loose bolt, i also tried shaking the axle back and forth but it wouldnt budge.. The noise also sounds like the hatch is loose and is clunking forward but i got out and tried to pull on the hatch but i couldnt get it to budge.The bushings around my shocks are pretty cracked up and in bad shape. If my shocks were bad would it cause the axle to clunk like this? Thats for all input, Dustin.

Re: Help my find this mysterious clunk.

if you're sure it isn't the tranny mount....

my money is one either the torque arm mount or the LCA bolts not being tight enough.

i know when i installed my LCAs i thought i had them tightened down...when i hit bumps though it would make a nasty clunk.

got back under it and put some SERIOUS torque on the bolts and it solved the problem.
