problem...popping noise

[cheeseburger35]

i have a 92 chevy pickup and i have a popping noise coming from the rear... but it only makes the noise when i swing the truck to the left...ie turns and everything....its not my u-joint... i don't know what else it could be....any help thanks

Is it a 4x4? If so, it could be the torsion bar(s).

2wd but i has front and rear sway arms...i'm wondering if these are causing it??

Could be the rear sway bar link pins. Check them for looseness. If i remember they are really cheap to replace. Also check the sway bar bushings.

what are the sway bar link pins??

[joe92k1500]

The pins connect the ends of the sway bar to the suspension. I checked my Haynes manual last night, and it does not list a sway bar for the rear. Could it have been added aftermarket? If not then I guess the book is not perfect.

yes its aftermarket... i don't know what brand or anything

Check your rear diff fluid level. Does the rear diff have posi/limited slip if so the additive in the fluid might be worn out . Very common GM problem

[cheeseburger35]

it might be a limited slip.........the fluid was changed 4 months ago....?? would it already be bad?

[Fireplug]

Did you change it or some one else do it and was the limited slip additive put in. Its not part of the gear oil its a add in limited slip oil

[cheeseburger35]

no it had a seal go bad and i didn't have time to fix it so i put it in a shop i'm not even sure it has a limited slip it just feels like it does
