LCA Bushings on LT1

Hey,

I just bought my LT1 about a week ago and I am hearing squeaking from the rearend on speed bumps and rough surfaces. I believe the LCA bushings are the cause of this but I dont know were these are, can someone tell me were they are located and what they do? Sorry for the noob question but im still becoming familar with my car.

Thanks,
Chris

look on the front side of the axle, just inside of the brakes. you'll see a U shaped stamped steel bar running towards the front.

it has a bolt in the bracket on the axle and one on the frame.

more than likely it's your shocks not the LCAs
