apparently I have a "loose" rear end
so my girl's grampa says i got a loose rear end. and that is why i'm hearing a knocking noise from underneath in the back. cant be my u joint, we just replaced it thinking that was the problem. so he fiddled around underneath my car and says i have a loose rear end. and that the knocking isnt gonna do anything and the only way to get rid of this is to replace my entire rear end. what do you guys think? i respect the guy and all and he's really bright with cars but i'm sure getting more info from you guys (fellow LS1 riders) would help even more. thanks guys
further detail on the knocking sound: happens during first acceleration from a stop. speed dependent. happens only for 1-3 seconds.
thanks

when i'm accelerating from a stop. anywhere from 0-35 mph. also when i'm just cruising slowly and i accelerate a little it'll knock. it doesnt happen every time but it happens. sometimes i'll also hear a little thick metal "POP" sound with it.

ha ha ha. that sounds about right. he's a great guy though. sometimes he's on the money and sometimes he's close. he's got this like 80's Nissan/datsun z that just sits in his garage that he's been working on for a long long long long time. his tools just sit on top of it now.

i'm starting to think i should bring my car to a shop for free diagnosing and maybe an estimate. can you guys recommend a place? or is there anyone here from iowa?

ya, i would take it in. we cant really be much help without seeing and driving the car. i would take it to a dealership, find out whats wrong, then either find a shop that will do the work or come on here and we can you guide you through it.

Tell you what - go to autozone, get yourself some ramps. get it on top of them and look under the car - check the tranny mount by trying to lift it or shake it and if it moves alot then its bad or loose. check exhaust piping and all bushings ect. if you still dont know get youself a haynes manual and flip though that to help you out.

As said above, get under the car and manually move all of the suspension components on the rear...torque arm (bushing at tranny), tranny mount (lay on your back and 'bench-press' the tranny, if it comes up off the crossmember you have a bad mount), lower control arms, panhard bar. Also check exhaust components from front to back and see if its close to any of the floor panels...look for rub marks on components.
Also, good luck finding a shop that does "free diagnosis" unless you know the tech or owner of the shop. I live in West Des Moines and I'm a tech at a chevy dealership...used to live in Waterloo...doesnt help you much though.
