Rear end moving around? Updated with pics

spike_africa · 09-04-2007, 08:37 PM

OK so i have been working on this for like 3 weeks trying to figure it out. My rear end when i hit the nitrous feels like its moving like its cocking to the passenger side when the nitrous hits. Feels fine otherwise around corners hard braking you name it. Just in a straight line on the gas feels like its moving. So i pulled the control arms off there all fine. Ok i though its gotta be the rear shocks lettings the car get nasty axle wrap. I do have stock shocks with bullit springs so there really blow out and bad. I have new front KYB struts and waiting on AM.com to give me my rear shocks.

Anyone else have some ideas if these shocks don't fix this? If it doesn't i got a feeling the posi is fucked and not sending power evenly and thus making the rear move around.

All i can say is this shit sucks right now.

well since you said something about the POSI no distributing the power evenly, that sounds like a really good possibility.

yeah its on there right now. But i just noticed my uppers the other day were looking weird and not sitting straight up and down on there bushing. I think i might of torn the upper control arm bushings. I wont know till this Friday when i can take a look at it.

So i took it apart Friday and sure enough i ripped the lower control arm bushings on the drive side this is why its been moving around only under hard thorttle. I have new ones coming from summit racing should be here Tuesday. Until then im stuck sharing a car with the g/f and her 94 rodeo.

Here are the ripped polyurethane bushings. I tore right threw them which sucks i hope these next ones last:
