Default Rear Suspension Noise

Just picked up my V a few days ago and hands down love the car. One thing I notice is that when backing out of my driveway, once I come to the street (my driveway is on a small incline), the suspension makes a horrible clunking, squeak, boing sound in the rear. This also happens when hitting bumps in the road, etc.. The car has eibach springs, but the rear doesn't look lowered. I suspect the previous owner who had the springs put in didn't research about the nivomats. So either the springs are installed wrong, or I may have some bad shocks in the rear. The car has 60,000 miles, what do you think?

Check the swaybar endlinks they can come loose and cause the clunking your are describing

The links might be broken if they didn't change them out to Z06 links. Also, make sure the cradle mount bolts are tight. Check to make sure the shocks have the shims so they aren't trying to re-level themselves back to stock height.


Spraying lithium grease on things wouldn't hurt either.

Z06 links are only needed on the front.

I had the eibach springs with no spacer in the rear shock for a little while with no weird noise. Get the spacers though so it sits nice and level

I think it is missing spacers. the front is nice and low but the rear is still stock height...

Front is perfect no noise or anything

Get the spacers first then while your installing look for anything unusual. Mine made some weird noises before I put the spacers in, the car doesn't like riding on shocks only it seems
