Rear Suspension Help Cleveland Ohio

Hello There Everyone

I need a little help/advice. I have a 13 and am experiencing, what seems to me, odd rear suspension behavior. The rear seems very very stiff. Also, when going over multiple imperfections in the road in a row, the rear feels like it is skipping/floating to the right. I must be sure to have 2 hands on the wheel.
I have it set on Tour mode.

I have been going to the local car shows looking for another ZL1 in hopes of chatting with the owner. Unfortunately, I have been unable to find one.

Any insight/suggestions are appreciated.

Thanks,
Ed

Your rear shocks are probably leaking and need to be replaced.

If your rear shocks are leaking they aren’t going to be stiff, they are going to be soft and bouncy.

Any time the car bounce-slides when turning is a sure sign of bad shocks/struts.

However, the rear multi-link suspension requires alignment. If it's off, the car can
slide on bumps, or if bushings are bad.

The only case where the struct would get harder is if it were bent. And its location on the Z makes that almost impossible with out bending the trailing arm.


I am not saying he doesn't have a strut issue, but the description he gave would not match that of a failed strut, but more of a collapsed bushing in either the lower arm or something else.

Thanks for the replies. Upon inspection, there is a fine oil mist on the right rear suspension. Also, when I bought the car I found out it was wrecked in the right rear and the suspension is not original on that side.

What kind of alignment do I need? Is there something special for the rear or is it just a normal front/rear alignment?

Thanks,
Ed
