I dont know what I did or how to fix it....

The car is a '90 Convertible with the Z51 option

What I did was:

Last weekend I put the car on jack stands, removed the wheels to replace the calipers and rotors. While it was apart I cleaned the suspension - clean enough to eat off of... I used a scrub brush and several cleaners (WD-40, Simple Green, oven cleaner and Aluminum cleaner) after it was super clean, I lubed everything and sprayed the bushings with silicone - Re assembled everything and drove the car.

The problem:

Brakes work great, no new noises or squeaks! but when I pulled it back into the garage, I noticed the rear of the car seems to sit lower then the front and after a closer look, the driver side rear tire looks like it leans in at the top and is about 3/4 of an inch lower then the passenger side rear....

Before We did any work to the car it set level and the wheels were all straight..

I did drive the car for about 40 miles and switched the suspension to all the settings - Nothing seems to have changed it....

**Note** When I pulled the car off the jack stands, the driver side rear was the first off the stands - Could the "tweak" of the car being lowered to the ground have blown out the shock? It's not leaking...

I'm baffled... The car looks like crap with the front up in the air and the rear on the tires.... But the crossed drilled rotors, braided brake lines and painted calipers look great!!

Any help would be a great - as I now want to lower the car, but don't want to do anything until this problem is figured out...

I'm all ears!!

Did you remove or loosen the swaybar bushing when you had the suspension unloaded? When I replaced my swaybar bushings, I had to tighten everything up with the suspension at ride height, otherwise it looks like a monster truck.

Nope.... The only bolts I messed with were the calipers and the brake lines....

that is weird. can you provide us pics of the car as it sits right now?

I am wondering if the rear spring hasn't failed... and unloading it did it in. Weirder things have happened.

The problem has been solved by CF members....

Here is waht the deal is - The driver side of the rear spring is broken / cracked... I suppose when I let the car down from the jack stands, it put a large amount of stress on it and caused it to break/ crack/splinter..

Bogus - You have been very helpful in the past, can you suggest what I should replace when I swap the sping - bushings, bolts?

The car is a '90 Convertible (Corvette C-4 - I know you love it when they are referd to as this ) - just a joke, don't hammer me...

Thanks!
