I own a 1998 GMC Sonoma pickup, ZQ8 suspension, 105,000 miles. A few months
ago the suspension seemed to have gone out and began to bottom out.
The garage I deal with installed new shocks up front and that helped some. Then they
replaced the front springs and that helped a little more. The problem stills continues,
depending on the speed and the condition of the road. I went to a dealer and they could
not give me any definite answers. Their comment was to replace all the springs and see
if that worked, if not they would try something else. Not much of an answer.
I contacted GM and they said take it to a dealer.
Do you have any idea what I am dealing with?
Dear Sonoma owner,
I completely understand the problem that you are having. The only thing that I can think of is
if they didn’t put the correct shocks or springs on the truck as the ZQ8 requires its own special
set of either.
This type of suspension is designed to be a sport suspension and is designed to work together so
if one of the parts is mismatched this could result in your problem.
Take it back to the shop that you went to and share this info with them to see if they will make certain that they have used the correct shocks and springs.
Thanks for writing in and I hope that this helps,
