91 ZR-1 - Weird sound from suspension - ZR-1 Net Registry Forums

MuRCieLaGo · 04-28-2017

Hi guys,

I'm hearing a weird sound from my rear left, whenever the car is under way and being stopped. Going forward is worst than going reverse, sorry I couldn't get a better video than that. The faster I go before stopping, the worst it'll be. Any idea? Sounds like a blow off valve from a turbo car.

Jack up the rear and see if it changes.

Cold bushings?

I can't jack up the car and go forward or reverse!

Oh that might be! Was cool outside that day, only drove the car for a couple of hundred feets or so to store it inside. Will check it out next month (I'm gone at sea).

Did you check you fan to see if there is something loose? I had a sound like that once on a different car and then I lost a blade on the fan, it went through the radiator BTW!

Hmmm, I really don't get what you mean. Noise clearly comes from the rear left.
