I have a 94 Z28 and it squeals like crazy when i'm at a low RPM or when I go over bumps. It has new struts and I have replaced the sway bar mounting brackets because they were all bent up when I got the car. The only thing I can think of from here is ball joints - end links - or tie rod ends. I'm really hoping that it isn't a problem with the control arm. If it's any consellation I just replaced the water pump and the noise started shortly after that. I have zero power loss and it does not happen above 2000 RPM's. The front supsension, though, is very noisy altogether. Does anyone know what this might be or are experiencing the same problems?

Thanks - B

 

It is hard to see it as a suspension/chassis issue suck as sway bar/ball joints/end links etc. It wasn't the case in my last vehicle.

The fact that it doesn't happen above a certain rpm is weird. Does it make the sound while going over a bump when revving about 2k rpms? Try it out?

 

what about front brakes?

 

Yes it does over bumps. I even tried to move the cold air intake around because I tought maybe it was rubbing somewhere and nothing worked. That's why i was worried that it may be a suspension part because I have no power loss at all.
