supersonic noise coming from the back of my car......??
 

I have a 1990 n/a coupe and ever since I put it on the road there is a super sonic noise thats coming from the back........It sounds like the wheel bearings or the differential................I can smell like theres something burning in the back when i smell in the rims.......................what could it be........??

I having a similar problem! The noise is like having a couple of crickets in the trunk. I guess, one of the bushes needs a bit of lubricant, but cannot find which one. I even cannot locate which side the noise coming from.

The same thing happened to our Z last week. The smell of fish, the sound of rocks banging around, the "yang"ing sound. I hate it. We thought it was the diff. we dropped in a new LSD tonight, and were testing it tommarow, I'll shoot you guys back tommarow and tell you how it goes. later.

Problem solved, except the "yang"ing sound it still there, it almost sounds like rally cars sound. But I guess its the diff. So if you have got the money, go for some LSD, it will trip you out. haha peace
