This is my second attempt to describe this sound my car makes and I really cant figure out what it is.
Coming from rear axle area, starts at approx. 20mph and remains steady at any speed, no change from more speed, in gear, in neutral and just rolling, or decelerating to a stop, no change by using the brakes or park brake.
It sounds like a squeak toy. Or like a zipper being zipped really fast, or like two pieces of nylon fabric being rubbed together quickly. No metallic sound, no grinding really, no change with lateral g forces. My rear diff does make that shhhhhh sound but its not loud enough to hear inside the car.
I’m driving up to West Virginia tomorrow for a meeting and the noise worries me a bit. Using a temp gun I don’t find anything getting hot and I don’t smell anything that is baking.
The car is my ‘89 sedan 325i.
When I raise the car and start it, and run through the gears, it doesn’t make the noise so I think it only happens when the weight of the car is on the suspension.
