Rear Noise - Page 2 - ZR-1 Net Registry Forums

I agree with Jim! It happens so much with my D3's that it's just back ground noise and I don't think about it much any more.

I notice that my GS-D3's will make different pitch noises depending upon the road surface material. Cement is the surface that really makes them sing, kind of like a stuka in a dive! Even different types of asphalt will yield different pitched noises.

Rick, just for chits & giggles, I'd give a check to the fluid level in the gear. JMHO.

Jim, I'd check the gear fluid level anyway. My car sat a lot before I got it and well seepage isn't the word for it....the seals thought they had no work to do. They seeped badly thru the first two fluid changes and then stopped. Low fluid level & or worn out fluid could cause a rear to make a low pitched growling noise....kind of the same noise a manual trans makes when it's low on fluid.

Yeah bro but even when they were new this sound was there. And transitioning to different road surfaces makes no difference. I can always count on it letting me know its still there. I am suspicious of rear gears or at least something to do with that area. You would think a giant bumble bee is on your tail.
