Rear end noise from 2004 G35 MT
This is the wifes car, it's a 2004 MT with Brembo and around 105Kmiles. It has a whine from the rear that starts in about 40MPH. I dont think it's brakes or trans/clutch related as its unchanged by stepping on brake or pushing in clutch.
The noise is a whine and goes with the speed of the car in motion. Has gotten progressively worse over the last few mos. Am going to swap rear wheels with my G to see if its tires.
If its not that, what's the next most likely cause? I havent seen any leaks but I will check oil level in the differential. I assume the rear axle has outer bearings that can be changed? Any other thoughts on what might be the cause?
