Whining coming from rearend in a 1992 corvette with a 375 gear. how to fix or stop noise.?
If your gear set is worn, replace the differential with one from a scrapyard.
It is very expensive and an exacting science to set new gears up. if noise is from either carrier side bearing it is possible to replace them but generally if there is debris inside the unit the pinion bearings will be affected as well, requiring re-setting of gears. Depending upon what you ask from your vehicle, this is a good opportunity to change ratios. If you don't need all the bottom end performance, you could opt for a 3.23 ratio. If you are looking for more "off the line" power then go to 4.11's. Don't forget though that anything but the exact match to yours will require a speedometer drive gear change .You cannot stop the noise without making a repair.
