Rear axle noise on accel and decel
My 1996 Corvette has noise in the differential, it happens at freeway speeds, it sings on light throttle and coast, is this gear noise, the diff seems to have a little to much backlash. The car has 61,000 miles on it.

It is gear noise.The style of this car you will hear a little noise because of how the rear end sits close to the driver and it is open behind you kinda makes an echo effect. probably getting play in the carrier side bearings allowing the gear to "walk" a little causing the pitch to change. this is usually the first cause of failure.You can just replace the bearings and set back up but might still get some noise if it has created a new wear pattern on gear set. This noise will not affect performance or how long it lasts.
