Car has about 80,000 miles and have noticed a "grinding" kind of noise from the rear of the car. This happens at low speeds when I am turning. It has been suggested that it is a problem with the differential, possibly ring and pinion gears, or bearings. I've been told it could cost up to $1,500 to fix the problem. Does any of this sound correct?
Doubt it very much
the only gears in action are the axle spider ( spur gears ) and they turn very slowly on turns
pinion and crown wheel, noise are growls and whines depending if accelerating or costing and makes no difference if turning or straight ahead That should save you $ $1500.00 for a diff center that costs only $450.00
indicates wheel bearings or brake pads ( linings ) worn out and the callipers rubbing on the rotor ( drum)
I would be checking at the wheels and wheel bearings for the problem

SOURCE: rear wheel bearings
First check the brakes on that side. You may be hearing the warning rivets on the brake lining. If it's good, You need to remove the axle and go to the machine shop and have a new bearing pressed on. The machine shop should only charge you about $20.00 to do this.

If you have the caliper and retaining rings off the park brake must be holding it. This vehicle has small parking brake shoes that apply to the inside of rotor hat. Try backing off the adjustment and tap the sides of the hat to free them up.
