Hi When I turn right or left my back wheels make a whinning noise. We had the wheel bearing changed twice and the knuckle and we had a wheel alignment and new tires. What do you think this noise could be?

Rear disc or drum?

Are you turning on blacktop?

Will it do it in reverse?

Found a TSB for updated rear diff. Fluid (PN 12378514). Drain and fill with new fluid, drive in a RH circle for 5 min. Then drive in a LH circle for 5 min. Then drain and fill again.
