Can bad rear shocks cause swaying?
Worn-out shocks are among the significant causes of excessive sway in a vehicle and a feeling of looseness from the rear end. If shocks are worn out, the result is excessive body roll and a lack of control around corners.
Why does rear differential noise sound like a broken gear?

Noise results from a slight malfunctioning in the differential gears.
