Ford Escape rear-end clumping noise when backing up or pulling out on Ford Escape

Some Ford Escape owners report experiencing a clunking noise from the rear end when backing up or pulling out, which may be linked to issues with the Rear Drive Unit (RDU). Others have noted that the noise could stem from problems with rear control arms and bushings, as outlined in a Technical Service Bulletin (TSB). In certain cases, the clunking persists even after the right rear wheel bearing has been replaced, suggesting that the source of the problem may not be limited to that component. This issue appears to be prevalent across various model years and mileage ranges of the Ford Escape. Owners experiencing this noise are advised to have the Rear Drive Unit and rear control arms inspected to effectively address the issue.
