User Suggested Solutions

Inspect the drum for foreign objects, remove any debris, and check the condition of the bearings. If they are worn, replace them. Ensure proper lubrication before reassembly.
If the bearings are significantly worn, consider replacing the entire drum assembly, as it may be more cost-effective than just replacing the bearings.
If the washer is making excessive noise and you suspect bearing failure, run a diagnostic test (if available) to confirm the issue before proceeding with repairs.
