Understanding the Problem
The stock absorber (commonly called the damper or shock absorber) in the Samsung WA45T3400AP/A4 stabilizes the inner tub and reduces vibration during spin. Over time the dampers wear out, leak, or lose damping ability which lets the tub bounce, bang against the cabinet, or produce loud knocking and excessive vibration during spin cycles. This is especially noticeable with unbalanced loads or high-speed spins. Replacing worn dampers restores stability and quieter operation. Before buying parts, confirm the symptoms and inspect the dampers for oil leakage, broken mounting tabs, or excessive play. Damper part numbers and the number required can vary by production revision, so verify the washer model and serial number against a parts diagram when ordering replacements.
Common Symptoms
Loud knocking, heavy vibration or rocking during spin, tub hitting the cabinet, clothes tangling at high speeds, and visible oil or torn boots on the damper assemblies.
Common Causes
- Wear and age of the damper’s internal components leading to loss of damping
- Physical damage to damper mount or rubber boot from impact or overloading
- Manufacturing variation or wrong/weak replacement parts previously installed

Helpful Repair Tip
Visually inspect the dampers at the bottom of the outer tub with the top or front panel removed; if the rubber boots are torn or you can move the inner shaft by hand with obvious play, the damper is bad.
Frequently Asked Questions
How many dampers does the WA45T3400AP/A4 use and do I need to replace all of them?
Samsung top-load washers commonly use two dampers (sometimes four depending on design). Replace all dampers that show wear; if one is worn the others are often close behind, so replacing the full set is recommended for balanced performance.
Can I replace the dampers myself and how hard is the repair?
Yes — replacing dampers is a moderate DIY job. It typically requires removing the washer top and/or front panel, supporting the inner tub, disconnecting the old dampers from the tub and frame, and installing new ones. Basic hand tools and careful reference to a parts diagram or service sheet are required. If you're not comfortable working with large appliances, consider a repair technician.
