Understanding the Problem
If your Samsung WA45T3400AP/A4 is banging, vibrating heavily during spin, or moving across the floor, worn or broken shock absorbers (dampers) are a common cause. The dampers control the tub’s movement during wash and spin cycles; when they fail the tub can oscillate freely, causing loud thumps, long spin times, and uneven wear on other components. Failing dampers usually result from long-term wear, torn mounts, or damage from an unbalanced load. Replacing the worn dampers with the correct OEM or compatible replacement parts will restore stability and reduce noise. Inspecting the dampers early prevents damage to the tub, suspension mounts, and cabinet, and often restores normal operation quickly and affordably.
Common Symptoms
Loud banging or thumping in spin, washer walks/rocks on floor, excessive vibration during spin, clothes very wet after spin, visible tub sag or uneven movement, intermittent click/pop from suspension area.
Common Causes
- Worn or torn shock absorber/damper seals allowing oil leakage and loss of damping
- Broken or detached damper end mounts or clips (plastic tabs fail)
- One or more dampers failed while others still hold — causes uneven damping and severe vibration

Helpful Repair Tip
Run a spin-only cycle with the lid closed and watch (or feel) the tub movement by opening the control panel or supporting the tub — excessive vertical or side-to-side travel (>1–2 inches) indicates worn dampers. Also check the damper body and mounting ends for oil leakage, torn boots, or broken plastic clips and tabs.
Frequently Asked Questions
How do I confirm the dampers are the problem?
Unplug the washer and remove the lower access panel (or tilt the cabinet back per your service manual) to visually inspect the dampers. With help, run a spin-only cycle and watch the tub movement: if it bounces excessively (more than ~1–2 inches), the dampers are likely bad. Look for oil stains, torn rubber boots, or broken mounting tabs on the dampers. Also try a manual press test: press down on the tub — it should resist and return smoothly; if it slams back or oscillates, damping is reduced or gone.
Can I replace the dampers myself and how long will it take?
Yes — replacing dampers on this Samsung top-load model is a straightforward DIY for someone comfortable with basic hand tools. Typical steps: unplug washer, tilt back or remove cabinet/top to access damper lower mounts, unclip/remove old dampers, install new dampers and secure clips, reassemble and test. Expect 30–90 minutes for one damper or 1–2 hours to replace a full set. Always verify part compatibility with your model/serial before purchase and follow safety procedures (disconnect power and water).
