Understanding the Problem
What this is and why it matters: Worn or broken shock absorbers (dampers) on an LG WM2010CW allow the wash tub to move uncontrolled during fill and spin. That produces heavy vibration, banging, loud thumps at spin speed, and sometimes a tub that slams back into the cabinet. Replacing the shocks restores stable tub movement and quiet operation. Step-by-step diagnosis and repair (practical how-to): 1) Confirm the symptom: Run a spin-only or a quick wash without clothes. Watch the tub while it spins — if the tub violently rocks, hits the sides, or continues to bounce after you stop manually pushing it, shocks are likely bad. Listen for loud banging at spin speed. 2) Unplug and prepare: Disconnect power to the washer. Turn off the water if you will remove any hoses. Pull the washer away from the wall for access. Wear safety glasses and gloves. 3) Access the shocks: For the WM2010CW remove the lower front access panel (or the back panel on some installations) to reach the shock top/bottom mounts. You may need a #2 Phillips and a 5/16" or 8mm socket. 4) Support the tub: Before removing a shock, support the tub so it won’t fall — use a block of wood or have a second person hold the tub. The shocks connect between the tub assembly and the washer frame; once removed the tub can drop or shift. 5) Remove the old shock: Most LG shocks use spring clips or a retaining pin/metal clip at each end. Pry out the clip (needle-nose pliers) or remove a retaining pin, then pull the shock off the studs. If it’s corroded, spray penetrating oil and let it sit a few minutes. 6) Inspect and compare: Check the removed shock for oil leakage, bent shaft, or loose mounts. Compare the new shock length and mounting style to the old one to confirm match. 7) Install the new shock: Slide the new shock onto the upper stud, push it fully over the mounting pin, and secure the retaining clip/pin. Do the same on the bottom. Ensure the shock is oriented the same way as the old one (most are not directional). Replace any mounting bushings that came with the new shock. 8) Repeat as needed: Replace all shocks that show signs of failure. It’s common to replace shocks in pairs or all at once for even performance. 9) Reassemble and test: Reinstall the access panel, restore power, and run a spin cycle to confirm the tub runs smoothly and no loud banging occurs. Safety note: Always unplug the washer before any repairs and support the tub before removing shocks. If you’re unsure about safely supporting the tub or working under the washer, consider calling a pro.
Common Symptoms
Excessive vibration or rocking during spin, loud banging or thumping at spin speed, tub slams back into the cabinet, uneven loads ride badly, visible oil or loose/bent shock bodies.
Common Causes
- Worn internal damping (oil leakage or worn seals) in the shock absorber
- Broken or bent shock shaft or mounting hardware
- Worn mounting bushings or clips allowing excessive play

Helpful Repair Tip
Push down firmly on the tub and release — if it bounces back quickly or slams, the shocks are bad. Also look for oil on the shock body; leaking oil = replace.
Frequently Asked Questions
Do I need to replace all the shocks at once or can I replace just one?
You can replace a single failed shock and the washer will run, but shocks wear together. Replacing them in pairs or all at once is recommended for balanced damping and to avoid having to open the washer again soon.
How long does it take to replace the shocks on an LG WM2010CW?
For someone with basic tools and mechanical comfort, replacing a set of shocks typically takes 30–60 minutes. If you need to locate stubborn clips or support the tub carefully it can take longer. Always allow extra time if you haven’t done this repair before.
