Understanding the Problem
What the shock absorbers do and why they fail: The shock absorbers (suspension dampers) connect the tub to the washer cabinet and dampen the tub's movement during fill, agitate and spin. On Kenmore/Whirlpool-built top-load machines the absorbers wear out, lose damping, or the end clips break — producing loud banging, excessive vibration, tank-to-case contact, or the washer walking across the floor. Diagnostic and replacement steps: 1) Confirm the problem and order parts: Verify your model (110.45986400) and order the correct shock/suspension part(s). Most machines use a set of 2 or 4 shocks; replace all worn ones for balanced damping. If you’re unsure, check parts diagrams at the manufacturer or PartsDirect/PartSelect using the full model number. 2) Tools and materials: Flat screwdriver / putty knife, 7/16" or 1/2" nut driver or socket, needle-nose pliers, replacement shocks, towels or cardboard, work gloves, safety glasses, shop light. Optionally a helper and a strap to secure the tub. 3) Safety first: Unplug the washer and turn off the water supply. Move the washer away from the wall to access the back if needed. 4) Accessing the shock absorbers: There are two common access methods depending on cabinet style: a) Tilt-back access (most common): Pull the washer forward and tilt it back 45° onto a block so the front feet are elevated. Rest it on a block so it cannot fall back. This exposes the lower cabinet and the bottom of the tub. b) Remove the cabinet/top: Release the top panel clips with a putty knife at the seam behind the lid, lift the top, then remove the front or lower access panel to reach the shocks. 5) Support the tub: Before removing shocks, support the tub so it doesn't drop when shocks are removed. Use a strap, a block under the tub, or have a helper hold the tub in place. 6) Remove the bad shocks: - Inspect the shock ends. Most end fittings are either push-in/ball-socket with a retaining clip or a pin/bolt with a cotter/retaining clip. - If there is a metal spring clip, use pliers or a flat screwdriver to remove it. If there is a retaining pin or bolt, remove it with the appropriate nut driver or socket. - Compress the shock slightly if necessary, then pull the shock away from the mounting studs (top or bottom). Note orientation (which end faces up) and how the clip seats — you’ll reinstall the new shock the same way. 7) Install the new shocks: - Position the new shock in the same orientation as the old one. Snap the ball/sleeve onto the ball stud or align the pin hole and reinstall the pin/bolt and clip. If the shock uses push-on clips, ensure they fully seat and lock into place. - If the shock must be compressed to install, compress it slowly and seat both ends; do not force. - Replace every shock that shows play/leakage or soft damping — replacing in pairs or all four is recommended. 8) Recheck and reassemble: Remove any tub supports, lower the washer back to its feet (if tilted back), reinstall panels or cabinet top, reconnect water and power. 9) Test run: Run a spin-only or small load cycle and watch for excessive vibration, banging, or unusual movement. If it still vibrates, check that shocks are installed correctly and that springs, counterweights or tub bearings are not the root cause. Safety note: Always unplug the washer before any repair. When tilting the washer, secure it so it cannot fall; a falling washer can cause serious injury. If you’re unsure about supporting the tub or handling heavy components, get a helper or a professional technician.
Common Symptoms

Common Causes
- Worn shock absorber dampers (loss of oil or internal wear)
- Broken or missing mounting clips/pins
- Multiple shocks failed or uneven damping across shocks
- Related issues (worn tub bearings, loose counterweights, damaged springs) that mimic shock failure

Helpful Repair Tip
To confirm a shock is bad, push down on the tub near each shock. A healthy shock resists motion and returns steadily; a worn shock will feel loose, flop, or allow the tub to slam back. You can also remove a suspect shock and compress it by hand — it should provide firm, damped resistance (not move freely or leak oil).
Frequently Asked Questions
Do I need to replace all shock absorbers or just the noisy one?
You can replace just the faulty shock, but matched damping is important. If one shock failed due to age, the others are likely close behind. For best results, replace in pairs or all four to restore balanced suspension and prevent repeat failures.
How long does it take and can I do this myself?
A competent DIYer with basic tools can replace shock absorbers in 45–90 minutes. Time depends on cabinet style and whether a helper is available. If you’re uncomfortable tilting the washer, supporting the tub, or identifying correct parts, consider hiring a technician.
