How to Replace the Shock Absorbers on a Frigidaire Front-Load Washing Machine

Frigidaire EFLS front-load washers use 4 shock absorbers as part of their Perfect Balance suspension system. These shocks connect between the outer tub and the machine's base frame, damping the tub's movement during the high-speed spin cycle (up to 1200 RPM on some models). When shocks wear out, the tub swings excessively — causing banging against the frame, machine walking across the floor, and potential damage to the door boot seal and internal components.

Shock absorbers are a common wear item with a typical lifespan of 8-12 years. They fail gradually — you will notice increasing vibration over weeks or months, not a sudden failure. The part number for Frigidaire front-load washer shocks is 5304485917 (set of 2), and this is shared with equivalent Electrolux models.

Before You Start

• Tools needed: Phillips #2 screwdriver (rear panel), flat-blade screwdriver or pliers (pin release)
• Parts needed: 2 sets of shock absorbers, part 5304485917 (each set = 2 shocks, need 4 total, ~$40-$80 total)
• Time required: 30-45 minutes
• Difficulty: Intermediate
• Safety warning: Unplug the washer. The tub is heavy and supported by springs — do not put hands between tub and frame during work.

Step-by-Step Instructions

Step 1: Access the Shock Absorbers

Remove the rear panel by removing all Phillips screws around the perimeter (12-16 screws). The shock absorbers are visible connecting from the lower sides of the outer tub down to mounting points on the base frame. Each shock is a cylindrical tube (about 10-12 inches long) with a pin mount at each end.

Step 2: Test the Existing Shocks

Before replacing, confirm the shocks are actually worn. Grip each shock individually and push/pull along its axis (compression and extension). A healthy shock provides firm, consistent resistance in both directions — similar to a car's shock absorber. A worn shock offers little resistance, moves freely, or feels mushy. An oil leak from the shock body is a definitive failure sign.

Step 3: Remove the Old Shocks

Each shock connects at both ends via pin-and-socket mounts. The pin has a locking tab that prevents it from popping out during operation. To remove:

1. Locate the locking tab on the pin (visible as a small plastic tab protruding from the socket)
2. Press the tab inward with a flat-blade screwdriver while simultaneously pushing the pin through the socket
3. Once the pin clears the socket, the shock end is free
4. Repeat for the other end of the shock
5. Remove the shock

Do this for all 4 shocks. Work on one side at a time — the tub will shift slightly as you remove support, but the upper springs hold it safely.

Step 4: Install New Shocks

Position each new shock with the pin ends aligned with the sockets on the tub (upper) and frame (lower). Push the pin into each socket until the locking tab clicks into place. Tug the shock to verify it is locked — it should not pull free.

Install all 4 shocks. Verify each pin is fully seated — a partially-seated pin will pop out under the force of the spinning tub, causing sudden vibration and potential damage.

Step 5: Verify the Suspension

With all 4 new shocks installed, push the tub firmly to one side and release. It should return to center smoothly with minimal bouncing (1-2 oscillations then stop). If it bounces more than twice, a shock may not be properly seated or may be defective.

Push the tub downward and release. Same behavior expected — quick return with minimal bounce. If the tub continues bouncing, check the upper suspension springs as well — springs and shocks work together.

Step 6: Test Under Load

Replace the rear panel. Run a spin cycle with a medium load (6-8 pounds). The machine should spin with minimal vibration — no banging, no walking, no excessive noise. Frigidaire's Perfect Balance system allows some tub movement (you may hear slight rhythmic sounds), but it should not contact the frame at any speed.

Test with an unbalanced load (single heavy item like a towel) to stress the suspension. The machine should pause and redistribute or run at reduced speed — not bang violently.

Troubleshooting Common Issues

• Vibration persists with new shocks: Check machine leveling. Also check upper suspension springs for weakness. Finally, verify all shipping bolts were removed during original installation (4 red-capped bolts on rear).
• One shock pops loose during spin: The pin was not fully seated. Remove rear panel, verify the locking tab clicked into place, and ensure the socket is not cracked or worn.
• Machine still walks across floor: Walking is often a leveling issue rather than shocks. Adjust legs until spirit level reads true on both axes. Some Frigidaire models have self-adjusting rear legs — lift the front 4 inches and set down.
• Tub sits lower on one side: An upper spring may be broken or unhooked. Check the 2-4 springs above the tub with the top panel removed.

When to Call a Professional

• If the frame mounting sockets are cracked or broken — the shock cannot mount securely
• If the tub mounting points (shock brackets on tub) are corroded through
• If vibration persists after shocks, springs, and leveling are all verified — the counterweight bolts may be loose or concrete counterweight cracked

FAQ

Q: How many shocks does a Frigidaire front-load washer have? A: Four. Part 5304485917 is a set of 2 — you need 2 sets for all 4. Shared with Electrolux.

Q: How do I know if they are bad? A: Push/pull each shock — should offer firm resistance. Bad shocks move freely or leak oil. Also: excessive vibration, banging, walking.

Q: What is the part number? A: 5304485917 (set of 2). Same part fits Frigidaire and Electrolux washers of the same platform.

Q: Should I replace all 4 or just the bad ones? A: All 4. Mismatched shock ages create uneven damping and new vibration patterns.
