Speed Queen Washer Shaking or Vibrating Excessively
Excessive shaking on a Speed Queen washer during spin is most commonly caused by an unbalanced load, improper leveling, or worn suspension components. Speed Queen's commercial-grade suspension is designed to handle heavy, unbalanced loads better than consumer machines — so when vibration is excessive, the cause is usually leveling or a single suspension component rather than a systemic mechanical failure. This guide covers the full diagnostic sequence for TC5, TR7, AWN, and AWNE series machines.

Common Symptoms
- Washer moves or 'walks' across the floor during the spin cycle
- Loud banging or thumping during spin
- Excessive vibration transmitted to the floor and walls
- Washer stops mid-spin with an unbalanced load error (uL code)
- Vibration is worse with small or single-item loads
Most Likely Causes
- 1
Leveling Legs Out of Adjustment (Most Common)
Speed Queen washers ship with all four leveling legs set to the same height, but floors are rarely perfectly level. Even a few millimeters of unevenness causes the machine to rock during spin, dramatically amplifying vibration. The front legs adjust manually; the rear legs are typically self-adjusting on modern models but can seize in older machines. All four legs must contact the floor firmly with no rocking.
- 2
Unbalanced Load
A single heavy item (towel, jeans, comforter) or a mix of very heavy and very light items creates an off-center load that causes the drum to orbit eccentrically during high-speed spin. Speed Queen's uL (unbalanced load) protection will interrupt spin and redistribute water, but if the imbalance is severe enough it can cause violent shaking before the sensor triggers. Redistributing laundry manually resolves most vibration issues.
- 3
Worn Suspension Rods (TC5/TR7 Top-Load)
Speed Queen TC5 and TR7 top-load washers use four suspension rods with plastic cup-and-spring assemblies to support the outer tub. Over time, the plastic cups crack or the springs lose tension, reducing the damping force during spin. A machine with worn suspension rods will shake more than normal on any load, not just unbalanced ones, and the shaking intensifies as the drum approaches full spin speed.
- 4
Failed Shock Absorbers (AWN/AWNE Front-Load)
Speed Queen AWN and AWNE front-load washers use hydraulic shock absorbers (similar to automotive shocks) to dampen drum oscillation during spin. A failed shock absorber — leaking hydraulic fluid or with a broken mount — reduces damping on one side, causing the drum to move asymmetrically and shake violently. Failed shocks are typically replaced in pairs to maintain even damping.
- 5
Worn Drum Bearing
The drum bearing supports the rear of the drum shaft. As the bearing wears, it allows the drum to wobble slightly off-axis, which creates vibration that increases with spin speed. Bearing failure is typically accompanied by a grinding, rumbling, or growling noise during spin. The drum may also have noticeable play when pushed from front to back.
- 6
Shipping Bolts Not Removed (New Installations)
New Speed Queen front-load washers ship with metal shipping bolts installed through the rear panel to lock the drum in place during transport. If these bolts are not removed before first use, the washer will shake severely and may be damaged during spin. The bolts are typically bright zinc or plastic-capped and are clearly visible on the rear panel.

Quick DIY Checks
Unplug the Speed Queen washer before removing any access panels, inspecting suspension rods, shock absorbers, or the drum bearing.
Do not operate a washer with suspected bearing failure — the drum can shift off-axis severely enough to damage the tub, wiring, and internal components. Confirm the diagnosis and repair before resuming normal use.
When tipping the washer to access self-adjusting rear legs, have a second person assist or brace the machine securely — Speed Queen washers are significantly heavier than consumer-grade machines.
- 1Check all 4 leveling legs: place a bubble level on top of the washer, front-to-back and side-to-side. Adjust the front leveling legs by turning them clockwise to raise or counterclockwise to lower. Tip the machine forward to allow the rear self-adjusting legs to reset (if equipped). After adjustment, rock the machine firmly — all four corners should be solid with no movement. Tighten the lock nut on each front leg after setting.
- 2Verify the washer is on a level surface: if the floor itself is unlevel (common in older homes, basements, or on tiles), leveling the machine's legs compensates only so much. For floors with significant slope, anti-vibration pads (rubber isolation pads) placed under all four legs both improve leveling tolerance and reduce vibration transmission to the floor.
- 3Check for an unbalanced load: open the machine mid-spin (if the lid/door allows) and redistribute the laundry evenly around the drum. For top-loaders, drape items loosely around the agitator. For front-loaders, add a small bath towel to balance a single heavy item. Avoid washing single large items alone — pair them with similar-weight items for balanced loading.

Repair vs Replace
Leveling and load balance adjustments cost nothing. Suspension rod and shock absorber replacements at $30–$80 are straightforward repairs well worth performing on a Speed Queen built for 10,000+ cycles. Even drum bearing replacement — the most involved repair — is economically sound given the machine's remaining service life.
Est. Repair Cost
$0 (leveling adjustment) — $20–$40 (anti-vibration pads) — $30–$60 (suspension rod kit) — $40–$80 (shock absorber pair) — $80–$150 (drum bearing)
Est. Replacement Cost
$900–$1,500 for a new Speed Queen top-load washer

Frequently Asked Questions
- Why does my Speed Queen shake more than other washers?
- Speed Queen top-load washers use a genuine agitator and run spin cycles at higher RPM than many consumer-grade machines — both of which create more inherent vibration than impeller-type or slower-spin washers. This is normal and by design: the commercial-grade suspension is engineered to handle it. If your Speed Queen shakes more than usual or more than when it was new, the cause is typically worn suspension rods (TC5/TR7) or shock absorbers (AWN/AWNE) rather than the machine design itself.
- TC5 vs AWN — different vibration causes?
- Yes — the TC5 and TR7 top-load models use suspension rods (spring-and-cup assemblies) while the AWN and AWNE front-load models use hydraulic shock absorbers. The diagnosis for each is different. On TC5/TR7, check the plastic cups on the suspension rods; on AWN/AWNE, look for hydraulic fluid leaks on the shock bodies. Leveling and load balance are relevant to both model families.
- Can overloading a Speed Queen washer cause permanent damage?
- Chronic overloading accelerates wear on suspension rods, shock absorbers, and drum bearings by increasing the forces these components must absorb every spin cycle. Speed Queen recommends loading the washer to no more than the rated capacity — typically 3.2 cu ft for TC5/TR7 and up to 4.4 cu ft for larger AWN models. A single overloaded cycle is unlikely to cause immediate damage, but consistent overloading shortens component life significantly.
- How often should I check the leveling legs?
- Check leveling legs annually, or whenever the washer is moved. The machine can migrate slightly on smooth floor surfaces over time, especially in homes where the washer is on a tile or vinyl floor. A quick check with a bubble level and firm push on each corner takes under 2 minutes and eliminates the most common cause of washer vibration.
