The tub seal is a small but critical component that protects your washing machine’s drum bearings from water contamination. When it fails, water silently destroys the bearings, leading to one of the most costly washer repairs — and eventually machine replacement if ignored.
Our Winnipeg repair team replaces tub seals and bearings together, as these jobs are always done in tandem.
Where Is the Tub Seal?
Front-Load Washers
Located at the rear of the outer tub, where the drum shaft exits:
- Shaft goes through the tub wall
- Seal wraps around the shaft
- Prevents tub water from leaking along the shaft
- Protects the rear bearing
Top-Load Washers
Located at the bottom of the tub, where the agitator shaft passes through:
- Also called the tub seal or basket seal
- Protects the gearcase and transmission area
- Some models use a bearing/seal combined assembly
Why Tub Seals Fail
Normal Wear
After thousands of spin cycles, the seal material wears:
- Rubber hardens over time
- Lip seal loses its grip
- Usually after 8-15 years of use
Water Infiltration from Previous Seal Failure
If the seal starts to leak slightly:
- Water reaches the bearing
- Bearing corrosion begins
- Corroded bearing actually accelerates seal wear
- A destructive cycle begins
Overloading
Heavy loads:
- Apply more lateral force on the drum shaft
- Cause the seal to flex more than designed
- Accelerate wear
Manufacturing Variation
Some machines develop premature seal failure due to design factors or manufacturing variation.
Signs the Tub Seal Has Failed
Brown or Rust-Colored Water
Rust from corroding bearings washes into the drum during fill.
Rust Stains on Clothes
Metal particles and rust settle on clothing during wash cycles.
Wet Spot Under Machine
Water escaping past the seal drips from the machine base.
Bearing Noise
Almost always accompanies seal failure:
- Roaring during spin cycle
- Gets louder as bearings corrode further
Water Under the Machine
Visible pooling underneath, often confused with a hose leak.
The Tub Seal and Bearing Connection
These two components are always replaced together because:
- Tub seal failure → Water reaches bearings
- Bearings corrode from water exposure
- Corroded bearings → Bearing noise and wobble
- Damaged bearings → Accelerate seal wear further
- Replace both or the new seal will fail quickly
It’s not economical or effective to replace one without the other.
Tub Seal/Bearing Replacement Process
This is a significant repair requiring full drum disassembly:
Front-Load Washers:
- Remove front panel and door seal
- Disconnect drum from front support
- Remove rear panel
- Extract drum from rear tub
- Press out old bearings using bearing press
- Replace rear seal
- Press in new bearings
- Reassemble in reverse
Top-Load Washers:
- Remove agitator and basket
- Access tub from inside
- Remove and replace tub seal assembly
- Often combined with bearing replacement from below
Cost of Tub Seal and Bearing Replacement
Combined bearing and seal replacement:
- Front-load washers: $200-$400 (labour-intensive)
- Top-load washers: $150-$300 (depending on access)
Parts include:
- Bearing set (usually inner and outer bearings)
- New tub seal
- Rear drum seal
Labour includes:
- Complete drum disassembly
- Bearing press work
- Reassembly and testing
Is Tub Seal/Bearing Replacement Worth It?
| Machine Age | Recommendation |
|---|---|
| Under 5 years | Always repair — premature failure |
| 5-8 years | Almost always worth repairing |
| 8-12 years | Assess overall machine condition |
| Over 12 years | Compare repair vs. replacement carefully |
Key question: Is the rest of the machine in good condition? If other components are also near end of life, replacement may make more sense for older machines.
