A washing machine suspension kit is a critical component that keeps the drum balanced during spin cycles. If you own a Simpson SWT704 washer, the suspension kit absorbs vibration and prevents excessive movement. Over time, the springs, rods, or dampeners can wear out, leading to loud noises, shaking, or even leaks. Replacing the suspension kit restores smooth operation and extends the life of your machine.
What Is the Simpson SWT704 Suspension Kit?
The Simpson SWT704 suspension kit is a set of parts designed specifically for the SWT704 model (and compatible models). It typically includes the suspension springs, rods, and sometimes the dampener pads. These components work together to support the wash tub and absorb shock during spinning. Without a properly functioning suspension system, the drum can knock against the cabinet or walk across the floor.
Role in Washing Machine
The suspension assembly holds the inner drum in place while allowing it to move slightly during wash and spin cycles. This controlled movement is essential for effective cleaning and water extraction. When the suspension fails, you may notice the drum is sagging, or the machine becomes unbalanced frequently.
Compatibility and Model Identification
Before purchasing, confirm that the kit is designed for the Simpson SWT704. The SWT704 is a top-loader washing machine. However, Simpson also produces other models with similar suspension parts. Check the model number printed on the back panel or inside the lid. Cross-reference with the part numbers listed on the kit. Genuine Simpson suspension kits usually have a part number like 34003240 or similar.
How to Confirm Your Model
- Check the serial plate sticker on the back of the washer.
- Look for a tag on the inside of the lid or door.
- Write down the full model and serial numbers.
- Compare with the kit’s compatibility list—most reputable suppliers list which models work.
If uncertain, contact Simpson customer service or a certified appliance parts dealer. Using the wrong kit can cause improper fit or performance issues.
Signs You Need a New Suspension Kit
- Loud banging or thumping during the spin cycle: This often indicates worn suspension rods or springs.
- Excessive vibration: The machine shakes or moves across the floor.
- Drum sagging: The inner tub hangs low or touches the outer cabinet.
- Unbalanced loads: The washer frequently stops mid-cycle to redistribute clothes.
- Leaks: A damaged suspension can cause the drum to shift and stress seals.
If you notice any of these symptoms, inspect the suspension components. Look for broken springs, bent rods, or missing dampeners. Replacing the whole kit at once is usually better than replacing individual parts.
Installation Overview
Replacing the suspension kit on a Simpson SWT704 is a moderate DIY job if you have basic mechanical skills. However, always prioritize safety—unplug the washer and disconnect water hoses before starting.
Step-by-Step Basics
- Access the suspension area: Remove the back panel or front cover, depending on your model. On top-loaders, you often access the suspension from the bottom after tilting the machine.
- Support the drum: Use a block or a helper to hold the drum in place while removing old rods.
- Remove old suspension springs and rods: Note how each part connects. Take photos for reference.
- Install new parts: Attach springs to the frame and drum brackets. Ensure rods are properly seated in their sockets.
- Reassemble and test: Reattach panels, reconnect water and power, and run a short cycle without clothes to check for smooth operation.
If you’re not comfortable with repairs, hire a qualified appliance technician. Incorrect installation can damage the machine or cause injury.
Where to Find Genuine Parts
For reliable performance, use genuine Simpson parts or OEM equivalents. Counterfeit or aftermarket kits may not fit precisely or last as long. Purchase from:
- Authorized Simpson service centers
- Local appliance parts retailers that stock OEM components
- Online stores specializing in appliance parts (verify they are authorized distributors)
When ordering, provide your model number and the specific part number from your owner’s manual or existing parts. Avoid vague listings that only say “fits Simpson washers”—confirm compatibility directly.
Final Recommendations
If your Simpson SWT704 is experiencing shaking or noise, replacing the suspension kit is a cost-effective fix. Stick with genuine parts to ensure proper fit and longevity. Before buying, double-check your model and the kit’s part number. If you’re handy, follow a detailed guide; otherwise, professional installation is worth the peace of mind. A stable drum means quieter operation and fewer future repairs.
