Understanding the Problem
Brief explanation: A washer suspension spring (often called a drum or tub suspension spring) supports the inner tub and keeps it centered while the washer fills and spins. "Mod 110" sounds like a model/part identifier for a suspension spring or a kit — functionally it’s the same as other washer suspension springs: it holds the tub up and absorbs motion. When a suspension spring weakens, breaks, or detaches, the tub can sag, bang against the cabinet, vibrate excessively, or make loud thumping noises during agitation or spin. Step-by-step diagnostic and repair steps: 1) Confirm the symptom: Run an empty diagnostic or spin cycle and observe. Look for excessive vibration, tub contact with cabinet, loud banging, or the tub sitting off-center. Note whether the issue happens every cycle or only on high-speed spin. 2) Access the suspension springs: - Unplug the washer and shut off the water supply. - For top-load washers: tilt back the cabinet or remove the cabinet/top to access the springs connecting the tub to the frame. For front-load washers with suspension springs at the rear, tip the washer forward after securing the front or remove the rear access panel to view suspension points. Consult your model’s service manual for panel removal steps. 3) Inspect the springs and mounting hardware: - Look for broken coils, severe corrosion, stretched/elongated springs, or detachment from the receiver hooks/brackets. - Check the top and bottom mounts for wear, cracked plastic retainers, or bent brackets. - With the tub unloaded, use gloved hands to press/pull on the tub — excessive sag or wobble indicates weak or broken springs. 4) Isolate the cause: Weak springs will allow too much vertical movement; broken springs or detached ends will let the tub lean or touch the cabinet. If shock absorbers (dampers) are used instead of springs, inspect them too—worn dampers produce similar symptoms. 5) Replace the springs (how to fix): - Obtain the correct replacement springs for your washer model (check the model tag inside the door or on the back). If your part is billed as "Mod 110", confirm that matches the replacement kit specs. - Support the tub before removing springs. Use a helper or a wood block under the tub to hold its weight so the tub doesn’t fall when you detach springs. - Detach the old spring: unhook one end at a time (use pliers if needed) and remove any retaining clips. Keep track of orientation and any washers/spacers. - Install the new spring: hook one end into the frame or retainer, align the tub, and hook the other end. Make sure spring ends seat correctly in their receivers and any plastic clips are replaced. - If multiple springs are worn, replace the full set to maintain balance. 6) Reassemble and test: - Refit any panels or the cabinet, restore power/water, run a test wash/spin with no laundry. Observe for balance and noise. If vibration continues, double-check spring seating and confirm shock absorbers or mounting brackets are not damaged. 7) When to call a pro: If the tub is damaged, mounts or the outer cabinet are bent, or suspension hardware is welded/pressed into place, call a technician. Also call a pro if you’re not comfortable supporting the tub safely. Safety note: Always unplug the washer and shut off water before working on it. Use proper supports for the tub — a falling tub can injure you or damage the machine. Wear gloves and eye protection when handling rusted or stretched springs.

Helpful Repair Tip
To confirm a bad suspension spring quickly, support the tub with a block and remove one spring at a time—if the tub droops or the machine's behavior changes noticeably with a spring removed, that spring was contributing to the problem. Replace springs in matched sets when possible.
Frequently Asked Questions
How do I know if I need to replace a single spring or the whole set?
If one spring is visibly broken or the tub noticeably sags on one side, that single spring is faulty. However, springs work as a matched set; if one failed from age, the others are likely weakened too. For best results and long-term balance, replace all springs at once if any show wear or if the washer is old.
Can worn shock absorbers cause the same symptoms as bad suspension springs?
Yes. Many front-load washers use shocks/dampers instead of (or in addition to) springs. Worn shocks allow the tub to bounce and will cause similar vibration and noise. Inspect both springs and shocks; replace whichever component shows wear.
