How to Replace Washing Machine Drum Bearings: When It Is Worth the Repair
If your washer is thumping, grinding, or leaking from the rear drum seal, the drum bearings are likely shot. The short answer: replacing them is worth it only if the machine is less than 8–10 years old and the repair cost stays below about half the price of a new equivalent model. For older budget machines, the labor and parts (often $250–$400) typically exceed the appliance’s remaining value. This guide walks you through the actual replacement procedure, shows where DIYers commonly mess up, and gives you a concrete decision checklist so you don’t throw good money after bad.
Before You Start: Shutdown, Tool List, and Part‑Number Verification
Working on the bearing assembly means disassembling most of the washer. Plan on a full afternoon.
Shutdown and safety
- Unplug the machine or flip the breaker.
- Shut off both hot and cold water supply valves.
- Disconnect the drain hose and water inlet hoses.
- Have a drop cloth and several large towels ready—leftover water will drip.
Tools you’ll need
- Set of Torx, hex, and Phillips screwdrivers (common on Whirlpool, Samsung, LG).
- 10‑mm and 13‑mm socket wrench set.
- Rubber mallet for tapping out old bearing races.
- Bearing puller or drift punch for the rear bearing.
- Multipurpose grease that is water‑resistant and high‑temp rated.
- New drum bearing kit – includes front and rear bearings, seal, and sometimes the spider hub. Do not reuse the old seal.
- Propane torch or heat gun (only if the bearing race is seized on the shaft).
Part‑number check
Write down the machine’s model and serial number (usually inside the door frame or on the back panel). Cross‑reference with the manufacturer’s parts diagram. Many bearing kits are model‑specific—buying a generic universal set will almost certainly result in the wrong inner diameter. If you need a broader overview of the process before diving in, check this detailed resource on how to replace a bearing on a washing machine.
Removing the Drum: What You’ll Find Inside
The process varies slightly between top‑load and front‑load washers, but the core six steps are the same for front‑loaders (the most common type that uses drum bearings).
Step 1: Remove the Rear Panel, Belt, and Motor
Unscrew the back cover. For LG and Samsung machines, you will also need to remove the top cover and control panel to access the rear. Loosen the drive belt by pivoting the motor (usually a 13‑mm bolt) and slip the belt off the drum pulley. Unplug the motor harness, unscrew the motor mount, and pull the motor out.
Step 2: Extract the Drum and Spider Assembly
Remove the plastic door boot clamp and push the rubber boot inside the drum. Pull the front panel off (on many machines it is held by two screws behind the door boot and two clips at the top). The drum with the rear spider is now accessible. Tilt it forward and lift it out. Place it on a clean work surface.
Step 3: Inspect the Spider Before Proceeding
Look at the metal spider hub bolted to the back of the drum. If you see cracks, heavy rust pitting, or a bent arm, stop. A damaged spider cannot be straightened, and installing new bearings into a bent hub will destroy them within a few cycles. This is your first decision branch: if the spider is bad, the repair cost jumps to $150–$250 for a replacement spider plus the bearing kit, and the labor doubles. For a machine over seven years old, that combination often pushes you into replace territory. If the spider looks clean and undamaged, proceed with the bearing extraction.
Step 4: Disassemble the Spider from the Drum
The drum spider is the three‑ or four‑arm metal piece bolted to the back of the drum. Remove the bolts holding the spider to the drum (often Torx T‑25 or T‑30). On machines with a solid rear drum, you will need to press the bearing out of the drum housing. This is the hardest part – a bearing puller saves hours. If pulling, heat the outer race with a torch for 30 seconds, then use the puller.
Step 5: Replace Both Bearings and the Rear Seal
Clean the bearing seat inside the drum housing with a wire brush. Press the new rear bearing into the housing (seal side facing outward). Tap evenly with a socket that matches the outer race diameter. Grease the inside of the new seal, then press it into place (lip facing inward toward the drum). Install the new front bearing if your kit includes one (many front‑loaders only have a rear bearing). Follow the same press‑fit method.
Step 6: Reassemble the Drum and Spider
Reattach the spider to the drum, torquing the bolts to spec (usually 10–12 ft‑lb; check your manual). Slide the drum and spider assembly back into the machine. Make sure the drum shaft seats squarely into the bearing – do not force it.
Step 7: Reinstall Motor, Belt, and Panels
Align the motor, tighten the mount, and reconnect the harness. Loop the belt back over the drum pulley and adjust tension per manufacturer spec. Reattach the rear panel, top cover, front panel, door boot, and hose clamps.

Where People Get Stuck: Reassembly and Routing Mistakes
Three errors cause most repeat failures:
1. Not replacing the tub seal – Reusing the old rubber seal guarantees a leak inside a few loads. Always install a fresh seal from the bearing kit.
2. Mixing up belt routing – Snap a photo of the belt path before removal. On some LG models, the belt must go around a tensioner idler, not over it. Routing it wrong slips the belt off during the spin cycle.
3. Forgetting the counterweight bolts – Many front‑loaders have concrete or plastic counterweights bolted to the rear drum housing. If you leave one loose, the machine will walk across the floor on high spin. If your machine is drifting sideways during spin, review the common causes of a washing machine drum off balance before assuming the bearings are the only issue.
How to Confirm the Repair Worked
After reassembly, run a drum clean or rinse + spin cycle with no laundry. Listen carefully:
- No grinding or knocking during spin.
- No water dripping from the rear of the drum (if you see a puddle, the seal is misaligned).
- The drum spins freely by hand with only minimal resistance from the belt.
Concrete wobble check: With the door open, push the drum firmly from side to side at the three‑o‑clock and nine‑o‑clock positions. Movement should be less than 1/8 inch. Any more than that means the bearings are not seated fully or the spider is bent. If you see visible wobble, stop and disassemble—do not run a second cycle.
If it passes these checks, load a small test load (2–3 towels) and run a normal cycle. A smooth, quiet spin means the bearing replacement succeeded.
When to Pull the Plug: Stop/Escalate Threshold
You should stop DIY efforts and either call a pro or replace the machine if you encounter any of these:
- The drum spider is cracked, heavily rusted, or one arm is bent.
- The bearing race is seized so badly that heating the housing for 60 seconds with a torch still will not let it budge. Forcing it with a hammer risks cracking the drum housing, which is not replaceable separately.
- You remove the old bearings and find the drum housing bore is gouged or out‑of‑round. New bearings will not seal in a damaged bore.
- The total cost of required parts (bearing kit plus spider plus any specialty tools you do not own) exceeds $120, and the machine is older than eight years.
If any of those conditions are true, a new washer in the $500–$700 range will give you a full warranty and less hassle than pushing forward with a flagged repair.
Decision Aid: Quick Pass/Fail Checklist
Use this checklist before buying any parts. Each item is a simple pass or fail check you can apply in minutes.
| Check | Pass / Fail |
|---|---|
| Machine is ≤ 8 years old | ☐ Pass ☐ Fail |
| Bearing kit cost ≤ $80 | ☐ Pass ☐ Fail |
| You have a bearing puller or press | ☐ Pass ☐ Fail |
| The drum spider is not cracked or corroded | ☐ Pass ☐ Fail |
| Total repair time fits within half a day | ☐ Pass ☐ Fail |
If you hit three or more “Fail” checks, consider buying a new washer. The cost of a new machine (often $450–$700) beats tackling a repair on a ten‑year‑old model that may have a corroded spider or failing tub seal.
Cost Comparison: Repair vs. Replace
| Machine Age | Repair Cost (Parts + Labor if hiring) | New Equivalent Cost | Verdict |
|---|---|---|---|
| 5‑year‑old mid‑range front‑loader | $250–$350 | $600–$800 | Worth repairing |
| 10‑year‑old budget top‑loader | $200–$300 | $400–$500 | Usually replace |
| 7‑year‑old high‑end machine (e.g., Miele) | $400–$600 | $1,500+ | Usually repair |
| 12‑year‑old standard washer | $250–$400 | $450–$600 | Replace |
Note: The biggest hidden cost is labor if you hire a pro. DIY only shaves $150–$250 off that bill.
Frequently Asked Questions
Can I replace just the seal without replacing the bearings?
Technically yes, but the bearings are already worn (that is why the seal failed). A new seal on old bearings will leak again within months. Replace both simultaneously.
How long does a DIY bearing replacement take?
For someone with basic mechanical experience, expect 3–5 hours. First‑timers often need a full day because of stubborn bearing extraction.
Is it normal for the drum to feel slightly wobbly after replacement?
No. If the drum moves more than 1/8 inch side‑to‑side at the opening, the new bearings are not seated properly or the spider is bent. Disassemble and check the fit.
