Understanding the Problem
What the drum support assembly is and why it fails: The drum support assembly (rear drum support/ bearing housing) holds the rear of the dryer drum and provides a smooth bearing surface for the drum to spin on. On many GE dryers this plastic or metal support includes a bushing or bearing surface and mounts to the rear bulkhead. Over time the bearing surface can wear, crack, or the mounting tabs can break — causing noise, scraping, drum wobble, and premature belt wear. Step-by-step diagnostic and repair instructions: 1) Verify the symptom: With the dryer off and unplugged, open the dryer door and spin the drum by hand. Note any roughness, scraping, grinding, or excessive side-to-side play. Listen for a metallic scrape or rumble. 2) Access the drum: Unplug the dryer and move it away from the wall. Remove the lint screen and then remove the top panel (usually screws at the back). On many GE models remove the front panel/door (unscrew hinge screws and the two upper front screws). Release the belt from the idler and pull the drum forward to inspect the rear bearing/support. 3) Inspect the drum support assembly: Look at the rear bulkhead where the drum rides. If the support is cracked, the bearing surface is grooved, or the drum shaft is contacting metal/plastic, the support assembly needs replacing. Also inspect the drum shaft and rear felt seals for wear. 4) Check related components: While you have the drum out, check the idler pulley, motor pulley, drum rollers (if present), and belt for wear—replace any worn parts. A failing roller or seized idler can put extra stress on the drum support. 5) Remove the old support assembly: With the drum removed, unscrew the mounting screws that hold the drum support assembly to the rear bulkhead (these are typically 4–6 screws). Remove any clips or brackets and pull the old unit out. Clean lint and debris from the area. 6) Install the new assembly: Position the replacement drum support assembly (align tabs and bolt holes), secure all mounting screws snugly, and ensure the bearing/bushing is seated properly. If the assembly includes a rear bearing insert make sure it is flush and rotated correctly. 7) Reassemble the dryer: Reinstall the drum, loop the belt around the drum and motor pulley, move the belt over the idler and check belt tracking. Reinstall the front panel/top and the lint screen. Plug the dryer back in. 8) Test run: Run the dryer empty and listen — the noise should be gone and the drum should turn smoothly without axial play. Check for rubbing or misalignment. Safety note: Always unplug the dryer before starting any repairs. If you're unsure about disassembly or dealing with gas lines (for gas dryers), stop and call a qualified technician.
Common Symptoms
Loud rumbling or scraping noise during spin, visible drum wobble or misalignment, belt wear or unusual squeal, and uneven drying due to drum not turning freely.
Common Causes
- Worn or grooved bearing/bushing inside the support assembly
- Cracked or broken support housing or mounting tabs
- Foreign objects or lint buildup causing friction on the drum shaft

Helpful Repair Tip
With the drum removed, spin the replacement assembly's bearing by hand — it should feel smooth with no rough spots. Excess side-to-side play at the drum shaft indicates the support is worn.
Frequently Asked Questions
Can I replace the drum support assembly myself?
Yes — if you're comfortable unplugging the dryer and removing the front/top panels, you can replace the support assembly yourself. Follow the steps above, keep track of screws, and always unplug the unit first. If the dryer is gas-equipped or you encounter rusted fasteners or broken brackets, consider a pro.
How long does the replacement take?
For a homeowner with basic tools expect 45–90 minutes. Faster if you're experienced; longer if additional worn parts (rollers, belt, idler) also need replacement.
