Genuine OEM Replacement Part

Drum Grinding or Wobbling? Replace the Tub Ball Bearing Before It Destroys Your Washer

Part# 4280FR4048N 30mm × 72mm × 19mm Fits LG WM Series Front-Load

A failed tub ball bearing doesn't just make noise — it allows the drum to wobble off-axis, accelerating seal wear, damaging the spider arm, and eventually seizing the motor. Part 4280FR4048N is the OEM LG tub ball bearing that supports the inner rear of the drum. Replacing it at first sign of grinding restores smooth, quiet operation and prevents a minor repair from becoming a full drum replacement.

Symptoms of a Failing Tub Bearing

  • Loud grinding, rumbling, or roaring noise during spin cycle
  • Drum wobbles or feels loose when rotated by hand
  • Excessive vibration, especially at high spin speeds
  • Leaking from the rear tub seal (bearing failure accelerates seal wear)
  • UE or OE error codes caused by drum imbalance

💡 Pro Tip — Replace the Tub Seal at the Same Time:
The rear tub seal (4036ER4001B) and tub bearing work as a pair — a worn bearing accelerates seal failure and vice versa. Since you're already pulling the drum, replacing both in one labour visit saves your customer a costly callback. Also inspect the spider arm for stress cracks before reassembly.

Installation Notes

  • Skill Level: Advanced — requires full drum disassembly and tub splitting
  • Always disconnect power before beginning any repair
  • Drain and disconnect water supply lines before disassembly
  • Use a bearing press or appropriate driver to seat the bearing flush — do not hammer directly on the race
  • Inspect the tub seal, spider arm, and drum shaft for wear before reassembly
  • Torque all tub bolts to manufacturer spec; uneven torque causes premature bearing failure
