Understanding the Problem
When a Kenmore 300 Series washer develops worn tub bearings or a damaged drive shaft (spindle), you’ll typically hear loud rumbling or grinding during spin, feel heavy vibration or wobble, and sometimes notice the washer won’t drain or complete spin cycles. Bearing failure usually starts quietly and gets progressively worse as the seals fail and water corrodes the bearing surfaces. Replacing the bearings and shaft (or the complete bearing kit/spindle assembly) requires removing the washer cabinet, unbolting the outer tub, and pressing out the old bearings and seals. Because many components interconnect (seal, bearing, hub, spindle), a full bearing kit plus the shaft or hub assembly is commonly recommended to restore reliable operation and prevent rework.
Common Symptoms
Loud rumbling or grinding during spin, excessive vibration or wobble, visible tub play when pushed/pulled, leaking oil/grease near the tub base, and spin/drain failures.
Common Causes
- Water intrusion past a worn tub seal causing bearing corrosion and wear
- Normal wear from age and heavy loads (overloading repeatedly)
- Damaged or bent shaft (spindle) from impact or prolonged operation with bad bearings

Helpful Repair Tip
To confirm bearing or shaft failure: rotate the tub by hand (with power off and lid open). Feel for roughness or grinding and check for vertical play by pushing/pulling the inner tub. Excessive play or rough rotation indicates bearings or the spindle are bad.
Frequently Asked Questions
How long does a shaft and bearing replacement take?
For a competent DIYer with basic tools it typically takes 2–4 hours. A professional repair technician can often complete the job in 1–2 hours. Time varies by model, your experience, and whether additional parts (hub, clutch, seals) need replacing.
Can I replace just the bearings or do I need to replace the whole shaft or tub?
If bearings and seals are worn but the shaft and hub are not damaged, replacing the bearing kit and seals is usually sufficient. However, if the spindle is bent, corroded, or the hub/bearing race is damaged, you'll need the shaft (spindle) assembly or hub replaced as well. Inspect all mating surfaces carefully during disassembly and replace any parts with scoring, pitting, or excessive wear.
