Symptoms
- A hum, wheel play, and uneven tire wear — symptoms similar to a bearing fault.
What's included
- It is replaced for impact deformation, a worn bearing seat or stripped threads. Symptoms resemble a faulty bearing: humming, wheel play and uneven tyre wear. We therefore identify the source precisely before dismantling the assembly. Care is essential: a stub axle installed out of alignment causes runout and quickly damages a new bearing. We check seating and tightening torques, then verify free wheel rotation and inspect the brake mechanism exposed during dismantling.
Additional checks
- Condition of the bearing seat and axle threads
- Axle seating and tightening torques
- Free wheel rotation and brake mechanism condition
Why it matters
A stub axle fault and a bearing fault look similar, so the actual source is pinpointed first. An axle installed at an angle causes runout and sharply shortens a new bearing's service life.
More details
A stub axle (spindle) is the shaft the rear wheel hub sits on. It's replaced after impact deformation, wear of the bearing seat, or stripped threads. The symptoms resemble a bearing fault: hum, wheel play, uneven tire wear — so we first pin down the exact source of the problem before disassembling the unit. The job requires precision: a spindle installed at an angle causes runout and quickly kills a new bearing. We check the fit and tightening torques, and after assembly we check the wheel spins freely and inspect the brake mechanism, which becomes accessible during disassembly.
