What It Helps Fix

  • Noise from worn differential bearings
  • Excessive play in axle or differential components
  • Rough bearing surfaces found during teardown
  • Heat-related wear in tapered roller bearing races
  • Loss of proper bearing preload or running clearance

Installation Notes and Tips

Inspect the matching cone, bearing rollers, and related differential components before installation. Replace the cone and cup as a matched service set when wear is present, and verify correct seating, preload, and lubrication during assembly. Confirm application details by vehicle service information before ordering Timken 34478 for your repair.
