• Excessive shaft play in the manual gearbox
• Rough shifting caused by bearing wear or damage
• Metal contamination from a deteriorated taper bearing
• Loss of proper gear support in the transmission assembly

Installation Notes and Tips

• Verify bore, outside diameter, and width before installation.
• Confirm transmission code and position: right, front outer, left, or inner, as listed for the vehicle.
• Inspect the shaft, cup, and surrounding transmission components for wear before assembly.
• Use proper bearing installation tools to avoid damaging the cone or cup surfaces.
• For fitment-specific service, confirm the vehicle and transmission combination before ordering.
