R&P Service Insight | Confirm Before Installation
Inspect the spindle for scoring, corrosion, heat damage, and bearing-seat wear before installing replacement components. Compare the original bearing numbers and oil-seal fitment, and follow the axle manufacturer's lubrication, bearing adjustment, and wheel-fastener torque procedures.
The kit's component list identifies bearings but does not separately list bearing cups or races. Verify whether additional components are required before beginning service.
