R&P Service Insight
Idler hubs are commonly replaced after bearing wear, seal failure, grease contamination, or damage to the original hub body and running surfaces.
- Bearing Wear: Worn bearings create heat, noise, and looseness that can damage the hub
- Seal Failure: A failed seal allows grease loss and contamination inside the hub
- Service Convenience: A pre-greased kit helps speed up replacement when all matching parts are needed together
