R&P Knowledge Hub
An idler hub supports the trailer wheel on non-braking axles and rotates on inner and outer tapered roller bearings. Proper fitment requires confirming bearing numbers, seal dimensions, and bolt pattern before installation.
Incorrect bearing sizing can lead to overheating and premature failure. Inspect the spindle for wear and verify race seating during assembly. Use proper torque specifications when installing lug nuts.
