This AB Tools 42490 sealed wheel hub bearing kit is designed for owners of Ifor Williams trailers manufactured after 1997, providing a complete and economical solution for replacing worn or damaged wheel hub bearings on various heavy-duty trailer types. The kit offers a durable, back-to-back cone set with a split inner raceway and a double-row sealed bearing, ensuring reliable performance. A potential caveat is that it is specifically designed for Ifor Williams models from 1997 onwards, so compatibility with other brands or older models should be carefully verified.

This listing is for two complete bearing kits, meaning you receive enough components to service one full wheel hub (two sides).
The 'one-shot' hub nut is designed to be tightened to a specific torque and is typically not meant to be reused or loosened significantly once set. It ensures proper bearing pre-load. It should be replaced with the new one provided in the kit.
This kit is specifically designed for Ifor Williams trailers and axles from 1997 onwards. While dimensions might sometimes overlap, it's not guaranteed to fit older models, and using it may compromise safety.
The external diameter of the sealed bearing is 76mm.
No, the bearings are factory sealed and pre-lubricated for their lifespan. Routine greasing is not required for the bearing unit itself.
This is an alternative aftermarket part that serves as a direct replacement for Ifor Williams part number 42490.
The kit is suitable for Ifor Williams models including CT, HB, DP, GD, LM, LT, TA, and TT, manufactured after 1997.
Ensure the one-shot hub nut is not overtightened, which can pre-load the bearing excessively. Loosen slightly and re-torque to the specified value. Check for any debris trapped during installation.
Verify that the bearing and any internal seals are seated perfectly flush within the hub. An improperly seated bearing can prevent the hub cap from fitting flush.
Double-check that all components (bearings, circlips, hub nut) were installed correctly and simultaneously as per the instructions. Ensure the hub nut is torqued to the correct specification.
Ensure the correct parts were used and installed according to the instructions. Verify the trailer's load capacity is not exceeded, as this can lead to premature bearing failure.
Compatibility:
This kit is specifically designed for Ifor Williams trailers and axles manufactured from 1997 onwards. It is confirmed to fit models including CT, HB, DP, GD, LM, LT, TA, and TT series. Always verify your trailer's axle and bearing specifications against the kit's dimensions (Internal Diameter: 42mm, External Diameter: 76mm, Depth: 39mm) before purchase to ensure a correct fit, especially if you have a non-Ifor Williams trailer or an older Ifor Williams model.
Setup & Installation:
Care:
While these bearings are sealed, periodic visual inspection is recommended. Check for any signs of damage or grease leakage during routine trailer maintenance. Although designed for low maintenance, prolonged exposure to extreme conditions may warrant closer inspection. No routine greasing is required for the sealed bearing unit itself.
