Frequently Asked Questions (FAQs)

 

Q: Will this hub work on a trailer without brakes (i.e. as an idler)?

A: Yes — though marketed as an “idler hub kit,” it’s fully compatible with trailer systems that include brakes because it uses the same axle and bearing standards. Just ensure your drum, backing plate, or brake hardware matches your axle and brake setup.

Q: Can I use this hub on a heavier trailer or higher capacity axle?

A: No. This kit is specifically rated for 3,500 lb axles. Using it above its rating could lead to premature failure or safety issues.

Q: Is the grease sufficient for long service intervals?

A: Yes — the bearings arrive pre-lubed with a quality lithium-based grease suitable for typical trailer conditions. However, always check and re-grease per maintenance schedules for best longevity.

Q: What parts are included in the kit?

A: The kit contains: hub (H-545-07), inner & outer bearings, races, grease seal, dust cap, rubber plug, lug nuts, slotted nut, washers, cotter pin, tang washer.

Q: What does the warranty cover, and how do I make a claim?

A: The 1 Year Limited Warranty covers manufacturing defects — it does not cover damage due to misuse, accident, corrosion, or improper installation. To make a claim, you’ll need proof of purchase and photos/details of the defect.
