Our take on the 3500 lb Galvanized Trailer Axle Hub – Pre-Greased – 5 on 4.5" – Complete Hub Kit

This is a complete 3,500 lb trailer hub assembly with a 5 on 4.5" bolt pattern, galvanized for corrosion resistance in marine and outdoor use. It arrives pre-greased with Mobil grease and pre-pressed races, so it installs without packing bearings or seating races yourself. The 1/2"-20 studs and included dust cap with rubber plug match common 3,500 lb idler and brake hubs, but the cap is not waterproof and the kit is a single hub, not a pair. It suits boat trailer owners and anyone replacing a rusted or worn hub on a light utility or camper trailer.

About the 3500 lb Galvanized Trailer Axle Hub – Pre-Greased – 5 on 4.5" – Complete Hub Kit

This is a 3500 lb galvanized trailer axle hub for wheels with a 5 on 4.5" bolt pattern. The galvanized finish resists corrosion, so the hub suits boat trailers, utility trailers, cargo trailers and other outdoor or high-moisture use.

The hub comes pre-assembled and pre-greased with Mobil grease. The inner bearing and race and the wheel studs are already pressed in. The kit includes the outer bearing, seal, washers, nuts and cap needed to install it.

It fits most 3500 lb trailer axles that use the L68149 inner bearing and L44649 outer bearing. The dust/grease cap is not waterproof.

It is rated for 3,500 lb axles and uses the common 5 on 4.5" bolt pattern with 1/2"-20 studs. Check your spindle size and wheel pattern before ordering.

No. The hub comes pre-greased with Mobil grease and the inner races are already pressed in. Install it and go.
Is it waterproof for boat trailers?
No. The dust cap has a rubber plug but is not waterproof, so check and re-grease after dunking.
