GREPSPUD 5x4.5 Trailer Hub Kit for 3,500 lb Trailers — 1-1/16" to 1-3/8" Tapered Axle, Pre-assembled Hubs

GREPSPUD 5x4.5 trailer hub kits are complete replacement hub assemblies designed for 3,500 lb trailers with 1-1/16" to 1-3/8" tapered axles (EZ-Lube #84 spindle).

If you need a reliable hub rebuild or spare set for a dual-axle or single-axle trailer rated at 3,500 pounds, this GREPSPUD kit supplies two hubs plus the bearings, seals, studs, lug nuts and extra dust caps you need to reinstall wheels quickly. The hubs are pre-assembled with races, come with corrosion-resistant finishes, and are packaged with protective padding for safe transit.

Will these hubs fit my trailer axle and spindle type?

These hubs are specifically made for tapered axles with an inner diameter of 1-3/8" and an outer bearing ID of 1-1/16", matching EZ-Lube #84 spindles. They are not compatible with straight spindles or other bearing size combinations, so verify spindle measurements before ordering.

• Fits 3,500 lb trailers with 1-1/16" (L44649) outer bearing and 1-3/8" (L68149) inner bearing.
• Dust cap outer diameter: 1.98"; grease seal dimensions: 2.56" O.D. x 1.72" I.D.
• Bolt pattern: 5 on 4.5" with 1/2"-20 studs and included lug nuts.

What hardware and spare parts are included in the kit?

Each purchase contains two fully assembled hubs plus the mounting hardware and extra spares so you can complete a hub rebuild without sourcing additional parts. GREPSPUD provides extra dust caps and rubber plugs to keep you prepared for damage or loss during maintenance.

• Two hubs with bearing races installed and 1/2"-20 studs.
• Inner and outer bearings, two grease seals, lug nuts, and cotter pins where applicable.
• Extra: two spare dust caps and four rubber plugs included for emergencies.

How durable and rust-resistant are these hubs?

The hubs are constructed from heavy-gauge steel with protective coatings to withstand road exposure and reduce corrosion over time. Dust caps are zinc-plated and the hub bodies receive a black protective finish to extend service life under typical towing conditions.

• Black-coated steel hub bodies for corrosion resistance.
• Zinc-plated dust caps to resist rust at the bearing interface.
• Rubber seals and plugs to limit contamination and extend bearing life.

Any installation tips or special requirements I should know?

Because the dust caps are sized slightly larger for a secure fit, installation requires a light hammering with a wooden block or rubber mallet to avoid denting the cap. Bearings and seals are supplied, but proper packing of bearings with grease and torque to manufacturer specifications are necessary for safe operation.

• Use a wood block or rubber mallet to seat dust caps without distortion.
• Pack bearings with high-quality wheel grease before assembly.
• Torque wheel nuts and follow spindle end-play procedures as per trailer manufacturer.

Who this kit is for: The GREPSPUD 5x4.5 trailer hub kit is ideal for DIY trailer owners, maintenance shops, and fleet operators who maintain 3,500 lb trailers with EZ-Lube #84 tapered spindles. Buy this if you want a ready-to-install pair of hubs with spare dust caps and seals included, corrosion-resistant finishes, and packaging designed to protect components during shipping. If your spindle or bearing sizes differ, double-check measurements before purchase to ensure compatibility.
