GREPSPUD 5x5 Trailer Hub Kit for 3500 lb Axles — Pair, 1-1/16 to 1-3/8 tapered spindle, Black-coated

If your trailer uses a 5-on-5" bolt pattern and a tapered spindle (spindle #84, EZ-Lube compatible), this GREPSPUD kit gives you two fully equipped hubs plus spare dust caps and plugs so you can complete both sides without hunting for extra parts. The set targets 3500 lb axles and includes the common inner and outer bearing sizes, grease seals and all mounting hardware needed for a straightforward swap.

How do I know these hubs match my trailer axle?

Start by confirming three details: the bolt pattern (5 on 5"), the axle capacity (3500 lb), and the tapered spindle diameters (outer bearing I.D. 1-1/16" and inner bearing I.D. 1-3/8"). This kit is built for spindles like #84 and EZ-Lube style axles.

• Bolt pattern: 5 on 5" with 1/2"-20 studs
• Outer bearing: L44649 (I.D. 1-1/16")
• Inner bearing: L68149 (I.D. 1-3/8")
• Grease seal sizes: 2.56" O.D., 1.72" I.D.

What parts and extras come in the kit?

The GREPSPUD kit arrives as a complete pair of hubs and includes every fastener required to mount and secure them. It even supplies extra dust caps and rubber plugs so you have spares for roadside needs or future maintenance.

• 2 hubs (5x5" bolt pattern) and 2 L44649 outer bearings
• 2 L68149 inner bearings and 2 grease seals
• 10 lug nuts, 2 spindle nuts, cotter pins, washers, and 4 dust caps
• Additional 2 dust caps and 4 rubber plugs as backups

How durable and rust resistant are these components?

GREPSPUD uses high-quality steel and rubber for the hubs and hardware, with surface treatments to slow corrosion and protect against wear. The hub bodies have a black coating while dust caps are zinc-plated to resist rust; proper installation and periodic greasing will extend service life.

• Black-coated hub surface for corrosion resistance
• Zinc-plated dust caps to reduce rusting
• Durable steel and rubber parts designed for towing loads
• Packaging protects parts during shipping to prevent damage

Are there any special installation notes I should know?

Installation is typical for tapered axle hubs, but note the dust cap is intentionally slightly oversized to ensure a tight fit. Use a wood block and rubber mallet or hammer to seat the cap without deforming it, and follow proper bearing preload and cotter-pin procedures for safety.

• Knock dust cap in with wood block or rubber mallet to avoid dents
• Pack bearings with grease and torque spindle nut to spec
• Install cotter pin and check hub end-play after assembly
• Keep spare dust caps and plugs on hand for quick roadside fixes

Who is this for? This GREPSPUD 5x5" trailer hub kit is suited to DIY trailer owners, fleet managers and repair shops replacing worn hubs on 3500 lb trailers with tapered spindles. If you want a full, value-packed pair of hubs with the required bearings, seals and mounting hardware — plus extras for emergencies — this kit reduces trips to multiple suppliers and simplifies the replacement job.
