GREPSPUD 5x4.5 Trailer Hub Kit for 3500 lb Trailers — 1-1/16" to 1-3/8" Tapered EZ-Lube Spindle, Pre-Greased Bearings

GREPSPUD 5x4.5 Trailer Hub Kit is a complete, pre-lubricated replacement hub assembly built to fit 3500 lb trailers with 1-1/16" to 1-3/8" tapered EZ-Lube axles (not for straight spindles).

This kit supplies everything needed to restore a trailer wheel end: hubs with pre-installed bearings and seals, grease-ready components, dust caps, and mounting hardware. Designed for EZ-Lube #84 spindle applications that accept L44649 outer bearings and L68149 inner bearings, the assembly arrives corrosion-resistant and ready for installation so you can minimize downtime and avoid a parts run.

Will this hub kit fit my trailer axle and bearings?

Confirm fit by checking your axle taper and bearing part numbers. This GREPSPUD kit is engineered for 1-1/16" to 1-3/8" tapered EZ-Lube spindles and matches the L44649 outer and L68149 inner bearings.

• Fits 3500 lb trailer axles with EZ-Lube #84 spindles only.
• Compatible with L44649 (outer) and L68149 (inner) bearings.
• Not compatible with straight spindles — measure spindle taper before ordering.
• Wheel bolt pattern: 5 x 4.5 (measure from outermost hole edge to center of opposite hole).

How much assembly is required and what comes prepped?

The hubs come with bearings and grease seals pre-assembled and lubricated, so most of the time you can install directly onto the spindle. Remaining hardware is included and organized to speed up installation.

• Bearings and seals pre-greased and mounted in the hub.
• Included: dust caps, mounting nuts/bolts, and any small hardware needed.
• Simple tools required: hammer or rubber mallet, wood block for dust cap seating.
• Follow torque and bearing preload steps specific to your axle for safe operation.

What durability and corrosion protection does this kit offer?

GREPSPUD hubs are manufactured from heavy-duty steel with a protective black coating, and dust caps are zinc-plated to resist rust. Bearings are precision-made for reduced friction and longer service life under typical towing conditions.

• Black-coated hub surfaces for corrosion resistance and wear protection.
• Zinc-plated dust caps add extra rust protection at the hub face.
• High-precision bearings designed for low noise and smoother rotation.
• Sturdy packaging minimizes transportation damage to preserve part integrity.

Are there any special installation notes or tips?

The axle dust cap is intentionally slightly oversized; seat it with a wood block and hammer or a rubber mallet to avoid denting. Verify bolt pattern measurements and spindle compatibility before beginning work to prevent delays.

• Use a wood block or rubber mallet to drive the dust cap in place without deformation.
• Measure 5x4.5 bolt pattern from outer hole edge to opposite hole center to confirm fit.
• Check spindle type (tapered EZ-Lube #84) to ensure correct application.
• Inspect grease and bearing preload after first short trip to confirm proper seating.

Who is this for: The GREPSPUD 5x4.5 Trailer Hub Kit is ideal for DIYers, fleet maintainers, and weekend haulers who need a reliable, ready-to-install wheel hub assembly for 3500 lb trailers with tapered EZ-Lube spindles. If you maintain a utility trailer, boat trailer, or small travel trailer and need a corrosion-resistant, pre-lubricated hub with correct bearing fitment, this kit provides the parts and protection required to get back on the road quickly.
