LUXTRKSTO 5x4.5 Trailer Hub Kit for 3500 lb Axles — Tapered 1-1/16" to 1-3/8", Pre-greased Bearings

If you need a reliable hub replacement for a 3500 lb trailer axle, the LUXTRKSTO 5x4.5 hub kit gives you the core components in one box so you can swap out a worn hub quickly and confidently. The assembly arrives pre-lubricated and pre-assembled where possible, reducing installation time and simplifying maintenance. Built from carbon steel with a protective coating, the hub aims to resist corrosion and provide consistent function under towing conditions.

How do I confirm this hub fits my trailer axle?

Measure both bolt pattern and spindle diameter before ordering. The hub is made for a 5-on-4.5 bolt pattern and fits tapered spindles measuring between 1-1/16" and 1-3/8".

• Check lug pattern: 5 lugs on a 4.5" circle (measure from outermost hole to center).
• Verify spindle taper range: 1-1/16" to 1-3/8" diameters.
• Compare bearing numbers: L44649 outer and L68149 inner.

What comes in the LUXTRKSTO hub kit and what’s pre-installed?

This kit contains all hardware needed to mount the hub without extra trips to the parts store. Bearings are installed and pre-lubricated to limit initial wear and to protect against rust during storage and first use.

• 1x 3500 lb 5x4.5 hub assembly
• Inner bearing L68149 and outer bearing L44649 (pre-greased)
• Grease seal, spindle nut, washer, dust cap with rubber plug, cotter pin, and five lug nuts

How difficult is installation and what should I watch for?

Installation is straightforward for anyone familiar with basic trailer wheel service, but attention to fitment and torque is essential. Some surfaces — such as the dust cap edge — may require light grinding to match your spindle taper for a snug fit.

• No assembly of internal parts required — bearings pre-installed and lubed.
• Trim dust cap OD if needed to achieve proper seating on tapered spindle.
• Follow torque and cotter pin procedures to secure spindle nut and prevent loosening.

How does the kit perform in corrosion resistance and longevity?

The hub and components use carbon steel plus a painted surface treatment to slow corrosion in normal trailer use. Bearings are precision-made to limit friction and noise, and the thicker grease seal reduces leakage risk.

• Painted finish to resist environmental wear and rust.
• Pre-lubricated bearings to protect during initial service life.
• Thicker grease seal to help keep contaminants out of bearings.

Who is this for: This hub kit is aimed at trailer owners, repair shops, and DIY mechanics who need a full, ready-to-install replacement for 3500 lb axles with a 5x4.5 bolt pattern.
