WPS Trailer Axle Bearing Kit 3,500 lb — Set of 2 for #84 Spindle with L68149/L44649 and 10-19 Reinforced Double-Lip Seals

WPS 3500# trailer axle bearing kit provides the inner and outer bearings, races, and reinforced double-lip grease seals needed to service two hubs on #84 spindles.

This complete set contains the matched bearing and race pairs plus upgraded grease seals for two wheel hubs on 3,500 lb trailer axles. The kit bundles L68149/L68111 inner bearings and races, L44649/L44610 outer bearings and races, and 10-19 double-lip seals (171255TB) with a reinforcement spring behind the lip to help retain grease and resist contamination. It’s supplied as a pair so you can maintain both sides of the axle at once, saving time and ensuring compatible tolerances across the wheel ends.

Which parts are included and how do they fit together?

This kit supplies the inner and outer bearing/race combinations plus two double-lip grease seals for each hub position across both sides of a single axle. Inner bearings (L68149) pair with inner races (L68111), while outer bearings (L44649) pair with outer races (L44610). The seals are sized 10-19 and include a reinforcement spring to back the lip.

• 2 inner bearings (L68149) and 2 inner races (L68111)
• 2 outer bearings (L44649) and 2 outer races (L44610)
• 2 double-lip grease seals 10-19 (171255TB) with reinforcement spring
• Designed for #84 spindle applications on 3,500 lb axles

How do the double-lip seals improve grease retention?

The seals in this kit feature a double-lip design with an added spring behind the primary lip to maintain contact and pressure. That construction reduces the chance of grease escaping around the spindle and helps block water, dirt and road grime from reaching the bearings. Seals are sized to fit the hub bore and run concentric with the spindle when installed correctly.

• Double-lip profile for primary and secondary barriers
• Reinforced spring supports continuous lip contact
• Helps prevent external contamination and grease loss
• 10-19 sizing compatible with specified hub/spindle geometry

Can I use this kit on any trailer with a 3,500 lb axle?

Use this kit on trailers that have 3,500 lb axles fitted with #84 spindles and matching hub bores for 10-19 seals. Verify your existing part numbers or measure spindle and hub dimensions before installation to ensure compatibility. If your bearings, races or seals have different part numbers or sizes, choose a kit that matches those specifications instead.

• Intended for 3,500 lb trailer axles with #84 spindles
• Compare spindle/hub measurements and part numbers first
• Sold as a two-hub set for left and right service at once

What service tasks is this kit intended for and what tools are required?

This kit is intended for bearing replacement, race installation and seal renewal when servicing trailer hubs. Typical tasks include hub disassembly, bearing inspection, race seating, greasing, and seal installation. Common tools include a hub puller or press, bearing race driver, torque wrench, grease gun, and basic hand tools for axle hardware.

• Hub removal and bearing inspection
• Race installation with driver or press tool
• Seal installation using an appropriate driver to avoid lip damage
• Final bearing preload and proper torqueing of axle nut

Who this is for: This WPS kit is aimed at DIY trailer owners, fleet maintenance crews, and small repair shops performing routine hub maintenance on 3,500 lb trailers with #84 spindles. It’s useful when replacing worn bearings and races or renewing seals to protect freshly greased bearings. Always confirm fitment against your current spindle and hub measurements before purchase and follow manufacturer-recommended service procedures during installation.
