L68149 Trailer Axle Bearings Kit for 3500lb

Misakomo L68149 trailer axle bearing kit is a complete replacement set engineered to support 3500 lb spindles (1-1/16" to 1-3/8") and restore smooth, quiet wheel rotation.

This ready-to-install kit gathers the bearings, races, seals and hardware you need to service Spindle #84 and EZ-Lube style axles on 3500 lb trailers. Every component is manufactured from durable materials to resist wear, reduce vibration and extend the life of your hub assembly. The kit arrives in upgraded sealed packaging to keep parts clean and corrosion-free until installation.

What exactly is included and how does it match my trailer?

The kit is tailored for 3500 lb trailer axles with 1-1/16" to 1-3/8" spindle diameters (Spindle #84) and designed to work with EZ-Lube configurations. It contains both inner and outer bearings plus all the matching races, seals and mounting hardware so you can complete a hub job without scavenging parts.

• Bearings: L68149 (x2) and L44649 (x2)
• Races: L68111 (x2) and L44610 (x1)
• Grease seals 171255TB (1.719" I.D., x2), dust caps (1.98", x2)
• Cotter pins, rubber plugs, spindle nuts and washers included

How will these parts affect trailer performance and longevity?

Upgrading worn bearings and seals lowers friction and stabilizes the wheel spindle, which helps reduce heat, noise and wobble at highway speeds. The kit uses hardened components that are less prone to wear, helping the hub run cooler and stay aligned longer under load.

• Chrome steel bearings resist surface wear and maintain rolling efficiency
• Precisely matched races ensure even load distribution across the spindle
• New grease seals prevent contamination and preserve lubricant life
• Included dust caps and plugs protect internals from road debris and water

What should I know about installation and maintenance?

Installation follows standard hub overhaul procedures: remove the wheel and hub, replace bearings and races, fit new seals and repack with grease, then reassemble and torque the spindle nut to spec. The kit supplies the common hardware needed, but routine tools and a torque wrench are required for a safe, correct fit.

• Repack bearings with marine or wheel-bearing grease before assembly
• Inspect spindle for scoring or pitting; replace if damaged
• Use a bearing race driver to seat races without distortion
• Adjust endplay per manufacturer specifications and secure with cotter pin

What warranty and packaging protections come with the kit?

The kit is shipped with upgraded sealed bags for each component to resist rust and contamination during storage or transport. Misakomo backs the package with a 12-month warranty to cover defective materials or workmanship under normal use.

• Individual sealed bags for bearings, seals and small hardware
• Anti-corrosion packing helps long-term storage before installation
• 12-month warranty protects against defects in materials and build
• Customer support available for fitment and troubleshooting questions

Who is this for: This Misakomo L68149 kit is intended for trailer owners, DIY mechanics and fleet technicians working on single-axle or tandem trailers rated at 3500 lb that use Spindle #84 or EZ-Lube axles. It’s suited for those rebuilding hubs, replacing worn bearings and seals, or preparing trailers for heavy-use seasons where reliable, quiet rotation is important. If your axle specs match 1-1/16" to 1-3/8" spindle diameters and you want a full set of matched components in rust-resistant packaging, this kit provides a straightforward, cost-effective solution.
