Lwlusup Trailer Axle Bearing Kit Pack of 4 for L68149/L44649 – 3500 lb, seals & hardware

This Lwlusup Pack of 4 Trailer Axle Bearings Kit is built to refresh or repair trailer hubs that use the L68149/L44649 bearing set. The kit groups all wheel-end service parts you need — inner and outer bearings and races, double-lip grease seals sized for spindle #84, tang washers and cotter pins — so installation is straightforward and you won’t be missing a critical component during maintenance.

Which trailer axles and capacities does this kit fit?

This bearing kit is designed for trailer axles that accept inner/heavier L68149 and outer L44649 bearings and that are rated up to 3,500 pounds. Confirm spindle and hub dimensions on your trailer before ordering to ensure correct fitment.

• Compatible with 1-3/8" to 1-1/16" 3500 lb trailer axles
• Inner bearing L68149 with 1.378" I.D.
• Outer bearing L44649 with 1.063" I.D.
• Includes seals sized for spindle #84 (1.719" x 2.565")

What parts are included and why they matter?

The kit supplies matched bearing and race pairs plus seals and fasteners so wheel-end geometry and clearance are preserved. Using matched components reduces the risk of premature wear and helps maintain safe, smooth bearing operation after service.

• 4 inner bearings L68149 and 4 inner races L68111 (OD 2.362")
• 4 outer bearings L44649 and 4 outer races L44610 (OD 1.980")
• 4 double-lip grease seals 171255TB (10-19) for reliable lubrication retention
• 4 tang washers and 4 cotter pins to secure the assembly

How does the grease seal and hardware affect maintenance?

The double-lip grease seals included help keep grease in and contaminants out, extending bearing life between service intervals. The tang washers and cotter pins provide a secure, conventional locking method for many spindle/hub systems.

• Double-lip seal design reduces water and dirt ingress
• Grease seal dimensions match spindle #84 for straightforward replacement
• Tang washers and cotter pins restore factory-style retention and safety

How should I verify fitment before installation?

Measure the inner and outer bearing I.D./O.D., the race O.D., and your spindle diameter or refer to your hub manual. Cross-checking these dimensions prevents returns and ensures you have the correct seals and bearings for your trailer hub.

• Inner bearing I.D.: 1.378" (L68149)
• Inner race O.D.: 2.362" (L68111)
• Outer bearing I.D.: 1.063" (L44649); outer race O.D.: 1.980" (L44610)
• Seal: 171255TB (10-19), 1.719" x 2.565" fits spindle #84

Who this is for: This Lwlusup bearing kit is intended for trailer owners, DIY mechanics, and service shops that need a complete wheel-end refresh for 3,500 lb axles using L68149/L44649 bearings.
