How do I know this kit fits my trailer axle?

Match the bearing and race dimensions and spindle size to confirm fit. The kit is intended for 3,500 lb axles with spindles that accept 1-3/8" to 1-1/16" bearings; compare the listed IDs and ODs to your current parts or spindle specs.

• Inner bearing L68149: I.D. 1.378" for inner fit checks
• Inner race L68111: O.D. 2.362" to seat in the hub bore
• Outer bearing L44649: I.D. 1.063" matching the spindle journal
• Outer race L44610: O.D. 1.980" for hub seating

What parts are included in this two-hub service pack?

The kit bundles the bearings, races, grease seals and essential fasteners needed to rebuild two hubs. Parts are packaged as matched pairs so both left and right sides get the correct components for reliable assembly.

• 2 × Inner bearing L68149 and 2 × inner race L68111
• 2 × Outer bearing L44649 and 2 × outer race L44610

• 2 × tang washers and 2 × cotter pins for spindle retention

How do the grease seals and hardware affect maintenance?

The included double-lip grease seals and retention hardware keep lubricant in and contaminants out, extending bearing life when installed correctly. Using the correct seal size and replacing cotter pins and tang washers during service reduces the chance of premature wear.

• Grease seal 171255TB (10-19) fits Spindle #84 dimensions to prevent leaks
• Double-lip design offers improved protection against water and dirt
• Tang washers and cotter pins ensure secure castle nut retention

Can I install this myself, and what tools are typically required?

Experienced DIYers can install this kit with common automotive tools and a press or bearing driver for races. Proper installation technique—cleaning the hub, seating races squarely, and preloading bearings—is important for reliable operation.

• Basic tools: socket set, torque wrench, pliers, hammer and punch
• Press or bearing/race driver strongly recommended to avoid race damage
• Grease gun and high-temperature wheel bearing grease for packing bearings
