Oacdiel Trailer Bearings Kit 2-Pack for 3,500 lb Axle — L68149 L44649 with Double-Lip Seals & Hardware

Oacdiel 2-Pack Trailer Bearings Kit delivers matching inner and outer bearings, races, double-lip grease seals, and hardware for a quiet, reliable 3,500 lb trailer axle repair.

This complete kit contains everything needed to service both sides of a single trailer hub: two inner bearings (L68149) with races, two outer bearings (L44649) with races, two 171255TB double-lip grease seals (spindle #84), plus cotter pins and tang washers. Parts are precision-made to the dimensions used on many 3,500 lb trailer axles and are intended to restore smooth rolling, reduce noise, and keep grease where it belongs.

What exactly comes in the kit and what are the key dimensions?

The package includes two of each bearing and race set for inner and outer positions, two grease seals, plus two cotter pins and two tang washers for spindle retention. Sizes match common trailer hubs so you can replace both sides at once.

• Inner bearing L68149: I.D. 1.378" (with inner race L68111, O.D. 2.362")
• Outer bearing L44649: I.D. 1.063" (with outer race L44610, O.D. 1.980")
• Grease seal 171255TB (10-19): double-lip, fits spindle #84, 1.719" x 2.565"
• Hardware: 2 cotter pins and 2 tang washers included

How does this kit improve trailer performance and maintenance?

Replacing worn bearings, races, and seals restores smooth rotation and minimizes heat and friction that lead to premature wear. The double-lip grease seals specifically prevent lubricant loss and keep contaminants out, reducing the frequency of maintenance.

• Precision bearings reduce vibration and audible noise during towing
• Durable races improve contact surfaces for longer service life
• Double-lip seals block water and road debris to preserve grease
• Complete hardware lets you reassemble the hub without sourcing extra parts

Will these parts fit my trailer axle and how do I confirm compatibility?

This kit is designed for trailer axles used on many 3,500 lb hubs with spindle #84 or spindles sized 1-3/8" to 1-1/16" where the listed bearing dimensions match. Always measure your current bearings, races, and seal to confirm exact matches before purchase.

• Check inner bearing I.D. of 1.378" and outer I.D. of 1.063"
• Verify inner race O.D. 2.362" and outer race O.D. 1.980"
• Confirm grease seal size 1.719" x 2.565" for spindle #84
• If dimensions match, the kit services both sides of a single axle hub

How easy is installation and what tools will I need?

Installation follows standard hub service procedures: remove the hub, extract old bearings and races, press or drive in new races, pack bearings with grease, install bearings and seals, then torque and secure with the provided hardware. The kit supplies the fasteners; typical hand tools and a bearing press or driver are recommended.

• Tools: socket set, torque wrench, bearing packer or grease gun, press or race driver
• Steps: remove hub, replace races, pack bearings with grease, install seals and retainers
• Time: average DIY hub service for one axle side about 45–90 minutes
• Hardware included prevents last-minute parts runs
