WESTERNPRIME 3500 lb Trailer Tandem Axle Bearing Kits (Set of 4) 1.719" I.D. Seals — L68149/L44649 Complete Repair Kit

Four complete bearing kits from WESTERNPRIME provide inner and outer races plus double-lip grease seals sized for 3500 lb tandem trailer axles with a 1.719" inner diameter.

Keep your trailer hubs running smoothly and protect bearings from water and road grime with this consolidated set. Each package contains the inner and outer bearing/race pairs required for two axles (four hubs total) and double-lip grease seals designed with a springed lip to retain lubricant. That combination simplifies maintenance, reduces parts hunting, and supplies the compatible components for spindles specified as #84.

What parts are included and how do they match my axle?

This set contains four inner bearing/race pairs (L68149/L68111), four outer bearing/race pairs (L44649/L44610), and four double-lip grease seals (10-19, 1.719" I.D.). The bearings and races correspond to common 3500-lb trailer hub assemblies, and the seals fit hubs that accept a 1.719" inner diameter part. Always verify your hub and spindle numbers before installation to confirm fit.

• Inner bearings and races: L68149 / L68111 (x4)
• Outer bearings and races: L44649 / L44610 (x4)
• Seals: double-lip 10-19, 1.719" I.D., with springed lip (x4)

How does the double-lip grease seal help during towing?

The double-lip design provides two barriers against contaminants while the internal spring behind the sealing lip helps maintain contact and keep grease inside the hub. This reduces the chance of premature wear from moisture or dirt exposure and helps prolong bearing life when properly greased and installed. It’s not a substitute for correct maintenance, but it improves protection compared with single-lip seals.

• Two sealing surfaces for improved contamination resistance
• Reinforcing spring keeps consistent lip pressure
• Helps retain lubricant inside the hub during operation

What tools and steps are needed to replace these bearings and seals?

Basic hub servicing requires a jack, jack stands, socket set, bearing packer or grease gun, bearing race driver or press, and torque wrench. Remove the wheel and hub, pull old bearings and races, install the new races (driven square and flush), pack bearings with high-quality wheel grease, fit bearings, and install the new seals. Torque the axle nut per manufacturer spec and check for correct endplay and smooth rotation before the first trip.

• Essential tools: jack, stands, sockets, race driver/press, grease packer
• Step highlights: remove hub, replace races, pack bearings, press seal, set torque
• Confirm spindle type (#84) and follow vehicle-specific torque/endplay values

Will these kits work for routine maintenance or emergency replacements?

Yes — the kit covers both planned overhauls and roadside repairs when you have time and tools. Having a complete set on hand makes it faster to perform scheduled bearing service or to address bearing failures by replacing both bearings, races, and seals together. For emergencies, ensure you have the right tools and, if unsure, consult a qualified technician to avoid improper installation.

• Useful for scheduled hub service on 3500-lb axles
• Provides matching parts to replace worn bearings and seals at once
• Carry spares for faster roadside fixes when equipped with tools
