What parts are included and why does each matter?

The kit contains the bearings, races, seals and mounting hardware required to rebuild a pair of hubs. Each component plays a role in maintaining wheel alignment, bearing preload and keeping grease in while contaminants stay out.

How do I know this kit fits my trailer axle?

Match the bearing and race dimensions or confirm your spindle number (spindle #84) to ensure compatibility. This kit is designed for trailers with axles rated up to 3,500 lbs and spindles that accept 1-3/8" to 1-1/16" bearing sizes.

• Check inner bearing ID 1.378" (L68149) against your current bearing.
• Confirm outer bearing ID 1.063" (L44649) for the outer position.
• Verify grease seal size 1.719" x 2.565" for spindle #84 fitment.
• Cross-reference your axle rating — intended for 3,500 lb trailer axles.

What tools and steps are needed to replace these bearings?

Basic wheel hub service tools are sufficient: a jack, jack stands, bearing packer or grease, socket set, bearing puller or press, and a torque wrench. The process involves removing the wheel and hub, extracting old bearings and races, installing new races, packing bearings with grease, and reassembling with correct preload.

• Tools: jack, stands, sockets, hammer/dolly, bearing driver or press, grease packer.
• Steps: remove wheel/hub, remove old bearings/seals, press in races, grease and insert new bearings, install seals and secure with tang washer and cotter pin.
• Tip: replace both sides at once for even performance and longer service life.

How durable is this Lwlusup kit and what maintenance does it need?

The bearings and races are manufactured to standard tolerances suitable for trailer use; the included double-lip grease seals reduce grease loss and keep contaminants out. Regular inspection and periodic repacking or replacement as part of scheduled trailer maintenance will extend service life.

• Durability depends on proper installation, correct torque/preload, and regular greasing.
• Inspect seals and bearings annually or every 12 months/12,000 miles, whichever comes first.
• Replace seals if torn and bearings if worn, pitted, or noisy under load.

Who is this for: This Lwlusup Pack of 2 Trailer Axle Bearings Kit is aimed at trailer owners, DIY mechanics, and service shops that need a ready-to-install set for 3,500-lb axles using spindle #84 or equivalent.
