Everything you need to repack one trailer hub on a 5,200 lb capacity Lippert, Dexter, or Al-Ko axle -- matched bearings, cups, grease seal, and cotter pin, all in one kit. Stop sourcing parts individually and get back on the road with confidence.
Wheel bearing maintenance is one of the most important -- and most overlooked -- service items on any towed trailer or RV. Neglected bearings run hot, wear unevenly, and can fail at highway speed. Lippert's 333949 kit takes the guesswork out of a bearing service by bundling every component needed for one full hub repack into a single, matched set.
This kit is engineered to fit the 5,200 lb axle assemblies produced by Lippert, Dexter, and Al-Ko -- three of the most common axle brands found under travel trailers, fifth wheels, and utility trailers. If your rig rides on one of these axles and you're due for a bearing repack (or you've heard that telltale growl), this is the kit to grab.
Includes LM67048 outer bearing and 25580 inner bearing -- industry-standard tapered roller bearings for this axle class.
LM67010 outer cup and 25520 inner cup are included so you can replace the full bearing assembly, not just the rollers.
Pre-selected grease seal and cotter pin eliminate separate sourcing trips and ensure correct fitment for this hub size.
Confirmed fit for 5,200 lb Lippert, Dexter, and Al-Ko axles -- the most widely deployed trailer axle platforms in the RV market.
This kit contains all components required to repack one axle hub. For a complete axle with two hubs (one per side), order two kits.
The LM67048/LM67010 outer bearing and 25580/25520 inner bearing pairing is the standard specification for hubs used on 5,200 lb capacity trailer axles. This covers a wide range of axle assemblies produced by Lippert, Dexter, and Al-Ko for travel trailers, fifth wheels, horse trailers, car haulers, and utility trailers with individual axle ratings at or near 5,200 lbs.
If you're unsure of your axle rating, check the axle tube or the trailer's compliance label (usually inside a cabinet or on the frame rail). The axle rating is typically stamped or labeled near the spindle end or on the axle manufacturer's tag.
Bearing service intervals depend on load, speed, and conditions, but general guidelines for RV and trailer use include:
This kit supplies the bearings, cups, seal, and cotter pin -- the following items are not included but are needed for a complete bearing service:
