Trailer wheel-bearing kits are identified by the markings on both bearings and races, plus the grease-seal dimensions. These three Lippert kits serve different wheel-end specifications: one uses matching inner and outer bearings, while the 3,500 lb and 6,000 lb kits use two different bearing sizes.

Before ordering
Use the bearing and cup numbers stamped on the parts removed from the hub, plus the original seal inner and outer dimensions. An axle's stated capacity does not establish the bearings in every hub version. All three products are one-wheel-end service kits, not bearing sets for both wheels on an axle. When a trailer uses a different spindle-washer arrangement, follow the axle manufacturer's instruction rather than substituting the supplied tang washer.
