Our take on the 3.5K Bearing Kit
This is a bearing replacement kit for 3,500 lb trailer axles. It contains one inner bearing and race (L68149/L68111), one outer bearing and race (L44649/L44610), a double-lip seal, a cotter pin and a tang washer. It suits one wheel hub, so a two-wheel axle needs two kits. It covers the common 3.5K spindle size, and the double-lip seal is the part that keeps water and grit out of the bearings.
- Matched bearing and race pairs for a 3.5K axle
- Double-lip seal better protects against water and dirt than a single-lip seal
- Includes cotter pin and tang washer, so no extra hardware run
- Standard Timken-style part numbers are easy to cross-reference
- Covers one hub only; a full axle needs two kits

Questions and answers
- Will this fit my 3,500 lb trailer axle?
- It is sized for 3.5K axles using the L68149/L68111 inner and L44649/L44610 outer bearings. Check the part numbers stamped on your old bearings or measure your spindle before ordering.
- Does one kit do both wheels?
- No. One kit covers a single hub, so a two-wheel axle needs two kits.
- Is the seal a double-lip type?
- Yes. The 10-172 seal has two lips, which helps keep water and grit out on boat and utility trailers.
- What is in the box?
- One inner bearing and race, one outer bearing and race, one double-lip seal, a cotter pin and a tang washer.
- Do I need to add grease?
- Yes. Bearings ship dry, so pack them with wheel bearing grease and add grease to the hub before assembly.
- Where is the 3.5K Bearing Kit cheapest?
- At Trailer Parts Kingdom, for $29.99, as of our latest check.
