Expert Reply:

Based off of the info given, your 4,000 lb axles should use the same bearings and seals as a 3,500 lb axle so here are the parts you'll be needing:

- Hub Bearing Kit for Lippert, Dexter, and AL-KO Axles - 3,500 lb with #84 Spindle # BK2-100
- Bearing Buddy Chrome # BB1980A or Stainless Steel # BB1980A-SS

These Bearing Buddy caps fit a hub bore that have a 1.98" which is pretty standard for a 3,500 lb axle hub. If you measure something different please let me know and I'll be happy to help you find the correct parts!

Keep in mind that any oil currently inside the hub, on your bearings, and on the spindle will need to be completely cleaned off otherwise the grease and oil can interact with each other and cause the grease to be less effective.
