Replacing Bearings, Races, Seals and Dust Caps on a 5th Wheel Trailer
Products Featured in This Question
Question:
Greetings, I plan to replace the bearings, race, seals and dust caps on my 5th wheel before spring. The axles are Dexter part number 4003321. Can you determine the spindle size and required parts without me taking the hubs apart? Thanks
asked by: Robert R
Expert Reply:
Yes, the Dexter axle part number 4003321 you referenced works with the hub and drum assembly part # 8-201-5UC3-EZ which is a 5,200 pound axle. The hub pattern is 6 on 5-1/2.
The parts you will need are inner bearing # 25580 (4) and outer bearing # LM67048 (4). You will need seals # RG06-090 and dust cap # RG04-080. The seal and dust cap will come as a pair.
I have included a FAQ and multiple videos for you too.
