Question:

Hello, I have a 2020 Eclipse Attitude 21 SAG LE with 2 Lippert Axles B21-500. EZ Lube Axles. I plan on measuring the ID of the seal to validate I have the 2.25inch seal and that these hubs would work. After inspection of the hubs, if they are in good shape I will just rebuild with bearing kit BK3-300. 1. Can you tell me the standalone part number for the nut/washer that comes in the kit along with the dust cap/rubber plug part number? 2. Second question is it looks like the only difference between 8-201-5UC3-EZ and K08-201-98 the seal is 2.125inch ID compared to 2.25. Why is the pricing so different between the two. $94 more seems pretty steep for the difference of a seal. Seems like I should purchase the 8-201-5UC3-EZ and swap out the seal that comes with the hub 10-10 2.125inch ID/3.376inch OD with the 10-36 2.25ID/3.376inch OD RG06-070 and save $94/hub minus the cost of the seals. Can you confirm if this is an option that would work to save just under $400 for my trailer 4 hubs?

Hey Joel.

To answer your first question, # 6-191 is the nut, # 6-190 is the nut retainer/washer, # 21-42-1 is the dust cap, and # RG04-010 is the rubber plug you're looking for. Your second questions assumption is correct, the only difference between the two is the seal and the pricing could be a whole list of things. If the # 10-36 is the seal you need, then purchasing # 8-201-5UC3-EZ and switching out the seals would work just fine.

Were you able to take the Eclipse out on any trips this year?
