It sounds like you're trying to replace hubs on a mobile home axle. Mobile home axles are designed for one time use, to transport the mobile home from point A to point B and then intended to be discarded after that. Because of this, replacement parts are rarely available for most mobile home axles and although we don't have a hub that matches the bearing sizes you mentioned, we have replacement bearings that may work to service your existing hub.

For a bearing with a 1.375 inch inner diameter, we have # LM48548, which uses race # LM48510 with a 2.563 inch outer diameter and is sold separately.

We have four bearing options that have a 1.25 inch inner diameter. I'll list them below along with their matching races available separately.

# 02475 which uses race # 02420 (2.688 OD)
# 14125A which uses race # 14276 (2.717 OD)
# 15123 which uses race # 15245 (2.441 OD)
# LM67048 which uses race # LM67010 (2.328 OD)

The closest grease seals we have are part # BB60002, with a 2.562 inch OD and 1.875 inch ID. The 0.025 inch discrepancy should not make much of a difference but this will depend on how accurately you measured the portion of the spindle on which the seal rides. I recommend using a digital caliper like # PTW80157 to confirm the accuracy of all your measurements.

I may have an option for you but mobile home axles are considered a one-time use only product and are not designed to be used on a standard trailer. Therefore, there are no hub conversion kits for them that will allow you to use standard…

The 8-14.5 tires will be 1" wider than your current 7-14.5 tires so you'll be losing 1/2" of sidewall clearance to your fender. I recommend having at least 1" of clearance to the sidewall so it would be best to stick with 7-14.5…

Thanks for the picture! If you can't get your races out, you'll just need the entire new hub assembly #AKIHUB-545-2-EZ-2K which comes with brand new races already installed, new bearings, and new grease seals but you'll need to use #34823…

For your Dico Hub 45263, you are going to want to use part #L44649 for both the inner/outer bearings and part #168255TB for the grease seal which has a double lip. I was not able to confirm that the hub uses different inner and outer bearings.…

Answer 8

We've had customers with your Dico 45263 hub in the past get us their bearing numbers so we know that for a replacement with the wheel bolt pattern you need you could use the #AKIHUB-545-2-G-EZ-2K and you'd be set.

Hey James, you can go with a 4k axle leaf spring like the part #e22YR in place of what you have now while it has a slightly higher weight capacity it's not enough that it would create a harsh ride quality. This is a 26 inch long spring though so…
