What Hub/Drum Bearings, and Grease Seals do I Need for My 3k Axle with 5 on 4-1/2 Bolt Pattern?

Question

Question:

Good evening, Hoping you can help me find the correct hub for an enclosed Diamond Cargo single axle trailer. The sticker on the trailer reads: REAR 1356 KG 2990 LB. Ive measured the lug pattern to be 4.5 with 5 lugs. One of the studs stripped in the hub, so I would just like to replace the entire assembly.. hub, bearings, the works. Thank you in advance.

Since your sticker reads 2990 pounds, you have either a 3k or 3.5k axle. In order to identify what axle you have, I always recommend checking the bearing numbers from the hubs you have. In order to do so, you simply need to remove the inner and outer bearings from the hub and wipe off the grease. Once the grease is wiped, it will reveal the part numbers along the outer rim. I went ahead and attached a diagram to help you identify where the bearings sit on the axle spindles.

If you have an inner bearing number of LM67048 and an outer bearing number of L44649, you have a 3k axle. If you have an inner bearing number of L68149 and an outer bearing number of L44649, you have a 3.5k axle. Note that the outer bearings will be the same, so you also need to look at the inner bearing to confirm what you have.

For a 3k axle with 5 on 4-1/2 lug pattern, the correct replacement hub you need is the Dexter Trailer Hub and Drum 008-418-02. For each of the hubs, you need 1 Replacement Trailer Hub Bearing - LM67048 # LM67048 and 1 Replacement Trailer Hub Bearing - L44649 # L44649. In order to make sure these are the correct hub and parts you need, I recommend matching your inner bearing and outer bearing numbers to make sure they are LM67048 and L44649. We currently do not have a idler hub (non-braked hub) with the capacity and lug pattern that matches your trailer.

As far as the additional parts you need, you also need the Grease Seal - Double Lip - ID 1.719" / OD 2.565" - for 3,500-lb Axles # 58846.

For a 3.5k axle with a 5 on 4-1/2 lug pattern, we carry the following options:

- Easy Grease Trailer Hub and Drum Assembly # AKHD-545-35-EZ-K (if you have EZ Lube spindles)
- Dexter Hub/Drum # 84546UC3 (if you have standard spindles)
- Dexter Trailer Idler Hub Assembly # 84545UC1-EZ (for non-braking axles with EZ Lube spindles)
- Dexter Trailer Idler Hub Assembly # 84545BX (for non-braking axles with standard spindles)

All of these parts for a 3.5k axle come with bearings, grease seals, and races.

Answer 3

The 7290 that you see is a casting number. It is found on AL-KO hubs that fit #99 spindles. I found that the bearings used are #28580 which would be the inner bearing and #25580 which would be the outer bearing. For the seal use #91030.

The two sizes you mentioned are pretty similar and fit many of the same 15 inch wheels. The 205/75-15 fits rim widths of 5 inch to 6-1/2 inch whereas the 225/75-15 fits widths that are 5 inch to 6 inch. The 205 is 27.1 inches tall and the 225 is 28.4…

A TruRyde rvd-h-865 7k hub/drum like # AKHD-865-7-2-K uses 1/2-inch drive-in studs that are 1-5/16-inches long. For a replacement stud you can use #165981. This is slightly longer at 1-1/2-inches but it has the same 1/2-inch diameter. They are also…

To make a 7-way to 6-way square adapter will require you to get the part #37995 to use the 6-way end and then wire up a 7-way to it like part #H20043. This will give you the adapter you would need since there isn't one already pre-made.
