The best way to identify the correct replacement components for your trailer is by using the part numbers from your current inner and outer bearings and grease seals (or a spindle measurement where the seal and bearings ride). It is possible to measure the spindles to obtain grease seal dimensions (location B on the photo) but this process requires care and a precision digital caliper like # PTW80157. You will also need to confirm the diameter of your wheel studs. We already know your brakes are 12 x 2 and that your axles are 6000-lb rated. Please refer to the photo provided which shows where to find the part numbers and where to measure your spindles to obtain the grease seal inner diameter.

I have provided a link to our product page for integrated 12 x 2-inch hub/drum assemblies, with the 6 on 5-1/2 bolt pattern, suited for 6000-lb axles. The part you referenced, Dexter EZ-Lube Trailer Hub and Drum Assembly, part # 8-201-5UC3-EZ, uses this 6 on 5-1/2 wheel bolt pattern. This part is intended for 5200-lb axles and includes the hub/drum, bearings (inner bearing 25580 and outer bearing LM67048) , races, seal, grease cap, wheel bolts and lug nuts.

If your 6000-lb trailer axle uses inner bearing 25580 and outer bearing 15123, and EZ-Lube spindles, you can use part # 8-201-9UC3-EZ. This part also includes the hub/drum, bearings, races, seal, grease cap, wheel bolts and lug nuts and comes pre-greased. I have linked a product review video for this part.

If your brakes use a 5-bolt mount (which is most likely) you can use part # AKEBRK-7R-SA for the right-hand side and part # AKEBRK-7L-SA for the left. These are self adjusting brakes that do not require manual adjustment.

We recommend that you use new hardware to install the brakes. You will need either 4- or 5-per wheel of each of the following: nuts, part # 38N; lock washer, part # 38LW; and bolts, part # 7-5.

I have also included an article concerning packing trailer bearings. We offer a bearing packer to simplify the process, part # L70025, and we also offer bearing grease, such as part # L11390. An article regarding identification of wheel bolt patterns is also provided.

Answer 1

The maximum hub bore measurement for the 5,200 LB or 6,000 LB Dexter hub and drum assembly #8-201-5UC3-EZ is 3.622 inches. So a wheel with center bore of 3-3/4 inches would fit.

Answer 2

With bearings #25580 and #LM67048 the correct hub and drum assemblies are #8-201-5UC3-EZ if you have EZ lube spindles or #8-201-5UC3 for standard spindles. The only issue is the measurement of your seal. These hub assemblies use a seal with a 2.125…

Yes, for a hub with a 6 on 5-1/2 inch bolt pattern that has the same bearings as the part #BK3-300 we have the hub part #8-201-5UC3-EZ from Dexter.

We do carry Dexter hubs for the 5,200 lb Lippert Axle that have an outer bearing of #LM67048 and an inner bearing of #25580 like part #8-201-5UC3-EZ. You would just want to measure the grease seal inner and outer diameter to make sure the grease…

We have hubs that will fit your spindle, but they all have 6 on 5-1/2 inch bolt patterns like the part #8-201-5UC3-EZ. You actually got incredibly lucky though as 99% of the time mobile home axles don't use standard trailer parts so none of the…

The difference between an load range C and load range D tire in the same size is the capacity and psi rating. The two tires will still have the same dimensions and fit on the same wheel. The D rated tire has a higher capacity. For a ST175/80D13 like…

Answer 12

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…
