Replacement 8-259 Hub With 2,000 lb Capacity and 5 on 4-1/2 Bolt Pattern

Question:

We finally got a break from snow and rain - the back of the Dexter hub is marked 8-259 in one location and has 156 marked in another location. The bearing races themselves didn't have any laser or stamped markings and the inner races were nearly completely destroyed. Please advise which models that you stock are considered suitable replacements for the failed hub or advise if you need more info.

In order to find the correct hub for your trailer you will need to take the current hub off, take it apart and find the bearing numbers, which will be stamped on the bearings themselves. If you get back to me with that information I may be able to help you find the right hub.

Thank you for the information. There are two possibilities, but because your bearings did not have any markings you need to use a digital caliper such as # 301-17068 to measure your spindle where the bearings and grease seal ride (see accompanying photo) to find the correct option. Hub Assembly # 8-259-5UC1 uses inner and outer bearing # L44649, which have an inner diameter of 1.063", and grease seal # 10-9, which has an inner diameter of 1.5". Hub Assembly # 34822545BX uses inner and outer bearing # L44643, which have an inner diameter of 1.0" and grease seal # 34823, which has an inner diameter of 1.249". The measurements from your spindle will match up with the above measurements and that will let you know which hub assembly to get. I've added links to video reviews of these parts for you to take a look at as well.
