Recommended Hub Components For Dexter 4,300-Lb Axle On 2013 Airstream Trailer  

Updated 03/30/2016 | Published 03/27/2016

Question:

I have a 2013 Airstream single axle trailer with a Dexter Axle Model 4300# and serial Number 121765142. I plan on servicing the bearings when I get it out of storage but dont know what size seals I need. I do not have access to the trailer at this time. Do you have a reference to check and see what size/part numbers I need? Thanks much,

I found the components you need for your Dexter axle on your Airstream trailer.

The grease seal you need is part # RG06-070. The inner bearing is part # 25580. The inner race is part # 25520.

The outer bearing is part # LM67048, and the outer race is part # LM67010. I have also attached a helpful article that explains how to replace hub components.

To make the job of packing the wheel bearing much easier I recommend a bearing packer like part # L70025. For grease I recommend part # L11465. And if you do not have a grease gun I recommend part # L30200
