I have a 2013 Northwoods Arctic fox 29-5K 5th wheel with Al-Ko 406068 axles on it. Can you tell me which bearing kit I need? Thank You!

Expert Reply:

Since AL-KO is no longer around, you will need to check your existing bearings to find the correct replacement. If you remove your hub you can look for the bearing numbers stamped in the face of each bearing. If these are worn or missing you can measure the inner diameter of your bearings using a digital caliper like # PTW80157. See the diagram below.

If you find that you have a # 14125A outer and # 25580 inner bearing with a grease seal that has a 2.125" inner diameter you will be able to use the # BK3-210 you were looking at. If your grease seal has a 2.250" ID you would need the # BK3-200 instead.
