Question:

Im am trying put my trailer hub back together. The inner bearing I bought is too big. The hub number is AL-KO 7290. I need a bearing that will run on a race that tapers from 3 1/4inch to 2 31/32over 15/16. ID of the bearing is 2. Also, I need a new seal. The dimensions of the seal is 2 3/4inch iD and 3 25/32inch OD. And 3/4inch thick. Do you have what I need or can you provide the part numbers or direct me to a source?

Helpful Expert Reply:

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.

Michael, do you stock a 7290 in a 4.75 pilot? Needing one complete with hub cap, bearings and brake assembly.

@ToddG Hey Todd, I have been working on getting the right hub added for you, but running into some hiccups along the way. The Hub you have is an old AL-KO hub that is no longer made. Can you please respond directly to the email that you receive with a picture of your axle tag? That way I can forward it to Dexter to see what will work.
