Expert Reply:
For your 7,000 lb triple axle trailer, you will need to pull one of the hubs and get the inner and outer bearing numbers from it. Each of those bearings has a number printed on the face that will help determine what hubs you need. I am happy to assist with getting you the correct parts and will give you a complete list once we have the bearing numbers to confirm the proper fit.
If you cannot get the bearing numbers, then you can measure the spindle itself in the locations where the bearings sit and where the seal sits. This is a precise measurement so you need to use a digital caliper like # PTW80157. I've attached a video to assist as well as a photo showing the locations.

i will pull the hub today and get the numbers. i was worried about the distance between the backing plate mounting flange and the back of the idler hub that is currently on there. seems like the new hub with a drum on it wont reach the brake pads.
