Expert Reply:

The most common bearings and seals for a 7,000 pound axle are # 25580 inner bearing, # 14125A outer bearing, # 25520 inner race and # 14276 outer race. The grease seal can vary, and will usually either be the # GS-2250DL, which has a 2.250 inch inner diameter and 3.376 outer diameter, or # GS2125DL with a 2.125 inch inner diameter and 3.376 inch outer diameter.

We do also offer complete bearing kits for this axle. For the GS-2250DL grease seal, you can use the Kit # BK3-200. For the # GS-2125DL grease seal, you will use Kit # BK3-210. These kits include the bearings, races, grease seal and cotter pin.

I recommend pulling your hub and verifying these numbers as there is still a possibility that yours may be different. The bearing numbers should be stamped onto the bearings themselves, or you can measure the spindle at various locations if these cannot be found. I have attached an image that shows these measurements.

I have also included an article on trailer wheel bearings that you may find helpful.
