Replacement Bearing Kit for 7k Axle


I need replacement bearings races and seals for for a 1999 take 3 trailer with 7k axles what is the correct part number?


Expert Reply:

In order to choose the correct replacement bearing kit of your 7,000 lb axle, you will need to know both the inner and outer bearing numbers, as well as the inner diameter of the grease seal, which you can find using a digital caliper.

The most common bearings on 7k axles are inner bearing # 25580 and outer bearing # 14125A. If those are your bearing numbers and the inner diameter of your grease seal measures 2.125 inches, you would want bearing kit # BK3-210, which includes the bearings, races and seal.

Should your seal measure have an inner diameter of 2.25 inches, the bearing kit you want would be # BK3-200.

I have added links to video reviews of each kit for you to take a look at.
