Question:

I am getting ready to pack the bearings on 2024 outdoors rv 260 kvs. the axles are 5200 lbs. I am not sure of spindle size. Looking at the sticker on the axles. B21-5651, PO: 227025, D52 capacity 5200 lbs, HF=86.6 SC=68.25. Hopefully this is enough information. It is outside and and I do not want to put it on jacks until I have the parts. I would like to get new inner seals and Carter pins if these axles have pins. Thanks

Expert Reply:

Hey Philip! Can you get the serial number off of that axle tag? We have two different bearing kits that will work with the difference being the grease seal. If your existing grease seal has a 2.25" inner diameter (ID) you can use the # BK3-300 and if it is a 2.125" ID # BK3-310. Dexter won't be able to tell us which one you actually have without the serial number.
