Grease seals for 7k Dexter axles on 2018 377?

Anyone have the part number? With all the ezlube horror stories Iíve read here, I think Iíll manually pack the bearings. Even though Iíve never had issues with the ezlubes on my boat trailer, pumping them every season...

The numbers you need are on the axel. Or you can call Camping World and ask parts.

Look on the axle tag and confirm the capacity, then you can use the Parts Replacements tables from the Dexter Axle manual online to find the Dexter P/N for the seals:

Dexter Axle Parts Replacement Tables

I start with the Bearing Replacement table - find your axle capacity in the right hand column and the Brake/Hub size in the first 2 columns. For 7K I see either a 5 bolt demount or 8 bolt, but both are 12" x 2" brake size. Now go to the Seal Replacement table and find your brake size and hub size. In this case both the 5 bolt and 8 bolt use the same seal - Dexter P/N K71-305-00. Make sure that you get a double-lip seal for use with the E-Z Lube system.

Thanks, that was the reference guide I couldnít find on the Dexter site. Appreciate the help.

For whatís itís worth, these were my seals:

Did the whole job in about 2.5 hrs, including greasing the suspension points. Now I have a baseline of mileage to brake wear, by fulling pulling wheels and drums, so I might just use the EZlube function next time. The torque sequence on the wheels gets old with 32 lugs...
