Leaking axle seal 8 3/4

hello

No expert by any means here but I did just do this for the first time 3 weeks ago. Brewers has the seals and gaskets. They are not very expensive, check out their website. We pulled the chuck and replaced that gasket too. Used a 6 foot length of 1/2 inch pipe to knock the seals out from the opposite end and a pvc coupler, I think 2 1/2 inch, what ever the right size was to match up to the seal, as a driver, think those came to $4.50 at the hardware store. We packed the bearings as well as we could and adjusted the end play.
