On my 52 6400, I had to replace the axle seal. My question is this. My rearend plug is boogered up from the previous owners. It's almost impossible to get any kind of wrench to work at all. On the front of the rear and on top of the output shaft, there is another plug. Can that also be used as a fill point. Is that 2 speed rear open all the way back to the rear cover. If so, then I will be able to get grease all the way out to my bearings in the hub. Hope thats clear enough.
