Seal may look good but its def done, riding in the same spot for so many miles, new one will be tighter just be sure to be very careful sliding axle back in, dont just shove it in and slide along seal, support it the entire way, as in, don't stop half way and let it rest on the seal or even withe the spined ends, when you first put it through, very easy and slow. I take some new gear Oil and run it around edge of seal before insertion....
X2, for what its worth I would also change out the bearings aswell since you are already there.
