8-3/4 axle seals?

The inner seal is pressed into the axle housing. The outer seals are in the axle retainer plate and cannot be removed unless the bearing is removed from the axle.
If the bearings are not having any issues I would not change them. You should grease them while they are out. I used a needle adapter for the grease gun.
Got the axle pulled, looks like the gear lube pushed out the grease from the bearings. I'm still not too worried about them since they had gear lube for what little time I ran it.
Of course oriellys gave me the wrong seals, so I get to make a trip back into town. Also, when I got the drum off I noticed the axle can move in and out more than I would think I acceptable, (1/8-1/4) is there a way to tighten this up?
Thanks!
