I use a slide hammer with a hook bit on the end of it. Pops the seal right out. If not, you should be able to carefully pry it out with a screwdriver and a hammer. Just make sure you only do damage to the seal and not the axle tube!
To install, just use a soft mallet and a brass punch. Or, if you can get your hands on a socket or piece of pipe that is as big as the seal, you can use that to ease it in. Take your time so you dont get it started crooked.
yeah! i found a small pry bar, got it behind the seal and pry'd it right out.. now getting the new seal in place, i also found a PVC tubbing but when i hit it, the seal keeps going at an angle on me.. i guess i'll have to keep trying tomorrow.. i'm done for the night Thanks!
