Mike, I just finished doing this on my 59 1/2 ton. Assuming that it has
not been damaged some how the trick is keeping the seal VERY straight
when putting it in. Since I had everything out of the axle I housing I
stood it on end and then drove it in using a seal driver and a mallet.
As someone already mentioned you could use a plastic pipe with the same
O.D. as the seal instead of the seal driver.. Again, as you drive it
in make sure it stays straight.
