I've replaced the driver side rear axle seal twice and it is still leaking. I'm using a seal driver, but it gets slightly cock-eyed toward the top every time. It happened on the passenger side as well, but I hammered a little harder and got it set in...and no leaks yet on that side. The driver side is being a pain in the ass and now I'm going to have to order another seal. I'm going to be like $60 down in seals and shipping at this point.
