hub assembly

i replaced one on my '00 GT vert a couple months ago and yes, it's as easy as it looks.
knock the old one off and pop the new one on. be sure, of course, not to dent the seal when installing the new one, since it does take some force to get the new one on. if you don't feel comfortable with the amount of pressure you're applying, i would recommend heating up the new assembly in the oven. this will loosen it up just enough to push it on.
good luck...although you shouldn't need it.

I made a thread on "hub bearing" installation with pics and everything in 4.6 tech. Do a search for it...
