putting in a new axle tomorrow, any advice for taking out the old one and puttin in the new one

 

Front or rear?

From what I understand the cam bolts for the front axle can get extremely seized in place and nearly need to be cut out.... may consider having some replacements.

If its the rear axle I would suggest getting new u-bolts.

Torches, sawzalls, and big hammers will be your friend
