Hi, in step 19, you mentioned "you can now go to the pass side, and take out the 2 shock mount bolts. Tilt the hub assembly out, and use a pry bar to pop axle out of upper oil pan. You do not need to remove this, just pop it out of the diff". Can you please explain why you need to remove axle on the pass side? Also, can I replace engine mounts (pass and driver sides) at this time? Thanks in advance.
