    No... You've gotta remove the case from the truck. It takes about 20-30 minutes on a lift.

    Does removing the case require any special tools that the average person would not have?

    If you have the skills and tools to disassemble the case, removal should be easy.

    That's correct.

    You should also replace the bolts which hold the case halves together with the newest shielded bolts to prevent corrosion between the bolts and the case. The cases are magnesium, and corrosion of the case from the dissimilar metal of the bolts is a huge issue with those units.

    The bolts that are holding the two halves together are shielded bolts. Do I still need to replace them with new ones?

    Not necessarily. If you already have the shielded bolts, and the shields are in good shape, you'll be fine to re-use them. The earlier design bolts had a coating instead of the shield. Once the bolts were tightened in place and then removed once, the coating was gone, leaving the bolt directly against the case... not good.
