Before the bed goes back on I need to paint the rear frame and suspension. Just like the front, I took a wire wheel to everything behind the cab. It was tough, but effective. Then I used a pressure washer for the nooks and crannies (and sprayed off the cab as well).

Ready for some POR-15:
Some questions:
1) Would it be worth changing the diff oil at this point?
2) Worried some water got in the wheel cylinders so I sprayed some brake cleaner in there to dry it out? See any problem with that?
3) Plan to paint the frame, trailing arms, axle and underside of bed with POR-15, any places it SHOULDN'T be applied? I'm aware of its UV sensitivity.
