Well, I finally got around to fixing the flashing 4x4 lights; I checked the resistance and one solenoid was normal (45 Ohms) and one was way off, at 160 Ohms.

Got that fixed and the next day I had my check engine light come on for O2 sensor and a stored P0420 (Catalytic Converter) codes. I replaced the O2 sensor (we will see if the Cat conv code comes back) and while I was under there I noticed the transmission bushings (pretty sure thats what they are) are really worn (one is almost completely worn away on the outside, the other looks like it is ok but still worn.)

Any one had this problem? Any advice on where to get the parts?

TLDR: replaced O2 sensor and freewheel solenoid, discovered broken transmission bushings and need advice on replacing them
