went out late last night to get my son some medication, and i parked the truck close to the house last time i parked it, well this time it was stop against the house ... lol ??? what would cause the truck to slowly crawl forward even in park, Compression? Torq Conve??

Torque converter. I didnt realize the truck was an auto, good chance that's your vibration. If you command lockup with the scan tool at speed and the vibration changes that's going to be the problem.

This may sound lame but loosen your belts and then check your waterpump, you said there was some play in your fan clutch, well, were the belts loose when you checked? Tire balance you will feel in your steering wheel, carrier berring and or u joint you will feel in your seat.
