I took the starter out. The contacts looked good. It may have a dead spot. I'm going to have it tested. For some reason the fan was removed when I got the truck. I'm wondering if they were trying to turn the starter off a dead spot by turning the bolt on the end of the crank. They have this bubba installed battery cutoff switch in the cab too. Probably had a battery drain at some point but I didn't notice one when I hooked up the battery.

What lubricant do you recommend?

Thanks
