@imiceman44 I didn't end up needing to try another method -
@Capt Ron came over and we got a couple jacks beneath the front axle. I pushed, he pulled, and it rolled pretty easy. It was definitely in gear this morning which explains the truck not moving at all... oops!
A major thanks to Ron for coming over. We had it moved in just about 2-3 minutes. He hung out for a little while after and taught me a bunch of things about the truck. Thanks again, man!!
With the truck in its new position, the driver's side axle shaft came out easy!
After Ron headed out, I went after the remaining three kingpin caps. Passenger-side lower, driver-side upper and lower. None of them would budge!
Oddly enough, the upper cap looks thicker on the driver's side than it did on the passenger side. Here is a photo of it:
There were cap screws holding the upper kingpin cap down on the passenger side, but on the driver's side it is studs. One of them unfortunately came out as you can see in the previous photo.
The bottom cap on the driver's side is stuck just like the passenger side. But I took a cold chisel to it and managed to get it to turn a little at least.
After about 30ish minutes I decided to just spray everything with penetrating fluid and try again tomorrow!
