I have a 1969 C60 that I have been very slowly been working on and gathering parts for when I get time. I just replaced the 20" rims and tires today with new 22.5" Daytons and 295/75s. All was good and great after only breaking one stud until I got to the drivers side steer tire. The tire spun just a little and I figured I would work it back and forth to get it to break free with no luck. I ended up locking it in solid by hand and can't get it to move. I put the tire on and aligned it the best I could based off of rim/hub distance until I can figure out why it's not spinning.
It has air brakes obviously and this is my first truck with air brakes. I have only driven this truck about 5 miles in the past year or so. It's been driven maybe 1/4 mile in the last 2 weeks and didn't show any signs of a sticking tire. It has in my opinion always felt under powered for what I expect from a 427 so a sticking brake makes sense. What what be a good starting point for me to check on this hub to see why it isn't spinning? I just assume it has to be the brake sticking, I could be wrong and if I am I need help with a direction to go. Thanks for any help.
