Ok, here is what I did.
Passenger side: pulled the nut off, used the cab lift cylinder to lif the cab front and swap was easy. I left the bolt snug but not tight. Moved to Driver side.
Driver side:
I pulled the grill off. removed the nut from underneath using an extension and breaker bar. I left the bumper on. Applied a little pressure from the cab cylinder. Then put a small jack in.
I went as far to the drivers side as it would fit as the pivot tube bowed when In the center.
Swapped top bushing. Put the bolt back in. Lowered red jack and cab making sure rubber lip is inside hole. (I had to use a ratchet strap to pull the back of the cab over and used pry bars to push everything into alignment.
once all the way down, I cussed for about an hour trying to get the lower bushing, washer, and nut in place. Then tighten both sides.
Anyone know the torque for these?
