I'm in the process of replacing the rear diff lock actuator on my 98. I took the original out in the unlocked position, and my understanding from other threads is that I can manually lock it using a screwdriver/prybar once it's out in order to correctly install the replacement in the locked position. So far I have the truck wheels off the ground in neutral, and spinning the driveshaft while prying the cylinder with the bolt hole to the right. I can't get it to budge, and I'm worried that I'm going to break something if I pry any harder. Just wanting to make sure I'm doing this right, no I don't have the FSM unfortunately.
