... If you compress the spring while it's on the truck and the truck is on the ground, the truck will just lean as you compress the spring and no slack will be created that will allow you to move the collar.
Step 1 for you is jack the truck up until the front suspension is fully drooped, then secure it there. At that point you *might* be able to use a small compressor set to compress the spring and adjust the collar.
Honestly, taking the coilovers off these trucks does not take that long, and for safety's sake I'd rather do it right.
