Yes this is possible at least for a crew cab short bed. As NHUSA mentioned if you can get the right rear wheel off of the ground then you can get it out. I did this alone and without removing the spare and it wasnt too bad. A helper and removal of the spare would have saved me a good bit of time and effort of going back to front to make adjustments.

The truck was repaired today, vacuum pump booster and the belt were replaced.

I had the same thing happen over the weekend. While sitting in stop and go traffic and easing forward the pedal became hard to push and there was little power assist. Once I got moving it didnt return until I was pulling into a parking space later and the same thing happened so I have narrowed it down to low speeds and it does it more frequently in reverse. I suspect it to be the vacuum pump as others have mentioned here but i will find out as its at the dealer for service tomorrow. For what its worth mine is a 2014 CCSB 5.3 4x4 with 80k.
