Brandon, I used a impact when i did mine and it worked, it was slow due to all the loc-tite on the bolts but they came out eventually.
Have a good grinder with a zip cut disk(or 3) on it for cuting the bumper supports, and pay attention to where to make the cuts, it took me a while to get mine right. Front is harder than rear.
Watch that back bolt on the fender side of the front bumper cover, they tend to snap off and are in a totally enclosed area, you,ll know it when you see it, if you can get at it and put some penetrating oil on it before hand it should help(wish I would have)
The project on here gives some good hints.I did it by myself, but extra hands sure will help
MAKE SURE your A.C. hose is clear of the bottom of the harmonic balancer before firing up the truck!!!!!!(sorry for yelling
)
I have some pic.s of the process in the link
Good luck, its not that bad, Todd
