But is this a Ford Chassis? Everything on Chevy is better and easier, you know.
There "should be" a manual crank position for your slides, but I do not know from experience if or where.
But SHOCKS, Oh Yeah:
I just changed our fronts, on Ford, with ordinary combination (box/open end) wrenches. On our older Ford (signature) the upper nut (hidden behind the fender liner) was 17MM and there was a 19MM hex on the shock shaft below. Nut holding the bottom end of the shock to the Radius Arm was also 18MM. I think by your year the fasteners on the Ford OEM shocks were bigger. Around 21MM or 13/16". I had a set of new Ford OEM shocks from a 2012 that had been converted to 4x4 so I installed them along with Axles, Brakes, Radius Arms etc. to upgrade the axle from 4600-lb to 5000-lb and get all new ball joints and bushings.
OK back to shocks. Here's what I did. In my case the springs came out before I worked on the upper shock mounts. That made it VERY easy to retain the upper nut with a box end that I wiggled into place and turn the hex on the shock from below. I could get maybe 1/3 of a turn on the hex. With the spring in place, maybe 1/8 of a turn and that's a problem because one flat of the nut calls for 1/6. If I had to do a front shock job, even without replacing springs, I think I would drop the springs out of their upper pockets.
So my process would be: Lift Coach and put Jack Stands under Frame. Remove Wheels. Disconnect one end of Sway Bar at Axle Link. If you don't disconnect the Sway Bar it won't let one side drop without the other. Remove Nut from Lower Mount at Radius Arm. Place floor jack under lower ball joint. Mark Spring with Tape matching the little Retaining Clip and remove Clip (10MM). Lower Floor Jack till Spring tips out at Top. Push Shock of Lower Mount. I don't think this will let Axle drop enough to strain the Brake Hose or ABS Cable but watch carefully. R&R the Shock. Reverse to assemble. The Retaining Clip notches into the upper Spring Pocket but that's easy. Getting the bottom of the shock onto the pin mount in the radius arm takes twist and push but do-able.
What I don't know is if Bilstein furnishes a different mounting bushing/nut/washer set than OEM. I believe they might.
