There's a some Youtube videos on "no spring compressor install", I watched 1 or 2 and read about it a bit. In short:
- Get the front end on jackstands, the forward skid plate removed, swaybar endlinks removed from spindle (which you have to do anyway; 14mm nut and 6mm allen wrench), and remove the 2 19mm bolts that hold the spindle to the lower control arm (near the lower ball joint), support the hub at the wheel studs with a 2x4 or whatever you have.
- Remove the 3 14mm nuts on the coil top hat; remove the 17mm (or 19mm) nut on the shock stem. Remove the lower shock mount bolt.
- Pull the existing coil/strut, knock the old top hat out. Lever down the lower control arm for more clearance, if needed.
- Make several match marks on all of the alignment adjustment tabs (make sure to get all of them). I made 3 match marks per tab, one w/ silver Sharpie and 2 with black Sharpie.
- Loosen the 19mm alignment cam bolts. You'll know when they're loose enough - the lower control arm will literally swing down to a vertical position.
- Install your new top hat + rubber isolator into the vehicle shock mount w/ the 14mm nuts.
- Grab your new strut and coil, work the strut top post through the hole in the top hat. Make sure you have the lower washer installed before doing this! Spin the top nut on, do not tighten - you just want to hold it in place.
- Guide the lower strut mount into position as you lever up the lower control arm. As soon as it's in the cradle, run the bolt through and hand-tighten the nut.
- Use your factory bottle jack under the lower control arm, crank it up!
- Remove the nut from the top of the strut, install the supplied bushing and washer, install the nut and tighten until the bushings begin to expand.
- Reinstall the 2 19mm bolts for the lower control arm to spindle. Torque to 160 ft lbs, use threadlocker.
- Reinstall swaybar endlinks, put your tires on, lower truck. At this point, I used a floor jack and lifted the front end to the limit of my jack, and dropped it - 3 times, to let things settle.
- Torque your lower strut nut + bolt to 100 ft lbs.
- Check your alignment tabs. 3 of mine barely moved, one moved about 1/4 of a revolution. I think I used a 1 1/16" socket to get the alignment cams back to the match marks. Then, torque these to 100 ft lbs.
I think that's it. Notice I didn't need to touch the lower ball joint or tie rod ends; and not using a spring compressor took the anxiety down several notches. After doing 1 side, the other side took maybe 30-45 minutes? (and that included removing my XREAS hydraulic stuff too).
