Leveling coil installation isn't extremely difficult, as long as you have access to the proper tools and equipment. Tools I used: 1/2" Air Impact Wrench, 1/2" Rachet & Breaker Bar, 1/2" Metric & Standard Sockets, 18mm & 1_1/8" Wrenches, 8" & 12" Adj. Wrenches, Coil Spring Compressor, 2 2-Ton Floor Jacks, 2 3-Ton Jack Stands, & 1 Can of PB Blaster.
First off, I jacked up the truck by the axles, and placed both jackstands to hold the frame rails by the radius arm crossmember. Next, I lowered the jacks to float out the suspension, and removed the bolt holding the swaybar to the axle, and also unfastened the shocks from their upper mounting spots, which allowed for full drop of the axles. Next, I removed the nut that holds the coil to its perches, using the 1 1/8" wrench & a good bit of PB Blaster (this step make take awhile) Next, I used the spring compressor to remove the stock coil (this may or may not be necessary, depending on how much drop of the axles is present). At this point I decided to take some time to clean up and repaint the parts that hold the coils in, to help keep rusting to a minimum. After the paint had dried, I continued with installing the leveling coil. I placed the coil over the stud, then moved the coil into its seat, while keeping pressure on the 4x4 hub (this allowed for installation without the spring compressor). Once the coil was in its seat, i placed the jack under the axle and lifted the axle till it was setting about level. Then I put the beveled washer, and nut back on the stud, and tightened it down, reconnected the swaybar, and upper mount of the shock. (if reusing the stock shocks, use an shock extension stud, available at most auto parts stores, to prevent shock damage). Repeat same procedure for other side. Pictures of the truck were taken after installation.
