I got DW immediately after installing 2 inch ciol spring spacers on my 2005 Wrangler. I didnt leave anything loose and nothing was wornout. It took me a few days of pondering before I came to the realization that by lowering the front control arms, I actually decreased the CASTER angle. I went to the dealer to see about getting the adjustable eccentric cam bolts. The Dealer said they were $50 each. I was not going to pay that, so I improvised...
Purchase a piece of 1.5 inch flatbar steel (not aluminum or alloy) 3/16 inch thick. I bought a 3 foot long piece at OSH for $10.00. I cut 4 pieces off (all at 1.5 inch) to make 4 squares the same size. Take your time cutting them square (or close to it).
Jack up the front of your jeep and place the frame on stands. Dont have any preasure on the front axle, and remove one of your lower control arm bolts. See how much room there is in the slotted hole to move your axle forward as much as possible. This is how much off center you need to drill your holes in the 4 little square pieces you cut out.
You will need a 9/16 inch drill bit for the above holes. This is important because the bolt is right at 9/16 inch.
Make sure to set up a drill press jig so the drilled holes are all in the exact same place on all 4 squares. I made my drill press jig with scrap wood, screws and a clamp. Obviously you will need to set your jig up to drill the offset holes so as to move your axle as much forward at the bottom as the slot will allow.
Repeat the above instructions 4 times so you have 4 completed shims (all the same, dont reset your jig, use it for all the shims).
Install the offset washers on the lower control arm bolt/nut so as to add as much posative Caster as possible. Put one shim on each side of the lower control arm bolt/washer.
After you do this, you need to reset your front toe. I set mine so the front of my tire tread was 1/8 inch closer than the rear of the tire tread (done with a tape measure). Then you will need to re-center your steering wheel. Thats pretty simple, I just went for a test drive with the wrenches and every mile or so, I made an adjustment till the steering wheel was centered. If you are not esure how to set the toe or center the wheel, dont be afraid to ask.
Anyhow, If anyone has questions, dont be afraid to ask.
