Replaced my LCA's with new factory LCA's. My cams were frozen so the alignment shop didn't have much to work with. With 134k on the odometer I figured it wouldn't hurt to replace the balljoints.
The two rear cams came out pretty easy, but the two fronts I had to cut out with a Sawzall. What a pain in the butt that was. The whole project took me about 8hrs, but that included a run to HomeDepot for cutting blades and waiting for the paint to dry after I touched up the scratches from the saw blade on the frame with chassis paint. I also painted the LBJ brackets that bolt to the bottom of the knuckles since I had them off.
My advice to anyone doing this is to have all cams/bolts in hand prior to starting and assume you will have to cut them out......if not, consider yourself very lucky and just return the parts that you don't use.
I found this guide to be very helpful

My next big project will be rotors, pads, and calipers all the way around.
