As far as installing them, reverse the removal proceedure of the old ones. You will need to get the front end lined up when the new ones are installed. The adjusting nuts on the rods are how the caster of the wheels and tires are adjusted. With the new, uncrushed bushings, I'm sure the caster has been affected. The nuts also need to be torqued a specific amount also. A good alignment tech should know the specs.
