I just replaced mine not long ago along with the steering pump. Like Matt said, its not hard just time consuming. My friend Jay and I did it in a little over three hours with air tools. I unbolted the lower control arms, popped the cv axles out of the diff, then pulled out the front diff. From there you have access to everything. An alignment is needed after replacing the rack since it comes with all new inner and out tie rods so that's why I decided to take the lower control arms off from the frame. I kept it connected to the steering knuckle by the lower ball joint. To make this easier I took out the strut fork bolts
