I did it myself in about an hour. It wasnt hard for me, but I have a general knowledge of automotive repair and the tools required. I also had a donor vlave body so that saved time. The pita part is reinstalling the valve body and keeping the spring and accumulators to stay put while lifting the valve body up and bolting it back in while on your back.

Use mechanics wire through the springs and secured to 2 pan bolts to help. It can be tricky for the average joe but, you can do it.

We dont need to use the washer on the od/ud accumulators fyi. You will understand when you read the directions.
