Thanks for the socket sizes. It took about 20 minutes with air tools to install. I have to say that the truck has never steered this straight! I dont have to over correct it anymore! I think I still have a little play in the wheel. That I will have to fool around with those screw ajustment on the steering box. Any thoughts? But the DSS kit is well worth the price and very easy to install nad every thing fit like a glove.
