I concur with everything that has been written. I would add that to adjust the height, you need to realize that the adjuster on the driver side raises/lowers the passenger side and visaversa. Also, you need to make the adjustment and then back the truck out of the garage and back in. Otherwise, the setting does not remain where you had it when you first lowered the front tires back to the floor. Also, use a ratchet with a small extension so you do not scrape the skin off of your knuckles when the wrench slips off!
