If your Rancho struts are in need of adjustment, there are a few things you'll need to do. First, you'll want to raise the front of your vehicle so that the front wheels are off the ground. Next, you'll need to locate the adjustment nut on the top of the strut. Once you've found it, you'll want to use a wrench to turn it clockwise or counterclockwise, depending on which way you need to adjust the strut. Finally, lower your vehicle back down and test out the new setting before driving on any rough roads.
