The front suspension on a Ford Explorer is a bit different than most because instead of using a traditional coil or spring to control the height, it uses a torsion bar, which acts as the spring by twisting. They need adjustment occasionally, because the truck sags to one direction or another. To adjust the torsion bars, it takes the right tools plus an hour or so of your time.
Measure the distance from the ground to the top of each front fender well using the tape measure; record these numbers.
Lift up the front of the vehicle using the jack and secure it on jack stands. Make sure the vehicle is completely secure on the jack stands.
Crawl underneath the vehicle and locate the torsion bar crossmember. The torsion bars are long bars that run the length of the vehicle and connect to the lower control arm as well as a crossmember in the middle of the vehicle. On this crossmember are a pair of adjustment bolts that hold the end of the torsion bar in place. By tightening these bolts, you can lift the front suspension, and by loosening them, you can lower the front suspension.
Place the 1/2-inch ratchet and socket onto the torsion bar adjusting bolt. If you need to raise the suspension, tighten the bolt. If you need to lower it, loosen the bolt. Only turn the bolt a few turns at a time, you don't want to completely remove the bolt.
Lift the vehicle off of the jack stands and measure the distance between the ground and front fender wells using the tape measure and compare these numbers to your previous numbers recorded on the paper. If you need to adjust the height further, repeat Steps 2 to 4 and adjust accordingly.
