In this video, we're gonna be working with our 2001 Ford Ranger 4WD. We're going to show you how to remove and replace a torsion key. You may need to do this if you're installing a leveling kit in your vehicle or if you've removed a torsion bar or lower control arm and the old one was damaged or seized during the procedure. This job does require some special tools and is under very high tension, so please be sure that you are properly equipped and confident before performing this repair safely.

Here are the items you'll need for this repair: 13-19mm sockets, ratchet, socket extension, braker bar, pry bar, hammer, two-jaw puller, rust penetrant, marker, flat blade screwdriver, safety glasses, gloves, jack and jack stands

Using a flat blade screwdriver, remove the center cap from your wheel. Using a 19 millimeter socket and breaker bar, loosen your lug nuts one turn. We have a wheel lock on ours so we'll be using a wheel lock key to remove it. Raise and support your vehicle.

We're using a lift, but this job can easily be done in the driveway with a jack and jack stands. Finish removing your lug nuts by hand. Remove your wheel and tire from the vehicle.

Your torsion bar is the spring suspension for the front end of the vehicle. We're going to index where it goes into our lower control arm here just to make sure that everything goes back in the same way it came out. Now we know to make this side of the arm match there. At the rear of the torsion bar is what's called the torsion key, which this bolt tightens and loosens that key to add more or less tension to the bar. We'll index the key to the back side of the bar, as well just to make sure everything goes together the same.

This 13 millimeter bolt and this access panel here is what tensions the key for the torsion. What we're going to do is make sure we count the number of rotations to remove it so we can install it the same number of turns. One, two, three, four, five, six, seven, eight, nine, ten, eleven, twelve, thirteen, fourteen, fifteen, sixteen, seventeen, eighteen turns. Remove this cover with the two 13 millimeter bolts at the top and two more at the bottom. Be sure to hold onto this cover when you remove the last bolt.

Removing the keeper from the torsion bar and key is a high-tension and a potentially dangerous procedure, so be sure to wear proper safety equipment during this step. This divot in the torsion key is designed to have a two-jaw puller set into it, set the jaws on both sides of the cross member, and install the forcing screw into the divot. Using the appropriate size socket for your particular two jaw puller and a breaker bar, add tension until this keeper can be removed. Once the key has been moved up and off of the keeper, lift up and slide the keeper out of your cross-member then carefully loosen the two-jaw puller until all of the tension is off of the key. Now that the tension is off of your bar, you can tap the key off the end of your torsion bar with a hammer.

We soaked our torsion key in penetrating oil and now we're going to pry it down with a pry bar. Tap it loose. We have this little cover up here that we can pull down and then remove the key from the torsion bar and remove our pry bar. Line up your indexing marks and reinstall your torsion key onto the other end of the bar. Reinstall the two-jaw puller into the divot on your torsion key. Again, make sure it's on there nice and secure. Use your proper safety equipment and a 16 millimeter socket and ratchet for our particular puller. Run that torsion key up until we can get our adjuster block back to the cross-member. Once it's through, reinstall the adjuster block and its channels into the cross-member and carefully lower the torsion key back onto it.

Reinstall the cover and three 13 millimeter bolts. Tighten the bolts down with a 13 millimeter socket and ratchet. Get the bolt in by hand for your adjuster block just until it touches the bottom of your torsion key at which point we use the 13 millimeter socket and ratchet to install the exact same number of turns we used to remove it.

Reinstall your wheel and tire onto the hub and get your lug nuts on as tight as you can with the wheel in the air. Put the weight of the vehicle back onto the tires. Now we'll torque our lug nuts to 100 foot-pounds in a cross-pattern making sure you end with your locking wheel lug if you have one. Again, these are a 19 millimeter. Line up the tabs on your center cap. Place them over the lug nuts. Tap it into place.
