How does the torsion bar work on a car?
How does the torsion bar work on a car?
As the wheels travel up and down, the control arm or knuckle pushes against the torsion bar, but, because the torsion bar is held firm to the chassis, it doesn’t move up and down. Instead, the control arm or knuckle pushes on the torsion bar like a lever, twisting it.
How do you remove a lower control arm?
Grasp the sway bar link and remove it away from the lower control arm mount. This will help the sway bar link stay out of the way during the job. There will be two control arm mounting bolts which could be horizontal or vertical. Use a 19mm to 22mm wrench or socket to loosen and remove the bolts.
How is a sway bar connected to a lower control arm?
A sway bar will be connected to the control arm by way of the sway bar link. Remove the nut using a 14mm or 15mm wrench or socket. There could be a mini taper fit for this connection so you may need to shock it loose much like the ball joint. Grasp the sway bar link and remove it away from the lower control arm mount.
How is a torsion bar different from a coil spring?
That’s just what a torsion bar does. That twisting pushes back against the control arm or the knuckle, just like a coil spring would push back. Just like coil springs, torsion bars require the use of a shock absorber to act as a damper. Otherwise, there would be too much bounce in the spring.

How do you replace lower control arm joint?
With tension now removed from the torsion bar, loosen the 24mm nut at the bottom of the wheel knuckle that holds the lower control arm ball joint in place. Don’t remove the nut, but leave a large gap between the nut and the wheel knuckle. Figure 6.

What to do if your torsion bar breaks?
To see if the torsion bar is really the cause of your problem, you can visually inspect it. With gloves on, run your hand along the torsion bar and feel for rust. Look for any cracks in the torsion bar. Cracks, if left alone, can eventually break the torsion bar right in two.
