Control Arms

 

Control Arms

Control Arms act as a pivot point for the tires by fixing steering components to the vehicle. There are two basic designs, the wishbone (two points of attachments) and the single pivot design. Ball joints can be pressed in or bolted on to the control arm.

What is a control arm and how does it work

What is it?

  • The wishbone style control arm is more stable in lateral movement than single pivot design.
  • Single pivot control arm design is lighter and takes up less room than the wishbone design, but needs additional components to get the same lateral movement experience as the wishbone design.

How Does it Work?

  • Control arms fix steering components to the vehicle and act as a pivot point for the tires.

How is it Made?

  • Control arms are cast as either forged steel or aluminum.

Why Does it Fail?

  • Control arms fail when they are worn out or damaged.

What are the Symptoms of Failure?

  • Increased tire wear.
  • Uneven tire wear.
  • Clunking noise on bumps or turns.
  • Front end shimmy.
  • Hard steering.

What are the Implications of Failure?

  • Angle of the tire can cause an abrupt halt or tire damage
  • Debris can cause damage to others.

How Difficult is the Install?
