Suspension Control Arm Bushings Replacement
What are control arm bushings?
The control arm bushings are a component of the control arm, which lets the wheel travel up and down over bumps. The bushing in particular let the control arm pivot.
How do control arm bushings work?
Control arm bushings are found between the control arm and the body or suspension subframe. The bushings help distribute impact force and absorb vibration.
What are the symptoms related to a bad control arm bushing?
If the bushings are worn out, the suspension will make a squeaking sound when going over bumps. If they are severely worn, a knocking sound may be heard as the control arm makes metal-to-metal contact with the bushing bracket.
With severely worn bushings, tire wear may be uneven and the vehicle may pull to one side or wander.
Can I drive with a control arm bushing problem?
If the control arm bushings are worn, the result will be an annoying squeak when the car goes over bumps. In this case, the car can be driven. But if the bushings wear out considerably, metal-on-metal contact may occur and cause further suspension damage and inconsistent handling. This requires a repair.
How often do control arm bushings need to be replaced?
While there's no set schedule, the bushings may wear out and need to be replaced as a vehicle approaches 100,000 miles. Driving aggressively or over rough roads can decrease the lifespan of the control arm bushings.
On some vehicle models, the bushings are permanently installed in the control arms. If the bushings wear out, the entire arm will need to be replaced.
