Toyota Control Arm
Even if your Toyota is well equipped with the most powerful engines to grab maximum horsepower, torque and zero-to-60 acceleration, still for a good driving you need a complete control on your Toyota. Each and every Toyota models like Toyota Prius, Toyota Sienna, Toyota Highlander, Toyota Tacoma…etc has suspension both at front as well as rear side of the Toyota to give a controlled driving direction. Let's understand the basics of suspension and explore information about the control arm, by taking a look in the world of Independent Suspension.
Significance of Suspension in your Toyota
The dynamics of your moving Toyota can be tartan by its ride and handling quality. Ride quality refers to Toyota's ability to smooth out the inevitable bumpy road if any; whereas handling quality refers to the safe acceleration, braking and cornering. Toyota manufacturers are driven to design the suspension to provide such qualities, by keeping three major principles in the mind.
These principles are:
- Road isolation: Helps in isolating jerk of a bumpy road from the passenger carriage.
- Road holding: Ability to steer, brake and accelerate due to the friction produced between the tires and the road; also, helps your Toyota to maintain a straight line motion with its grip on the road surface, irrespective of different directional changes.
- Cornering: Ability to travel a curved path smoothly and by maintaining a proper balance in your Toyota.
As your Toyota axle is a four-wheeler, its front wheels are linked to front axle whereas rear wheels are linked to rear axle. So, one may guess two different (front & rear) suspension working in your Toyota which may further be sub-grouped as dependent & independent suspension.
Types of Automotive Suspension:
- Dependent Front Suspension (DFS)
- Independent Front Suspension (IFS)
- Dependent Rear Suspension (DRS)
- Independent Rear Suspension (IRS)
Outstanding and satisfactory performance of Toyota's suspension can be carried further by its reliable and durable suspension parts. One such important part of the suspension system is Toyota Control Arm.
What is a Toyota Control Arm?
A control arm or a wishbone or A-arm is a system of linkages which is virtually flat, bar shaped triangular sub-frame with three strong points (two at the foot, attached to the frame; one at the apex, attached to the spindle) and is meant to pivot at two ends: The wide end is pivoted on a bushing and the tapered one on a ball joint.
A-arm is positioned in between the frame and rear axle to connect different suspension features to the chassis of the Toyota. It is designed in such a way so that it may carry away the flexes of control of your beauty, simply by carting brake and transmitting torque. Apart from this, it yields a better traction to the tyre for a strong adhesion to the ground. In a way, Toyota control arm helps your Toyota wheels to maintain a drive as per the Toyota car body. Two A-arms per wheel results into a double wishbone suspension whereas one per wheel will make up a lower part of Mac Pherson strut suspension or any other similar structure.
Symptoms of a faulty Toyota Control Arm
- Worn-out or oblong shaped control arm bushings in one or both sides of the Toyota, may give you a feel of high vibration, or a clunking sound while going over bumps.
- Vibration in your Toyota may happen because of axial or radial play of the wheels due to the loose or tattered ball-joint.
To have the benefit of a worry-free and hassle-free driving experience, it is recommended to check Toyota control arms at a regular interval of time and in case of any damage, rush for an instant replacement as soon as possible.
