How Control Arm Bushings Affect Your Vehicle
Control arm bushings are an important part of vehicle suspension systems. Bushings are made of rubber which separates the faces of two objects while allowing a certain amount of movement. As a car moves over tough or bumpy surfaces, this movement allows the suspension parts to move easily. The rubber, which is flexible by nature, helps to minimize transmission of noise and small vibrations through to the chassis of the vehicle.
Bushings are made through hot-bonded construction where elastic material is melted to the inner and outer metal sleeves. Another method used for producing bushings is whereby the elastomer or rubber material is injected in the sleeves. Polyurethane or synthetic rubber does not bond to metal; it remains suspended on the mount surface which allows a greater range of motion.
The rubber material is placed around a small metal cylinder that allows for a small bolt to pass through it. As rubber wears out over time as a result of heat and frequent movement, it is advisable to check bushings regularly for damages to prevent failure.
Functions of Bushings
Bushings press into control arms at each end of the device to secure the connection to the chassis. The control arm is the device that connects suspension system to the chassis of the vehicle. Control arm bushing is used to hold the bolt in place that connects the control arm to the chassis. They are located at the broad end of the control arm to which the part pivots.
Effects of Bushings
Bushings are installed at the front and rear suspensions of vehicles which helps to maintain proper alignment while driving. This is achieved even on off road and under extreme weather conditions. The presence of control arm bushing in the suspension system enhances navigation and safety features of the vehicle. As a result, there is an overall improvement in handling, cornering and control. This also enhances driving experience as it provides smooth operations.
Installing high quality bushings lightens up handling. In a car’s suspension, three or four control arms are installed between the rear axle housing and the frame to carry the brake torque. Control arms are used to save weight and add adjustability which enhances suspension performance. Therefore installing quality bushings complements these functions and makes it easy to maneuver uneven road surfaces or when driving in extreme weather conditions.
Controlled Wheel Hop
Another benefit of bushings is that they are useful in controlling wheel hop which also improves cornering control. They help in maintaining proper alignment which allows good steering response and greater control of the vehicle.
Installation of Control Arm Bushings
It is important to install high quality bushings as they are durable and reliable. Pre-lubricated designs also support lowered or raised cars where geometry has been altered. When installing bushings, inspect other components in the suspension system to minimize damage, wear and eliminate failure. This should be done in both loaded and unloaded modes.
