There are many types of ‘bushings’ used in cars, such as: control arm bushings, leaf spring bushings, shock absorber bushings, steering rack bushings, and more generally, suspension bushings.
Essentially, bushings absorb the vibration and noise from the suspension system, limiting the transfer to the vehicle and controlling the amount of movement.
Control arm bushings are located between the control arm and the frame of the vehicle. They are important for tire alignment and directly affect tire wear, handling, and vehicle control.
Most cars use one or two control arms per wheel, on both the front and rear suspension, with each arm housing two bushings. Most front-wheel drive cars only use a lower control arm, whereas most pickups, trucks, and SUVs have both an upper and lower control arm. Typically, there is a ‘big’ arm bushing and ‘small’ arm bushing for each arm.
Leaf spring bushings or spring shackle bushings are another kind of bushing, located in the ‘eyes’ of the leaf spring. Leaf springs are typically used in the rear suspension of heavy-load bearing vehicles such as pickups and trucks.
The leaf springs support the weight of a vehicle and control the ride height, while keeping the tires in level contact with the road. As a result, the load on leaf spring bushings are very high due to the weight and forces involved with heavy duty vehicles and need to be changed regularly.
Stabilizer bar bushings are a further type of bushing used in vehicles. They are mounted underneath your car on anti-roll bars which prevent excessive vehicle roll (from side to side) especially as you turn.
As a result, they are constantly twisting and flexing, and can wear more rapidly due to contact with oil, grease and dirt. Usually, there are two stabilizer bars per vehicle (front and rear), each with two stabilizer bar bushings.
As with all our parts, Mchanix uses high quality materials such as virgin natural rubber and high-grade steel to manufacture premium quality bushings that isolate NVH, to support great driving comfort and vehicle safety.
