Mercedes Control Arm---taking Matters Into Its Own Hands

By: Dwyane Thomas

The one that is responsible for the precise control, handling, and balance of the drivability of the Mercedes Benz is the control arm. Otherwise called as the wishbone or A-arm of the suspension system, the Mercedes control arm is nearly a flat and roughly triangular member (sub-frame) that pivots in two places. Its broad end is attached at the frame and pivots on a bushing. While the narrow, on the other hand, attaches to the steering knuckle and pivots on a ball joint.

Up to four control arms are fitted to the region between the Mercedes' rear axle billet and frame. The lower control arms provide the suspension setting parts with a rotational movement whenever the car is cornering. This results to complimenting the suspension system in dispersing chassis flex for a convenient traveling pleasure.

These Mercedes control arm also makes the coil springs to respond to the axle and wheel assembly treading through bumps and potholes. The pivots at the other end of the control arm (which attaches the parts to the chassis) allow for the up and down motion of the coil springs to absorb the shocks during bumps.

To allow for a steady and comfortable feel during travel, the Mercedes control arm synchronizes all four tires to the motion of the vehicle. It is built with cylindrical bushings for a less-friction feature to enhance handling. It also improves steering and less tire wear-out with the less-traction contact surface as the rubber meets the road.

Bearing the brunt of these kinds of pressure constantly and regularly will result to the wear and tear of the . Thus, there are control arms which come in twos to share the pressure of dispersing flex across the chassis. Though it proves its durability, it will eventually come into deterioration with rut and flex. To maintain the peak performance of the suspension system, regular check ups and replacements (if the state worsens) must be conducted for more pleasurable and comfortable Mercedes ride.
