Control arms — upper and lower

The arms that locate the wheel to the car and let it move up and down while staying pointed the right way.

Also called wishbone, control arm, A-arm.

How you know it is this

  • Knocking over bumps, worst at low speed
  • Steering that wanders or tramlines
  • Uneven tyre wear on the inner or outer edge
  • The car failing to hold an alignment

Worth knowing before you buy

  • A Mercedes front end typically uses several arms per side, and the fault is usually in one of them. A diagnosis that names the arm saves buying the set.
  • Many arms are supplied with the ball joint and bushes already pressed in, which is usually the cheaper route once labour is counted.
  • Always needs a four-wheel alignment afterwards. Budget for it — skipping it ruins tyres quickly.
  • 4MATIC front arms differ from rear-drive. Confirm which the car is.

What we need to quote it. Upper or lower, front or rear, left or right, and whether the car is 4MATIC. The chassis number settles the generation, the body and usually the engine in seventeen characters — it is on your mulkiya. A photograph of the old part helps where there is more than one version.
