Steering rack (rack and pinion)

The rack that turns the steering wheel's rotation into side-to-side movement of the track rods, and on most cars provides the power assistance too.

Also called steering gear, rack.

How you know it is this

  • Fluid leaking from the rack gaiters or the pipe unions
  • A knock through the wheel over bumps
  • Assistance that comes and goes, or is heavier one way than the other
  • A whine that tracks steering effort rather than engine speed

Worth knowing before you buy

  • Hydraulic and electric racks are completely different parts. Newer cars are electric and have no pump, hoses or fluid at all.
  • An electric rack usually has to be coded to the car after fitting.
  • A leak at the gaiter can sometimes be an inner tie rod rather than the rack itself, which is far cheaper. Worth establishing first.
  • Alignment afterwards, always.

What we need to quote it. Whether the car has hydraulic or electric power steering, and whether it is 4MATIC — the rack differs. 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.
