Damage to the power steering is caused by a lack of oil in the hydraulic system. Even small leaks can lead to loss of fluid owing to the high oil pressure in the hydraulic circuit, thus resulting in damage to the power-steering pump.

Grunting noises when the steering is locked or foam production in the supply reservoir indicate insufficient oil and/or sucked-in air. However, before the supply reservoir is topped up, any leaks on the suction side must be remedied or the damaged part replaced on the pressure side.
