| Extraneous noise when operating the steering wheel | Hissing sound in steering gear All power steering systems produce some additional noise. One of the most common is a hissing noise when the steering wheel is turned with the vehicle stationary. This noise will be most noticeable when turning the steering wheel while the brake pedal is depressed. There is no relationship between this noise and the operation of the steering. Do not replace the valve unless the "hissing" noise becomes extreme. A new valve will also make a slight noise. | |
| Rattling sound in steering gear | Play between the hoses and the car body | Route and secure hoses properly |
| The steering gear is loose. Secure the steering gear | Secure the steering gear | |
| Loose tie rod end and/or ball joint | Tighten the connections | |
| Worn tie rod end and/or ball joint | Replace | |
| Noise in the power steering pump | Low fluid level | Add liquid |
| Air in liquid | Remove air | |
| The pump mounting bolts are not tightened | Tighten the bolts | |
Warning! A low noise should be heard immediately after starting the engine at an air temperature of -20°C. This is due to the properties of the fluid used in the power steering and is not a sign of a malfunction.
