If you feel or hear any knocking or rattling noises from the steering or suspension, you should seek advice. Excessive movement or play in the steering wheel may indicate wear in the steering mechanism. You should seek qualified advice without delay.
When the ignition is on and/or the engine is running, movement of the steering wheel will cause hydraulic pressure or electrical energy to assist the driver and make the steering easier. If the steering needs a lot of effort (becomes heavy) the powerassistance system may not be working properly.
Before starting a journey, two simple checks can be made.
Check the level of fluid in the pump reservoir regularly when the engine is switched off. The level should be between the ‘min’ and ‘max’ marks.
Never run the engine without oil in the pump reservoir. You could severely damage the pump or cause it to seize up completely.
Check the condition of shock absorbers by examining them for signs of fluid leaks and by bouncing the vehicle. It shouldn’t continue to bounce unduly when tested. If in doubt, seek qualified help.
Worn shock absorbers make a vehicle difficult to control and can increase your stopping distance.
