Steering Pump Or Not Steering Pump problem..


HELP... Before i go a pay stupit money on a steering pump on the advice of a Main dealer..

Steering is Quite Heavy (Not like there is no Assistance from the power steering pump which you can hear as you turn the wheel ) but heaver then it should be, Main Dealer insistes its the Steering pump but if you try to turn the wheel without the engine on it even Heavier but with the engine on it its a lot lighter to turn but heavier then it should , it also wont return to centre when you go around a corner it's progressivly harder to turn at say 1/2 turn ether left or right,

1. steering is very heavy (but you can hear the pump working as you turn the wheel and when you go full lock )
2. pump much be doing somthing as it not as hard to turn as it is with the engine off.
3. steering wheel wont return to straight ahead when you complete a turn.
4. stearing feels harder to turn at different spots as you turn the wheel.

any thing i can check or is there a way to check if the pump is 100% ok....

I have just recently been down this path and in the end, the pump is shot and you need to replace it. If your doing it yourself for the 1st time, work on around 3-4 hours to do the complete job and make sure you use the correct power steering fluid when you refill it.

My pump was heavy steering and when it was running was OK but after 5 mins in traffic, the pump would cut out and I would have no power steering. After 5 mins to allow it to cool, the pump would work. My tell tale was either sudden heavy steering or I couldn't hear the pump running and knew what to expect.

If your doing it yourself, jack the car up as high as the jack stands allow to gain access to the two rear bolts you will need to remove and replace the low pressure hose clamps with screw tightened clamps, the OEM clamps are rubbish. Also replace the O-ring to the high pressure pipe.

In regards to the steering getting harder after 1/2 a turn, mine was the same with the faulty pump stopped as there was no way for the fluid to be transferred so there will be a pressure build up with the fluid being unable to circulate.
