power steering only works when motor is running. If car is running and you are having this problem it could be as simple as low power steering fluid...have it check...good luck and hope this helps some.

If it starts shaking after 100kph then its either the power steering pump or the steering box is going bad. Do you hear wizzing noises when you turn the wheel right and left (similar to a turbo boost sound)? Have you recently notices problems with steering like being delayed?

The only other thing that would cause something like that would be if the tires are worn badly on places. If this was the problem, it would not really shake the wheel - but when the tires hit a bump or notch in the road it would allow them to go in that direction easier then usual. So it would seem like something was grabbing the wheel or changing the course while driving.

If you steering box is going bad, you will notice other things like a delay from when the wheels start to respond after you have turned your steering wheel in a certain direction. if your turning right and there seems to be a delay as to when your wheels begin to turn then you need to have the box checked.

After checking the box if that is not the problem, try adding power steering fluid and see if that fixes the problem. If it doesn't then have the power steering pump checked.

Check the power steering fluid level.
If the fluid level is low, you obviously have a leak somewhere and it should be repaired. If the level is up, watch the power steering pump while the engine is running; is the pulley turning freely?
Power steering systems are hydraulic devices. The pump provides the pressure and the steering gear or rack and pinion assembly (depending on the vehicle type) applies pressure in the direction that you are turning the wheel to assist with the steering. When the hydraulics fail or when the internal components fail, your strength is the only thing turning the steering.
But start with the fluid.

If the car dose not make any type of noise when you try to start it is is a power issue and you should check your battery and wiring to make sure there is no lose wires. if it dose make some sort of noise please respond with what type of noise it makes and I will do my best to point you in the correct direction.

Thank you hope this helped.

CHECK POWER STEERING FLUID IT COULD BE TOO LOW.OR YOU HAVE INCORRECT TIRE PRESSURE.LACK OF LUBRICATION AT STEERING JOINTS.YOUR FRONT END OUT OF ALIGNMENT.YOU COULD HAVE A FAULTY POWER STEERING PUMP.OR YOU HAVE A LOT OF AIR IN POWER STEERING SYSTEM.YOU HAVE TO BLEED AIR OUT OF POWER STEERING PUMP.CHECK POWER STEERING PUMP HOSES.MAKE SURE.NONE ARE LEAKING OUT FLUID.

Hello altgraph1: My name is Roger and I can help. The power steering and the brakes are directly connected. If the power steering pump fails you will also loose the brake assist. This vehicle does not have a vacuum booster you have a hydro-boost brake system. This unit uses the power steering pressure to assist the stopping of the vehicle. You will need special tools to determine if the power steering pump failed or if the hydro-boost system failed. Most likely the power steering pump failed. How ever to be sure it should be tested first. Should you need further help please just ask. Please rate the answer you received. Thank You for using Fix Ya. Roger

this power steering pump has been a problem from the start. I have seen them replaced alot. They run about 50$ new, and are a easy fix. As far as it running ruff, have you ever tuned it up?

you have to bleed the power steering system. you have someone turn the wheels to the left while you watch the power steering fluid level adding as needed. than repeat turning the wheels to the right. and repeat until the noise seems to get quieter and you don't have to ad any more fluid.


hope this helped
please rate well

it seems your have a power steering problem. it could be a simple fix by checking the power steering resevoir for proper fluid level. it also be that the steering pump is failing. the most troublesome is that the rack and pinion unit is the fault. first thing to check is the fluid resevoir if it's low fill to proper level and start the vehicle. turn the steering wheel all the way left and hold till you hear a light squeal, then turn to the right and hold till you hear the squeal. do this several times. this is to make sure there is no air in the system. you should be able to turn the wheel and it should be smooth with no hesitation. if this doesn't solve the problem, then you must take it to a shop to have the pump replaced if it is the fault or the rack and pinion............please rate the solution...thanks
