There are three types of power steering systems used on passenger vehicles. The first and most popular
is known as power rack-and-pinion steering. It utilizes a power unit built directly into the rack assembly.
When the wheel turns, an internal rotary valve directs the flow of power steering fluid to the proper end of
the power cylinder. The difference in pressure on either side of this cylinder assists in moving the rack,
thereby easing steering. A control valve then returns excess fluid to the main reservoir.

A common cause for loss of power steering and the fluid is a power steering
hose under the car. As viewed from underneath, on the v6 there is a small 4
in. hose that connects 2 pipes. It is at the intersection of the rt. (passenger
side) frame rail, and the rear framerail. A new hose and clamps are needed.
Then fill and bleed the system.
On the v8 models, the entire hose / pipe assembly must be replaced. This is
quite a big job. The frame needs to be lowered and an engine mount
removed. Then fill and bleed until the whining goes away.
Best way to bleed is to get the front wheels off the ground, fill the reservoir
half way, turn the steering wheel to the rt. Then to the left- all the way to the
stops. Do this 10-15 times. Check and adjust fluid level, then start the car.

| This recall has since ended. Just go to any shop and have them fix it for you. Cost is minimal because it is suck a small hose and takes only a few minutes on the V6 engine. |
| 2-6-12 WHAT IS THE COST TO FIX IT ON A V8 ENGINE. |
| Expect to pay about 2 1/2 hours shop labor plus about $175 for the steering hose assembly. |
