STEERING PUMP ETC

Steering problem
2004 Dodge Caravan 6 cyl Front Wheel Drive Automatic 51000 miles

Hi!
Steering pump was changed on my 3.3: V6 (similar to 3.8L) due to squeeking noice.
The squeeking noicse continous when turning the steeringwheel. The container is filled to the maximum when engine is off.
Why is there still a squeeking noice? Does it still contain air in the system? If so how EXACTLY do you air it? The description of airing is basically. Lid on. Keep the wheels straight for a while and then turn them left and right without hitting the end of turn. What to do?

BLEEDING THE SYSTEM TO REMOVE AIR

After filling the system, you will have to bleed the system to remove trapped air. This is done by raising the front wheels off the ground, then slowly turning the steering wheel from side to side six to 10 times with the engine off. Do not turn the wheel too rapidly or allow the pump reservoir to run dry. Continue cycling the steering back and forth until no more bubbles can be seen in the fluid reservoir, and the reservoir level remains steady.

Next, disable he ignition and crank the engine over several times while observing the fluid in the pump reservoir. If you see any bubbles or foaming, continue cycling the steering wheel back and forth (engine off) until all of the air is out of the system. Make sure the fluid reservoir is full when you have finished.

On some systems, the use of a power steering pump air evacuator (Devac tool) is required to purge the air from the system.

Other probable area could be a rack and pinion

What is the pinion and rack?

A rack-and-pinion gearset is enclosed in a metal tube, with each end of the rack protruding from the tube. A rod, called a tie rod, connects to each end of the rack.

The pinion gear is attached to the steering shaft. When you turn the steering wheel, the gear spins, moving the rack. The tie rod at each end of the rack connects to the steering arm on the spindle

The rack-and-pinion gearset does two things:

It converts the rotational motion of the steering wheel into the linear motion needed to turn the wheels.
It provides a gear reduction, making it easier to turn the wheels.
On most cars, it takes three to four complete revolutions of the steering wheel to make the wheels turn from lock to lock (from far left to far right).
