2003 SILVERODO 1500 4X4 IS REAL HARD TO TURN TO THE RIGHT
If you keep the wheels on the ground, the remaining air will be injected into the fluid at high pressure and will cause the fluid to foam. It can take several hours for the air and fluid to separate, so you want avoid doing that. Raise the wheels off the ground, fill pump with fluid. BEFORE STARTING THE ENGINE, turn the wheels back and forth GENTLY a few times. Refill with fluid, again turn wheels back and forth a couple times, refill with fluid. Start your engine, then check fluid level, refill as needed. Then turn wheels back and forth a couple times, check fluid level. If no more needs to be added, test driving at slow speed and top off the fluid if need be afterwards.
It's possible the valving in the rack is messed up
Most are pretty durable and last upwards of 100,000 miles. But, sooner or later, all racks succumb to leaks or wear. Common problems that afflict power racks are contamination, "morning sickness" and center wear. Contamination can occur if the power steering pump is failing, if the hoses are deteriorating, or if the fluid is contaminated by moisture or other substances. Morning sickness is a condition where the steering feels stiff when the car is first started on a cold morning. Normal power assist does not return until the car is driven awhile and warms up. This problem is most common in Saginaw racks , is caused by wear in the spool valve housing. Center wear is caused by wear between the rack and pinion gears, and can allow steering wander when driving straight ahead. Power racks can also develop fluid leaks. Seal wear can allow fluid to seep out of the power cylinder into the end bellows on the rack. The bellows are not designed to hold power steering fluid. The presence of power steering fluid in either bellow, therefore, means the rack is leaking internally and needs to be replaced. If nothing is done about the problem, the bellows will continue to mushroom with fluid until one or the other bursts, releasing the fluid that has been mysteriously disappearing from the pump reservoir. And I think this may be more confuesing then a help.
WHAT IF WE DON'T HAVE RACK AND PINION AND HAVE PUT NEW POWER STERRING PUMP ON ALSO?
What do you mean you don't have a rack and pinion?
The. Only other thing I can tell you is possibly you have the lines installed backwards. On some models the inlet and Outlet lines are the same size if you accidentally cross them it will violently pull to the right.
