Chevrolet Repair: power steering noise

Question
When I turn the car the power steering sometimes makes a slight noise.
A mechanic says that the p/s needs to be bled, but going to a shop another mechanic there says they no longer do it because all new cars have an automatic bleed on them.

I wonder how I can engage the bleed mechanism or do I need a new part on the system?

Answer
HI MATTHEW,,OK WE WILL SET THIS RECORD STARIGHT..THERE IS NO WAY TO BLEED YOUR SYSTEM. OTHER THEN MAKING SURE THE PUMP RESERVOIR IS FULL OF FLUID. THIS WILL SELF BLEED ITSELF...MAKE SURE SYSTEM IS FULL AND TURN THE WHEEL LEFT AND RIGHT ABOUT 15 TIMES. THIS WILL BLEED ALL THE AIR FROM THE SYSTEM...IF THERE IS A NOISE IN THE PUMP LIKE IT IS LOW ON FLUID A [WHINING NOISE]THE PUMP IS GOING BAD OR THERE IS ALOT OF STRESS ON THE POWER STEERING SYSTEM. COULD BE CAUSED BY THE STEERING LINKAGE STARTING TO BIND UP..SUCH AS BAD BALL JOINTS,TIE ROD ENDS,UPPER STRUT TOWER MOUNTS. ETC..I DO NOT KNOW WHAT YEAR OR WHAT KIND OF CAR YOU GOT SO IT MAY NOT HAVE STRUTS...JACK THE FRONT OF YOUR CAR UP SO THE WHEELS ARE OFF THE GROUND. MAKE SURE CAR IS OFF THE GROUND, NOW GRAB THE LEFT OR RIGHT TIRE AND MOVE IT FROM LEFT TO RIGHT. THIS SHOULD TURN BUT NOT REAL REAL HARD...IF SO SOMETHING IS BINDING UP..CK IT AND REPLACE IT.IF IT TURNS OK THE PUMP IS FAILING....GOOD LUCK TO YOU TOM..
