CHECKING FOR WEAR OF POWER STEERING PUMP INTERNAL COMPONENTS
1.
Place gear selector in PARK (or NEUTRAL) with wheels chalked.
2.
With the engine idling, have a helper turn the steering wheel.
3.
Using an electronic listening tool, determine if noise is coming from the pump.

(Refer to 19 - STEERING/PUMP - REMOVAL)
CHECKING FOR POWER STEERING HOSES TOUCHING BODY OR FRAME OF VEHICLE
Check hoses and hose tubes as following:
-
Inspect hoses and hose tubes for witness marks. If witness marks are present, adjust hose(s) to the proper position by loosening, repositioning and tightening attachments to the specified torque
(Refer to 19 - STEERING/PUMP - SPECIFICATIONS). Do not bend tubing to adjust. Replace the hose assembly if damaged.
-
Check fastener torque of hose mounting brackets and tube nuts.
(Refer to 19 - STEERING/PUMP - SPECIFICATIONS)
-
Have a helper bump the steering gear off of the stops to induce pressure fluctuations which may move the hose. If hose contact is made, adjust hose(s) to the proper position by loosening, repositioning
and tightening attachments to the specified torque
(Refer to 19 - STEERING/PUMP - SPECIFICATIONS). Do not bend tubing to adjust. Replace
the hose assembly if damaged.
