Power Steering (P/S) System Leaking and/or Noisy – 2006-2009 Ford Focus

POWER STEERING – LEAK / NOISY

 

FORD:

2006-2009 Focus

 

2006-2009 Focus vehicles built on or after 10/3/2005 may experience a customer concern of the Power Steering (P/S) system leaking and/or system noisy.

 

This may be due to a damaged O-ring seal at the P/S reservoir-to-pump body causing a low fluid level or fluid aeration.

 

ACTION:

Follow the Service Procedure to replace P/S pump reservoir-to-pump body O-rings.

 

SERVICE PROCEDURE

NOTE: IF ANY P/S SYSTEM COMPONENTS HAVE BEEN RECENTLY SERVICED OR THE SYSTEM HAS BEEN OPERATED BELOW THE MINIMUM FLUID LEVEL, THE P/S SYSTEM PURGING PROCEDURE SHOULD BE COMPLETED PRIOR TO PERFORMING THIS PROCEDURE.

1. Inspect P/S system fluid level.
   1. If fluid level is low, proceed to Step 2.
   2. If fluid level is okay, proceed to Step 3.
2. Inspect P/S system for a leak condition at P/S fluid reservoir-to-pump attachment for signs of leakage.
   1. If found, proceed to Step 3.
   2. If no leak is observed at this connection, this procedure does not apply. Refer to the Workshop Manual (WSM) for normal diagnostics.
3. Remove the P/S fluid reservoir. Proceed to Step 4.
4. Inspect P/S pump reservoir inlet bore for burrs or damage.
   1. If minor burrs are found, these may be corrected by using fine grit (240 or finer) emery paper (obtain locally).
   2. If larger burrs or damage is found, replace P/S pump.
   3. If inlet bore is free from burrs or damage, replace reservoir O-rings.
5. Lubricate the O-rings with MERCON V or equivalent. Reinstall P/S pump and reservoir assembly.
