Refer to owner’s manual or manufacturers specifications to determine the correct fluid to be used in the power steering system.
**ONLY USE RECOMMENDED FLUIDS. **
Other steering components may retain residue or debris from the old system and contaminate the new rack immediately voiding the warranty.
A leading cause of malfunctioning units is hose residue in the system. Hoses don’t just “up and break”. They deteriorate, they rot, they break away and they slough off pieces of rubber residue. In turn, pass through the system to plug up or gum up the valves and orifices in the rack and pinion unit.
Since hoses deteriorate from the inside-out, it is sometimes difficult to tell if they are failing just by carrying out a visual inspection. If the hose feels stiff, hard or spongy – replace all hoses in the system. Here’s why: the hoses are all made from a similar compound. If one hose is in poor condition or rotten, it is a sure sign that they are ready to be replaced.
NB: SOME FORD PUMPS ARE VERY DIFFICULT TO BLEED. AIR GETS TRAPPED IN THE SYSTEM. THE RESULT IS A GROWLING NOISE FROM THE PUMP. MAKE SURE ALL FITTINGS ARE AIRTIGHT BY LOOSENING SLIGHTLY AND RE-TIGHTENING TO MANUFACTURERS TORQUE SPECIFICATIONS.
