Drunken steering I have a 1997 Safari with hydraboost steering or adaptive sterering the first Year they put this in the Safari. After 150,000 km the truck started wandering, etc. I have had three of these trucks earlier years, one lasted me over 400,000 KM so I know about loose sterring this truck is different. On the Hwy, there is a big dead zone in the steering, on corners, it feels a bit over steerie, I have replace everything except the sterring box iteself, any ideas? Is there a sensor for this type of adaptive sterring, if so I have not been able to locate it? Any help would be great I only have 187,000 km on this truck and if I can not fix it I will sell it. But I love this truck.

they are different internally and not interchangeable.

near the booster at the fire wall is the linkage when you changed the booster i'm guessing you hit the rods or knocked it off

Maintenance Requirements - Group 1 • Rotate the tires. See Tire Inspection and Rotation for the proper rotation pattern and additional information. • Inspect the brake system. Check the brake calipers for freedom of movement and lubricate if required. • Inspect the exhaust system and shields. • Lubricate the door hinges, check links, hood and sunroof (if equipped). Maintenance Requirements - Group 2 • Rotate the tires. See Tire Inspection and Rotation for the proper rotation pattern and additional information. • Inspect the brake system. Check the brake calipers for freedom of movement and lubricate if required. • Inspect the exhaust system and shields. • Lubricate the door hinges, check links, hood and sunroof (if equipped). • Inspect the engine accessory drive belt and coolant hoses every 12 months or 18,000 miles (30,000 km), whichever occurs first. Maintenance Requirements - Group 3 • Rotate the tires. See Tire Inspection and Rotation for the proper rotation pattern and additional information. • Inspect the brake system. Check the brake calipers for freedom of movement and lubricate if required. • Inspect the exhaust system and shields. • Lubricate the door hinges, check links, hood and sunroof (if equipped). • Replace the engine air cleaner filter every 36 months or 30,000 mile (50,000 km), whichever occurs first. An Emission Control Service . (See footnote) • Inspect the vacuum lines/hoses every 24 months or 30,000 mile (50,000 km), whichever occurs first. An Emission Control Service . (See footnote) • Replace spark plugs. An Emission Control Service.

this problem is most likely the sterering gear box has a leaking fluid pressure assist valve

YOU WILL NEED TO REMOVE THE STEERING WHEEL YOU REALLY NEED THE CORRECT TOOLS FOR THIS THERE IS A SPRING LOADED COLLAR UNDER THE STEERING WHEEL TO REMOVE THEN YOU WILL SEE THE TURN SIGNAL SWITCH REMOVE THE THREE PHILLIP SCREWS IN SWITCH AND ONE IN EMERGENCY FLASHER BUTTON RAISE UP SWITCH ON RIGHT SIDE YOU WILL SEE AN ALLEN OR TORX SCREW RIGHT AT IGNITION SWITCH REMOVE SCREW AND PULL OUT IGNITION SWITCH

I don't know if this was done. But thought I would ask. Did you get the air out of the lines? if not see if that helped.have a Great day,...

Yea I worked for Ford and have seen this before. Your pump is cavatating. It has air somewhere in the system. Ford pumps are known for being noisy. To get the air out correctly you have to jack the front tires off the ground and while the engine is on turn the steering back and fourth with the cap of the pump. You need to get a small bottle of Fords Friction Modifier and put it in this pump after you get the air out. If your truck has Hydraboost steering then the hydraboost could have a bad seal init allowing the pressure to go backwards through the system. The Hydraboost system is easy to distinguish because it has hoses that go up and attach to the brake booster system. Some trucks came with these and some did not. Hope this helped.

Hydraboost works off of your power steering pump, you will have hoses between them, if it is conventional vacuum then it will have a large round vacuum chamber behind the master cylinder, with one hose running to the engine.

Follow the service intervals recommended in your manual.

• Engine oil and filter every 5,000 km
• Inspect brake system, steering components and wheel hub every 30,000 KM
• Transmission oil and filter, differential and transfer-case service every 80,000 KM
• Service the cooling system every 150,000 KM or 5 years

These are just the common major service intervals to the drive train to keep the car running to the maximum life expectancy, and replace any worn parts that may affect the safe operation of the car. Good luck and keep me posted, be glad to answer any other questions you may have.

It has a hydraboost brake booster right? Sounds like a bad Power steering pump. The belt is still on it right?
