How to fix power steering?

Does kind of buzz at an idle and it whine when you try to turn? You could be low on power steering fluid. Sometimes people put the wrong fluid un it pump instead of power steering fluid which will cause problem because the fluid is too thick.
You could possibly have a pump going out on you.
Jack the car up to get the front wheels off the ground. With the engine off, turn the steering wheel lock to lock. If you feel any binding as you turn you may have a bent steering rack.

Do you have electic power steering?

If fluid is clear , light brown , try red auto trans fluid , unhook lowest fluid line to drain system .

Google the question-Plenty to read

There are several tools for that

When you buy a brand new 5.4 3 valve,
you bring it home & remove the 2 piece
plugs & install the one piece Champion 7989

Now your years down the road & have a problem

Changed the oxygen sensors at 100,000 miles?

Trans & Power Steering Fluid on all your vehicles
every 3 years- brake fluid every 2 years

Spark Plugs get Changed every 3 years

check power steering fluid level, and belt condition & tension, may need replaced or tightened.

Check the power steering fluid levels. Also the pump may need replacing if it isn't delivering enough hydraulic pressure to the steering box. Be sure to lube all the steering components on the chassis if possible.

fluid level ok? then a bad pump you have

Hi, this really depends on its service history.

The following are the recommended service intervals on the Merc S500:

Note: operate A/C at least once per week, to maintain lubrication.

Underhood & Undervehicle

Every 3,000 miles - Replace engine oil & oil filter. Clean battery terminals. Adjust drive belt. Check power steering fluid. Check steering & CV BOOTS for wear and replace if necessary. Lubricate front end suspension.

Every 6,000 miles - Check transmission fluid condition and level. Check brake pads and caliper components - replace if necessary. Lubricate driveshaft U-joints. Rotate tires. Lubricate wiper arm linkage and pivots.

Every 12,000 miles - Adjust engine valve clearance. Replace distributor cap & rotor. Drain and replace engine Coolant. Replace Air Filter element. Replace Fuel Filter. Replace wiper blades.

Every 24,000 miles - Replace Drive Belt. Replace A/C Compressor Drive Belt. ** Change auto transmission fluid & trans filter (this is critical and must be adhered to) - preferrably do a trans flush at same time. Replace drive AXLE fluid.

Every 36,000 miles - Replace HT leads.

Every 2 years - Replace brake fluid (also clutch fluid if applicable). Replace power steering fluid.


** If you intend to keep this vehicle long term, then consider changing the trans fluid & filter every 20,000 miles. This is the secret to automatic transmission longevity.

1. Disconnect and isolate the negative battery cable.
   
2. Remove the accessory drive belt. The belt does not have to be removed from the engine.
   
3. Raise and safely support the vehicle.
   
4. Disconnect the wiring harness connector to the oxygen sensor which is accessible through the oxygen sensor wiring harness grommet in the vehicle floor pan.
   
5. Remove the catalytic converter from the exhaust manifold and remove all exhaust system hangers and isolators from the exhaust system brackets. Move exhaust system out of the way as far rearward and to the left as possible to provide access to the power steering pump.
   
6. Place a drain pan under the power steering pump. Remove the power steering fluid return line hose on the front suspension cradle. Allow the fluid to drain from the pump and hose.
   
7. Remove the accessory drive belt splash shield.
   
8. Disconnect the power steering remote reservoir supply hose from the fitting on the power steering pump. Allow fluid to drain from the hose.
   
9. Remove power steering fluid pressure line from the power steering pump and drain any excess power steering fluid.
   
10. Remove the power steering fluid return hose from the power steering pump.
    
11. Remove the rear support bracket mounted behind the power steering pump to the engine block.
    
12. Remove the 2 mounting bolts that secure the pump to the alternator/power steering pump and belt tensioner mounting bracket.
    
13. Remove the power steering pump and pulley assembly out from the vehicle. Transfer all required parts from the pump to the new replacement pump before installation.
    

To install:

1. Position the front of the power steering pump up onto the mounting bracket. Torque the 2 power steering pump-to-mounting bracket bolts to 40 ft. lbs. (54 Nm).
   
2. Install the rear power steering pump-to-engine block support bracket. Torque the 2 support bracket mounting bolts to 40ft. lbs. (54 Nm). Install the nut to the mounting stud behind the pump and torque to 40 ft. lbs. (54 Nm).
   
3. Install the high pressure fluid line to the pump output fitting. Torque the high pressure line-to-power steering pump fitting to 275 inch lbs. (31 Nm). Be sure to inspect the pressure line O-ring for any damage before connecting the pressure line to the steering pump.
   
4. Install the low pressure power steering fluid hose to the power steering pump low pressure fitting. Be sure the hose clamps are properly reinstalled and hoses are clear of the accessory drive belts.
   
5. Install the accessory drive belt.
   
6. Install the hose on the power steering fluid return line on the front suspension cradle. Be sure the hose clamps and heat shield tubes are correctly reinstalled.
   
7. Reconnect the exhaust pipe to the exhaust manifold. Install the hangers and isolators onto the exhaust system brackets. torque the nuts and bolts to 250 inch lbs. (28 Nm).
   
8. Reconnect the wiring harness connectors to the oxygen sensor. Install the wiring harness grommet into the vehicle floor pan.
   
9. Install the accessory drive belt splash shield.
   
10. Remove the drain pan and lower the vehicle.
    
11. Refill the power steering pump reservoir with the correct amount of clean power steering fluid.
    
12. Reconnect the negative battery cable. Bleed the power steering system.
    
13. Run the engine and check the system for leaks and proper steering operation.
