Power steering worm gear sector type (BMW 7 Series E32)

Filling the power steering system with fluid and bleeding air

With the engine not running, fill the reservoir to 25 mm below the edge.

Start the engine and top up the reservoir. Remove air from the system by rotating the steering wheel from one extreme position to the other. Top up the reservoir as you go. Press the brake pedal five times, wait 30 seconds, and press the pedal five more times.

Check the fluid level with the engine off. Press the brake pedal until the accumulator is empty. The accumulator is empty if the oil level in the reservoir no longer increases or if the force applied to the pedal drops sharply.

Models without ground clearance control

The fluid level should be 10 mm below the top edge of the tank.

Models with adjustable ground clearance

Raise the rear axle so that the wheels hang freely. After two minutes, the fluid level should be a maximum of 5 mm above the bottom of the grid.



If the level is low, top up with the engine not running.

Steering adjustment

When performing this work, the steering gear and steering column bearing/joint must be in perfect condition. Disconnect the steering rod from the steering arm.





Unscrew the nut and push out the ball joint with a puller.

Set the steering wheel to the middle position. Take into account the marks on the shaft and the steering gear housing.



Remove the BMW emblem from the steering wheel and remove the airbag assembly.

Install the torque amplifier meter on the steering wheel.



Turn the steering wheel to the left one turn.



Turn the steering wheel to the right at the pressure position, read the instrument readings. The increase in resistance force should be 1.4 Nm.

Adjustment

Loosen the castle nut on the steering gear, set the screw (2) to a position where the increase in turning resistance is normal.
