Solution

1. Preparation

Tools Required: Socket set, torque wrench, fluid catch pan, power steering fluid, shop towels.
Ensure the vehicle is parked on a flat surface and turn off the engine.
Disconnect the negative battery terminal to avoid electrical issues.

2. Drain Power Steering Fluid

Place a fluid catch pan under the power steering fluid reservoir.
Remove the cap and use a siphon pump to drain the fluid from the reservoir into the pan.
Dispose of the old fluid according to local regulations.

3. Remove the Steering Rack

Tools Required: Wrench set, socket set.
Lift the front of the vehicle using a jack and secure with jack stands.
Disconnect the steering column from the rack by removing the bolts and sliding it off.
Detach the tie rods from the steering rack using a tie rod puller.
Remove the bolts securing the steering rack to the subframe and carefully slide it out.

4. Inspect and Replace Seals

Examine the steering rack for worn or damaged seals.
If leaks are found, use a seal kit designed for the Mustang S550.
Remove the old seals using a seal puller and replace them with new ones from the kit.

5. Reinstall the Steering Rack

Position the steering rack back into place and secure it with bolts to the subframe. Torque bolts to manufacturer specifications (usually around 40-50 lb-ft).
Reconnect the tie rods and steering column, ensuring all connections are tight.
Refill the power steering fluid reservoir with new fluid.

6. Bleed the Power Steering System

Start the engine and turn the steering wheel from lock to lock several times to bleed air out of the system.
Check the fluid level and add more if necessary.
