Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.

2. Inspect and Replace Power Steering Fluid

Tools Required: Funnel, clean rags
Check the power steering fluid reservoir for low fluid levels.
If fluid is low, top it off with the manufacturer-recommended power steering fluid.
If fluid is dirty or contaminated, drain the old fluid and replace it with new fluid.

3. Inspect and Replace CV Joints

Tools Required: Jack, jack stands, socket set, torque wrench
Raise the front of the vehicle and secure it on jack stands.
Remove the wheel and inspect the CV joint for cracks or tears in the boot.
If damaged, remove the axle nut and disconnect the CV joint from the hub.
Replace the CV joint with a new one and reassemble, ensuring proper torque specifications are followed.

4. Check and Replace Steering Rack if Necessary

Tools Required: Socket set, torque wrench
Inspect the steering rack for leaks or damage.
If the steering rack is faulty, disconnect the steering column from the rack.
Remove the mounting bolts and take out the old steering rack.
Install the new steering rack, reconnect the steering column, and torque all bolts to manufacturer specifications.

5. Inspect and Replace Suspension Components

Tools Required: Socket set, torque wrench
Inspect control arms, bushings, and other suspension components for wear.
If any components are found to be damaged, remove them using appropriate tools.
Replace with new parts, ensuring all fasteners are torqued to the specified values.
