Disconnect the battery to prevent electrical issues.

2. Inspect and Replace Steering Components

Tools Required: Socket set, torque wrench, jack stands, steering wheel puller (if necessary).
Inspect the steering rack and tie rod ends for wear.
If damaged, replace the steering rack:
1. Lift the front of the vehicle using a jack and secure it with jack stands.
2. Remove the front wheels to access the steering components.
3. Disconnect the tie rods from the steering rack using a socket set.
4. Remove any mounting bolts securing the steering rack to the subframe.
5. Carefully remove the steering rack from the vehicle.
6. Install the new steering rack in the reverse order, ensuring all bolts are torqued to manufacturer specifications.

3. Check and Top Off Power Steering Fluid

Inspect the power steering fluid reservoir for leaks.
If fluid is low, top off with the correct type of power steering fluid as specified in the owner’s manual.

4. Wheel Alignment

After any steering component replacement, perform a wheel alignment.
1. Use a professional alignment machine to measure and adjust alignment settings.
2. Ensure that camber, caster, and toe are set to factory specifications.
