Locate the power steering reservoir.
Remove the cap and check the fluid level; refill if necessary with the appropriate power steering fluid.
Inspect for any signs of contamination or burnt smell in the fluid.

Raise the front of the vehicle using a jack and secure it on jack stands.
Visually inspect the steering linkage, including the tie rods and ball joints, for any signs of wear or play.
Replace any worn or damaged components using a socket set and torque to manufacturer specifications.

4. Examine Front Suspension Components

Inspect the control arms, bushings, and strut assemblies for damage.
If any components are damaged, replace them accordingly. Use a torque wrench to install new parts to the specified torque values.

5. Test Steering Rack

If issues persist, detach the steering rack from the vehicle.
Check for internal wear or damage by moving the rack manually. If it feels rough, replace the steering rack.
Reinstall the steering rack and ensure proper alignment.
