Tools Required: Power steering fluid, funnel
Sub-steps:
1. Locate the power steering reservoir and remove the cap.
2. Check the fluid level against the minimum and maximum marks.
3. If the fluid is low or discolored, drain the old fluid using a siphon pump.
4. Replace with manufacturer-recommended power steering fluid and replace the cap.

3. Inspect and Replace Steering Components

Tools Required: Socket set, wrench set, torque wrench
Sub-steps:
1. Lift the front of the vehicle using a jack and secure it on jack stands.
2. Remove the wheel for access to the steering components.
3. Inspect the tie rod ends and control arm bushings for wear; replace if damaged.
4. If necessary, remove the old components and install new ones, using a torque wrench to tighten to manufacturer specifications.

4. Inspect Wheel Bearings

Tools Required: Bearing puller, grease
Sub-steps:
1. Remove the wheel hub assembly if necessary to access the bearings.
2. Check for play in the bearings by moving the hub side to side.
3. If grinding is present, replace the bearings with new ones and pack with grease.

5. Check Brake Components

Tools Required: Brake cleaner, inspection tools
Sub-steps:
1. Inspect brake pads, rotors, and calipers for any debris or damage.
2. Clean the brakes with brake cleaner and check for wear.
