Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery if working on electrical components.

2. Inspect and Replace Power Steering Fluid

Tools Required: Funnel, power steering fluid
- Check the power steering fluid level using the dipstick.
- If low, add the appropriate power steering fluid as specified in the owner's manual.
- If the fluid is dirty or contaminated, perform a fluid flush.

3. Inspect and Replace CV Joints

Tools Required: Jack, jack stands, socket set
- Raise the front of the vehicle and secure it with jack stands.
- Remove the front wheels.
- Inspect the CV joints and boots for cracks or leaks.
- If damaged, replace the CV joint assembly:
  1. Remove the axle nut with a socket wrench.
  2. Disconnect the lower control arm from the steering knuckle.
  3. Remove the old CV joint by pulling it out of the transmission.
  4. Install the new CV joint by reversing the removal steps and ensure proper torque on the axle nut (typically 150-175 ft-lbs).

4. Inspect Suspension Components

Tools Required: Wrench set, torque wrench
- Check all control arms, struts, and bushings for wear or damage.
- Replace any worn or damaged components:
  1. Remove the affected component using the socket set.
  2. Install the new component, ensuring all bolts are torqued to manufacturer specifications.

5. Test Steering Linkage
