Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety while working on electrical components if necessary.

2. Inspect and Replace Power Steering Fluid

Remove the power steering fluid reservoir cap.
Check the fluid condition; if dirty, drain and replace with OEM-spec fluid.
Refill to the recommended level and replace the cap.

3. Replace Damaged CV Joints (if applicable)

Raise the front of the vehicle using a jack and secure with jack stands.
Remove the wheel and tire assembly.
Unbolt the axle nut and disconnect the CV joint from the hub.
Remove any retaining clips and pull the CV axle out of the transmission.
Install the new CV joint or axle by reversing the removal procedure. Tighten the axle nut to manufacturer specifications (typically around 30-45 Nm, consult the service manual for exact figures).

4. Replace or Lubricate Wheel Bearings (if applicable)

Remove the wheel and tire assembly as in the previous step.
If the wheel bearing is damaged, remove the brake caliper and rotor.
Unbolt and remove the hub assembly.
Replace the wheel bearing using a bearing press or suitable tool.
Reassemble components and torque bolts to manufacturer specifications.

5. Inspect and Replace Suspension Components (if necessary)

Check control arms, bushings, and tie rods for wear.
Replace any damaged components using appropriate tools (socket set, wrenches).
Ensure all bolts are torqued to specification.
