Solution

1. Preparation

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

2. Inspect and Replace Worn Components

Inspect CV Joints:
- Remove the front wheel using a socket set.
- Check the CV joint boots for tears and the joint for play. If damaged, proceed to replace.
- Replacement:
  - Use a CV joint puller to remove the old joint.
  - Install the new CV joint, ensuring proper alignment and securing it with the appropriate torque (usually around 30-50 ft-lbs).
Check Suspension Bushings:
- Visually inspect control arm bushings for cracks or excessive wear.
- If damaged, proceed to replace by:
  - Removing the bolts securing the control arm using a torque wrench.
  - Press out the old bushings using a bushing removal tool.
  - Install new bushings and reassemble, torquing to manufacturer specifications.

3. Inspect and Repair Steering Components

Check Steering Rack:
- Inspect the steering rack for leaks or damage.
- If a leak is found, replace the steering rack by:
  - Disconnecting the power steering lines and removing the mounting bolts.
  - Installing the new steering rack and securely tightening it.
  - Refill the power steering fluid and bleed the system.
