Solution

1. Preparation

Tools Required: Socket set, torque wrench, jack stands, pry bar, flashlight
Lift the front of the vehicle using a jack and secure it with jack stands.
Ensure the vehicle is on a level surface to prevent accidents.

2. Inspect and Replace Suspension Components

Inspect Control Arms:
- Remove the wheel for easier access.
- Use a pry bar to check for play in the control arm bushings.
- If worn, replace the control arm with a new one.
Replace Struts:
- If the struts are leaking or damaged, remove the strut assembly by unbolting it from the upper strut mount and lower control arm.
- Install new struts, ensuring to torque bolts to factory specifications (typically 40-50 ft-lbs).

3. Examine and Replace CV Joints

Inspect CV Joints:
- Check the outer CV joint for torn boots or excessive grease leakage.
- If damaged, remove the axle by unbolting the hub assembly and pulling the axle out.
- Replace with a new axle assembly if necessary.

4. Check and Tighten Steering Components

Inspect Steering Rack:
- Check the steering rack mounting points for tightness.
- If loose, tighten the bolts to the specified torque (usually around 37-44 ft-lbs).

5. Final Assembly and Wheel Alignment

Reinstall the wheels and lower the vehicle to the ground.
Ensure all bolts are tightened to specifications.
Perform a wheel alignment to prevent uneven tire wear.
