Solution

1. Preparation

Gather tools and parts.
Lift the vehicle using a hydraulic jack and secure it on jack stands.
Remove the front wheels for better access to suspension and steering components.

2. Inspect and Replace CV Joints

Inspect CV Joints:
- Check for torn boots or grease leakage.
- If damaged, remove the affected axle.
Replace CV Joint:
- Use a 10mm socket to remove the bolts securing the CV joint to the wheel hub.
- Use a pry bar to gently pop the joint out of the transmission side.
- Install the new CV joint by reversing the removal steps, ensuring proper torque (usually around 30-40 ft-lbs).

3. Check Suspension Components

Inspect Control Arms and Bushings:
- Look for cracks or excessive play in control arms.
- Replace any worn bushings (use a bushing removal tool).
Replace Worn Components:
- If any parts are excessively worn, replace them using appropriate torque specifications (refer to factory manual for values).

4. Check Steering Rack and Linkage

Inspect Steering Components:
- Look for looseness in the steering rack and tie rod ends.
Replace as Needed:
- If any parts are found to be faulty, replace them, ensuring to torque to manufacturer specifications.
