Solution

1. Preparation

Gather necessary tools and parts.
Elevate the vehicle using a jack and secure it on jack stands.
Disconnect the battery (negative terminal) to ensure safety.

2. Inspect and Replace Worn Components

Sub-step 1: Check CV Axles
- If CV joints are damaged, remove the axle:
  - Use a socket set to remove the axle nut.
  - Disconnect any brackets holding the axle in place.
  - Slide the axle out of the hub.
- Replace with a new CV axle if damaged.
Sub-step 2: Replace Control Arm Bushings
- If bushings are worn, remove the control arm:
  - Use a socket set to remove the bolts securing the control arm to the chassis and wheel hub.
  - Replace the bushings in the control arm using a press or bushing tool.
  - Reinstall the control arm with new bushings.
Sub-step 3: Replace Ball Joints
- If ball joints are faulty, remove and replace them:
  - Use a ball joint separator to detach the ball joint from the control arm and steering knuckle.
  - Install a new ball joint using a press.

3. Reassemble and Torque Components

Reinstall any removed components, ensuring all bolts are torqued to manufacturer specifications (typically 50-70 lb-ft for control arms, check specific values for your vehicle).
Reconnect the battery.
