A. Suspension Inspection

Use a jack to lift the front of the vehicle and secure it with jack stands.
Inspect the lower control arms and ball joints for wear or damage.
- Torque specifications: If replacing, refer to manufacturer specifications for torque values when reassembling.
Use a pry bar to check for play in the ball joints.

B. CV Joint Inspection

Examine the CV joint boots for tears or grease leakage.
If damaged, remove the affected CV joint:
- Steps:
  - Remove the wheel.
  - Disconnect the lower control arm from the knuckle.
  - Detach the axle from the transmission.
Replace the CV joint or axle if necessary, ensuring to use new grease and secure the boot properly.
