6. Reconnect the negative battery terminal.

3. Inspect and Replace CV Joints/Axles

Tools Required: Socket set, torque wrench, CV joint puller (if needed)
Steps:
1. Lift the vehicle using jack stands and remove the front wheels.
2. Inspect the CV boots for tears; if damaged, replace the entire CV joint or axle.
3. Remove the axle nut using a socket and impact wrench if necessary.
4. Disconnect the axle from the hub and transmission, using a CV joint puller if required.
5. Install the new axle by reversing the removal steps and torque the axle nut to specifications.

4. Inspect and Replace Suspension Components

Tools Required: Socket set, torque wrench, pry bar
Steps:
1. Lift the vehicle and securely support it on jack stands.
