Replacing a control arm in a 2002 Volkswagen Jetta involves the following steps:

Note: This guide provides general instructions, but the exact process may vary slightly depending on your specific model and trim level. It is recommended to refer to a repair manual or consult a professional mechanic if you are unsure about any steps.

Tools and Materials Needed:

- Basic hand tools (wrenches, sockets, screwdrivers)

- Jack and jack stands

- Replacement control arm

- New bolts and nuts

- Loctite or threadlocker

- Spray lubricant

- Safety glasses

Instructions:

1. Preparation:

- Ensure that the vehicle is parked on a level surface, and the parking brake is engaged.

- Loosen the lug nuts of the wheel on the side where the control arm needs to be replaced, but do not remove them completely.

2. Raise the Vehicle:

- Place the jack under the appropriate lifting point on the vehicle. Consult the owner's manual for specific lifting points.

- Raise the vehicle until the tire where you loosened the lug nuts is about 6 inches off the ground.

- Secure the vehicle with jack stands to ensure it remains safely in place.

3. Remove the Wheel and Fender Liner:

- Remove the lug nuts completely and take off the wheel.

- If there is a plastic fender liner covering the control arm area, remove the necessary screws or fasteners to expose the control arm.

4. Disconnect the Stabilizer Link:

- Locate the stabilizer link that connects to the control arm.

- Use an appropriate wrench or socket to loosen and remove the nut securing the stabilizer link to the control arm.

- Disconnect the stabilizer link from the control arm.

5. Disengage the Ball Joint:

- Locate the ball joint where the control arm connects to the steering knuckle.

- Remove the cotter pin from the ball joint nut.

- Loosen the ball joint nut until the pressure is released and it comes off easily.

- Use a ball joint separator tool or a pry bar to separate the ball joint from the steering knuckle.

6. Remove the Control Arm Mounting Bolts:

- There are typically two or more bolts that secure the control arm to the vehicle's subframe or chassis.

- Locate these bolts and use the appropriate wrenches or sockets to loosen and remove them.

7. Remove the Old Control Arm:

- Once all mounting bolts are removed, carefully remove the old control arm from the vehicle.

- Note the position and orientation of the old control arm for reference when installing the new one.

8. Install the New Control Arm:

- Place the new control arm into position, ensuring that the mounting points align properly.

- Insert the mounting bolts and temporarily hand-tighten them.

- Reattach the ball joint by inserting it into the steering knuckle and securing it with the ball joint nut and a new cotter pin.

9. Secure the Control Arm Mounting Bolts:

- Tighten the control arm mounting bolts to the specified torque according to the vehicle's repair manual.

- Secure the bolts with threadlocker or Loctite to prevent them from loosening.

10. Reconnect the Stabilizer Link:

- Reattach the stabilizer link to the control arm and secure the nut accordingly.

11. Reinstall the Wheel and Fender Liner:

- If applicable, reinstall the fender liner.

- Reinstall the wheel and lug nuts, but do not tighten them fully at this point.

12. Lower the Vehicle:

- Slowly lower the vehicle using the jack.

13. Tighten the Lug Nuts and Check Stability:

- Fully tighten the lug nuts once the vehicle is back on the ground.

- Lightly shake and move the vehicle to ensure that the control arm is properly secured.

Note: It's important to align the vehicle after replacing the control arm to ensure proper handling and tire wear. It is recommended to have a professional alignment done to ensure the correct specifications are met.
