How to Replace Control Arm 99-09 Volkswagen Jetta

Difficulty: Advanced · About 90 min · Volkswagen Jetta

Replace a front lower control arm on a 1999–2009 Volkswagen Jetta, transferring the bolt-on ball joint, supporting the steering knuckle, and checking alignment after suspension fasteners are tightened.

Steps

1. Raise the vehicle and remove the wheel

   Loosen the lug nuts on the ground, raise the front, and support it securely on a jack stand. Remove the wheel and set it aside.

2. Disconnect the control arm

   Remove the front and rear control arm fasteners while supporting the arm. Disconnect the sway bar link and separate the ball joint from the steering knuckle, keeping the knuckle supported so it does not pull on the axle or brake hose.

3. Transfer the ball joint

   Remove the ball joint bracket bolts and inspect the joint boot and stud for damage or looseness. Transfer a serviceable joint to the replacement arm in the same orientation, tightening its bolts to the vehicle specification.

4. Install the replacement arm

   Guide the new arm into its mounting points and start all fasteners by hand. Reconnect the ball joint to the knuckle and reinstall the sway bar link without forcing the threads.

5. Tighten suspension fasteners

   Tighten the control arm, ball joint, and sway bar fasteners to the manufacturer's specifications. Where the service procedure requires bonded bushings to be tightened at ride height, support the suspension at normal operating position first.

6. Reinstall the wheel

   Reinstall the wheel and tighten its fasteners in a star pattern to the vehicle specification. Lower the vehicle and verify that no hose, wire, or boot is twisted or contacting the tire.

7. Check alignment and suspension

   Have the front wheel alignment checked because control arm replacement can change suspension geometry. Listen for abnormal noises and verify steering behavior during a cautious road test.

Check your vehicle’s repair manual for exact specifications and fit.
