TRW JTC347 Track Control Arm

Installing the TRW JTC347 Track Control Arm is a straightforward process that can be completed with basic hand tools. Below is a general guide for technicians and enthusiasts:

1. Preparation: Raise the vehicle using a jack and secure it on jack stands. Remove the wheel to access the suspension components.
2. Remove Old Arm: Loosen the mounting bolts that attach the existing control arm to the steering knuckle and chassis. Carefully detach the arm, noting any alignment marks or reference points.
3. Position New Arm: Align the JTC347 with the mounting holes on both the steering knuckle and the chassis. Ensure that the bushings are seated correctly and that the arm’s orientation matches the original geometry.
4. Tighten Bolts: Secure the bolts to the specified torque settings (typically found in the vehicle’s service manual). Use a calibrated torque wrench for accuracy.
5. Reassemble Wheel: Reinstall the wheel, lower the vehicle, and perform a test drive to verify proper alignment and handling.
