This tutorial provides a step-by-step guide on how to replace the front control arm in a 2007-2012 Nissan Sentra. Control arms are essential components of your vehicle's suspension system, responsible for maintaining alignment and supporting the vehicle's load. Over time, these parts can wear out, necessitating replacement. Follow these instructions to safely and effectively install a new control arm.

Step 1: Gather Necessary Tools and Materials

Before starting the replacement process, ensure you have all the required tools and materials:

  • 21mm Socket
  • 32mm Socket
  • Pickle Fork
  • Straight Cutters
  • 3/8 Inch Impact Gun
  • Socket Driver
  • Swivel
  • Torque Wrench (recommended torque of 125 ft-lbs)
  • Liquid Thread Locker
  • Rust Penetrant
  • Center Punch
  • Floor Jack
  • Hammer
  • Jack Stands
  • Wire Brush

Step 2: Prepare Your Vehicle

  1. Safety First: Park your vehicle on a flat, stable surface and engage the parking brake.
  2. Lift the Vehicle: Use a floor jack to lift the front of the vehicle and secure it with jack stands.
  3. Remove the Front Wheel: Take off the wheel on the side where you will be replacing the control arm.

Step 3: Remove the Old Control Arm

  1. Apply Rust Penetrant: Spray rust penetrant on the bolts and nuts securing the control arm to help loosen them.
  2. Detach the Control Arm
    • Use a 21mm socket to remove the bolts connecting the control arm to the chassis.
    • If necessary, use a pickle fork to separate the ball joint from the steering knuckle.
  3. Remove Additional Components: If any other components are obstructing access, remove them carefully.

Step 4: Clean the Area

  • Use a wire brush to clean any rust or debris from the area where the control arm attaches. This ensures a secure fit for the new control arm.

Step 5: Install the New Control Arm

  1. Position the New Control Arm: Align it in place, making sure it fits snugly against the chassis and steering knuckle.
  2. Secure the Control Arm
    • Insert and hand-tighten the bolts.
    • Use a torque wrench to tighten bolts to the specified torque of 125 ft-lbs.
  3. Apply Liquid Thread Locker: For added security, apply liquid thread locker to the bolts before fully tightening them.

Step 6: Reassemble and Lower the Vehicle

  1. Reattach Any Removed Components: Ensure everything that was taken off is securely reinstalled.
  2. Reinstall the Front Wheel: Place the wheel back onto the hub and hand-tighten the lug nuts.
  3. Lower the Vehicle: Carefully remove the jack stands and lower the vehicle with the floor jack.

Step 7: Final Checks

  • Once the vehicle is on the ground, use the torque wrench to ensure all lug nuts are tightened to the manufacturer's specifications.
  • Test drive the vehicle to ensure the new control arm is functioning properly and there are no unusual noises or handling issues.

Conclusion

Replacing the front control arm on a 2007-2012 Nissan Sentra is a straightforward process that can improve your vehicle's handling and alignment. Ensure you follow each step carefully and double-check your work for safety. If you encounter any issues, consider consulting a professional mechanic for assistance.
