Replacing a steering control arm can be a complex task that requires some mechanical experience and knowledge. Here are the general steps involved in replacing the steering control arm:

First, you need to lift the vehicle and secure it on jack stands. Make sure that the vehicle is supported securely before working on it.

Remove the front wheels on both sides of the vehicle.

Locate the steering control arm on the side of the vehicle that you want to replace. The steering control arm is connected to the steering knuckle and the steering gearbox.

Remove the bolts that attach the steering control arm to the steering knuckle and the steering gearbox. You may need to use a breaker bar or impact wrench to remove these bolts.

Once the bolts are removed, you can remove the old steering control arm from the vehicle.

Install the new steering control arm by attaching it to the steering knuckle and the steering gearbox using the bolts that you removed earlier.

Tighten the bolts to the recommended torque settings.

Reinstall the front wheels and lower the vehicle off the jack stands.

Finally, you will need to perform an alignment to ensure that the new steering control arm is properly adjusted.

It's important to note that the above steps are general guidelines and the specific steps for replacing a steering control arm may vary depending on the make and model of your vehicle. If you are not confident in your ability to replace the steering control arm, it's best to seek the assistance of a qualified mechanic.
