Step 2: Safely Elevate Your Vehicle

Park your Yukon on a flat surface. Use the hydraulic jack to lift the front of your vehicle, then place the jack stands under it to ensure it stays elevated safely.

Step 3: Remove the Old Control Arm

Locate the upper control arm and remove the nuts holding the arm to the frame and the spindle using your socket set and wrench. Be cautious not to damage the spindle or brake lines. Use the pry bar if necessary. Once the nuts and bolts are removed, you can take out the old control arm.

Step 4: Install the New Control Arm

Take your new upper control arm and position it in the mounting bracket. Attach it to the frame and spindle using the new bolts and nuts provided. Make sure to tighten them securely using your socket and wrench set.

Step 5: Lower the Vehicle

Once everything is securely in place, you can safely lower your vehicle off the jack stands using the hydraulic jack.

Common Challenges and Potential Mistakes

The process of replacing the upper control arm may seem straightforward, but it does come with its challenges. Common issues include difficulty in removing rusted or stuck bolts and incorrect alignment during the new control arm installation. Always soak rusted components in a rust dissolver and make sure to align everything properly before tightening.

Another common mistake is not using the correct tools or not securing the vehicle safely before starting the process. Always use the recommended tools and ensure your vehicle is safely elevated and stabilized on jack stands.

Conclusion: Professional Assistance May Be Needed
