Assumption: This guide covers the front control arms on your Silverado, replacing the worn arms on one side at a time. Fastener access and torque can vary by upper vs lower arm, so follow the step order carefully.

🔧 Control Arms - Front Suspension Replacement

The front control arms locate the wheel and control suspension movement. If the bushings are torn, the ball joints are loose, or the arm is bent, replacement is the correct repair to restore steering feel and tire wear.

Difficulty Level: Advanced | Estimated Time: 4-6 hours

---

⚠️ Safety & Precautions

• Support the truck with jack stands; never work under a vehicle held only by a jack.
• Keep hands clear of the coil spring area. The front suspension stores a lot of force.
• If equipped with an electronic brake cable routed near the work area, avoid pulling or pinching it.
• Use a spring compressor only if the upper arm procedure requires it and you are trained to do so.
• Torque all suspension fasteners at normal ride height when required to prevent bushing preload.
• No battery disconnect is required for this repair.

📋 Before You Begin

• Park on level ground and set the parking brake.
• Loosen the front wheel lug nuts before lifting the truck.
• Raise the front end and support the frame with jack stands.
• Remove the front wheels for access.
• Soak all control arm and ball joint fasteners with penetrating oil before starting.
• Mark cam bolts before removal.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Remove the wheel and free the suspension

• Use a floor jack and jack stands to lift and support the front of the truck.
• Remove the front wheel with a 21mm socket.
• Support the lower control arm lightly with the floor jack so the suspension stays stable.

Step 2: Disconnect the sway bar link and brake line bracket if needed

• Use an 18mm socket or 15mm wrench to remove the sway bar link from the control arm if it blocks access.
• If the brake hose bracket is attached to the arm, remove it with a 10mm socket.
• Move the hose aside carefully; do not let it hang by the line.

Step 3: Separate the ball joint from the steering knuckle

• Remove the cotter pin with needle-nose pliers if present.
• Use a 21mm socket or 24mm socket to remove the ball joint nut.
• Use a ball joint separator or pickle fork to release the stud from the knuckle.
• Leave the nut threaded on a few turns.

Step 4: Remove the upper control arm

• Use a 21mm socket and breaker bar to remove the upper control arm pivot bolts.
• Mark cam bolt positions with a paint marker before removal.
• Remove the arm from the frame.
• Torque on installation: Torque to 140 Nm (103 ft-lbs) for the upper arm pivot fasteners unless your replacement hardware specifies otherwise.

Step 5: Remove the lower control arm

• Support the lower arm with the floor jack.
• Use a 24mm socket and breaker bar to remove the lower control arm pivot bolts.
• If the ball joint is part of the arm, remove the remaining knuckle connection and lower the arm out.
• Torque on installation: Torque to 190 Nm (140 ft-lbs) for the lower arm pivot fasteners unless your hardware kit says otherwise.

Step 6: Install the new control arm(s)

• Position the new arm in the frame using your hands and a pry bar if needed.
• Start all bolts by hand first using the correct 21mm socket or 24mm socket.
• Install the ball joint stud into the steering knuckle.
• Use a 21mm socket or 24mm socket to install the new nut.
• Torque to 81 Nm (60 ft-lbs) on the ball joint nut, then tighten only enough to align the cotter pin hole if required by the hardware.

Step 7: Tighten the pivot bolts at ride height

• Reinstall the wheel with the 21mm socket and lower the truck until the suspension is at normal ride height.
• Use a torque wrench to tighten the control arm pivot bolts at ride height.
• Recheck the upper and lower arm torque values and tighten them to spec.
• Ride-height torque helps the bushings last longer.

Step 8: Reassemble and repeat on the other side if needed

• Reinstall the sway bar link and brake line bracket with the proper sockets.
• Reinstall the wheel and torque the lug nuts with a torque wrench.
• Repeat the same procedure on the other side if replacing both arms in pairs.

✅ After Repair

• Check that all fasteners are fully torqued and cotter pins are installed.
• Test drive slowly at first and listen for clunks or pops.
• Get a professional wheel alignment immediately after this repair.
• Recheck lug nut torque after 25-50 miles.
