🔧 1500 - Front Control Arm Replacement

This repair covers replacing the front upper and/or lower control arms on your 1500. Control arms locate the front wheels and contain bushings and ball joints that affect steering, tire wear, braking feel, and alignment.

Difficulty Level: Advanced | Estimated Time: 3-6 hours

Assumption: This procedure is for front control arms. Rear suspension on your 1500 uses a different arm/link setup.

⚠️ Safety & Precautions

• ⚠️ Support your 1500 with jack stands only. Never work under a truck supported by a floor jack alone.
• ⚠️ The front coil spring and strut assembly are under load. Do not loosen the strut center nut.
• ⚠️ Your 1500 has the eTorque mild-hybrid system. This control arm job does not require high-voltage service, but avoid orange high-voltage wiring and components.
• ⚠️ Disconnecting the 12V battery is not normally required for front control arms, but keep the ignition OFF and key away from the truck.
• ⚠️ Always replace control arm fasteners if the new arms include them, and never tighten control arm bushing bolts while the suspension is hanging.
• ⚠️ A wheel alignment is required after replacing control arms.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Loosen the Front Wheel Lug Nuts

• Use a 21mm socket and 1/2-inch drive breaker bar to loosen the front wheel lug nuts about one turn.
• Do not remove the lug nuts yet.
• Break them loose before lifting.

Step 2: Raise and Support the Front of the Truck

• Use a floor jack (rated 3-ton minimum) under the front frame crossmember or approved front jacking point.
• Lift the front of your 1500 high enough to remove the wheels.
• Place jack stands (rated 3-ton minimum) under the frame rails.
• Lower the truck gently onto the jack stands and lightly shake the truck to verify it is stable.

Step 3: Remove the Front Wheel

• Use a 21mm socket to remove the lug nuts.
• Remove the wheel and place it flat under the frame as a backup safety measure.

Step 4: Support the Lower Control Arm

• Place the floor jack (rated 3-ton minimum) under the outer end of the lower control arm.
• Raise the jack slightly until it just supports the arm.
• This keeps the suspension from dropping suddenly when the ball joint is separated.

Step 5: Free the Brake Hose and ABS Wire Brackets

• Use a 10mm socket or trim clip removal tool to detach any brake hose or ABS wire brackets connected near the control arm or knuckle.
• Move the hose and wire gently aside without stretching them.
• ABS means anti-lock brake system. The wire is delicate, so do not pull on it.

Step 6: Disconnect the Sway Bar Link if Needed

• Use an 18mm socket and 18mm wrench to remove the sway bar link nut from the lower control arm if it blocks access.
• A sway bar link connects the suspension arm to the anti-roll bar and helps control body roll.
• Move the link away from the lower control arm.

Step 7: Separate the Upper Ball Joint from the Steering Knuckle

• Use a 21mm socket or 21mm wrench to loosen the upper ball joint nut.
• Leave the nut threaded on a few turns to protect the threads.
• Use a ball joint separator (specialty) to separate the upper ball joint from the steering knuckle.
• A ball joint separator presses the tapered joint apart without hammering directly on the joint.
• Once separated, remove the nut fully with the 21mm socket or 21mm wrench.
• Support the steering knuckle so it does not pull on the brake hose.

Step 8: Remove the Upper Control Arm

• Use a 21mm socket, 21mm wrench, or 18mm socket as fitted to remove the two upper control arm frame bolts.
• Use a paint marker to mark bolt orientation before removal.
• Remove the upper control arm from the truck.
• Compare the old and new upper control arms to confirm the same shape, ball joint angle, and bushing locations.

Step 9: Install the New Upper Control Arm

• Position the new upper control arm in the frame mounts.
• Install the bolts by hand first to avoid cross-threading.
• Use a 21mm socket, 21mm wrench, or 18mm socket to snug the bolts, but do not final-tighten yet.
• Insert the upper ball joint stud into the steering knuckle.
• Use a 21mm socket or 21mm wrench to install the ball joint nut.
• Torque the upper ball joint nut to 40 Nm (30 ft-lbs), then tighten an additional 90 degrees.
• Final torque for upper arm bushing bolts should be done at normal ride height.

Step 10: Separate the Lower Ball Joint from the Steering Knuckle

• Keep the lower control arm supported with the floor jack (rated 3-ton minimum).
• Use a 24mm socket or 24mm wrench to loosen the lower ball joint nut.
• Leave the nut threaded on a few turns.
• Use the ball joint separator (specialty) to separate the lower ball joint from the steering knuckle.
• Remove the nut fully with the 24mm socket or 24mm wrench.
• Carefully support the steering knuckle so the brake hose is not stretched.

Step 11: Mark and Remove the Lower Control Arm Cam Bolts

• Use a paint marker to mark the exact position of each cam washer on the frame.
• Use a 24mm socket and 24mm wrench to loosen and remove the lower control arm mounting bolts.
• Use a dead blow hammer and pry bar set only if the bolts are stuck.
• Remove the lower control arm from the truck.
• Paint marks get you close, not aligned.

Step 12: Install the New Lower Control Arm

• Position the new lower control arm into the frame pockets.
• Install the cam bolts and washers in the same direction they came out.
• Use the paint marker marks to place the cam washers close to their original positions.
• Use a 24mm socket and 24mm wrench to snug the lower control arm bolts, but do not final-tighten yet.
• Guide the lower ball joint stud into the steering knuckle.
• Use a 24mm socket or 24mm wrench to install the lower ball joint nut.
• Torque the lower ball joint nut to 70 Nm (52 ft-lbs), then tighten an additional 90 degrees.

Step 13: Reconnect the Sway Bar Link and Brackets

• Use an 18mm socket and 18mm wrench to reconnect the sway bar link to the lower control arm.
• Torque the sway bar link nut to 100 Nm (74 ft-lbs).
• Use a 10mm socket or trim clip removal tool to reinstall brake hose and ABS wire brackets.
• Make sure the brake hose and ABS wire do not rub the tire, spring, or control arm.

Step 14: Set the Suspension to Ride Height Before Final Tightening

• Use a tape measure to measure from the center of the wheel hub to the fender lip on the opposite front side before lifting, if available.
• Use the floor jack (rated 3-ton minimum) under the lower control arm to raise the suspension to normal ride height.
• Ride height means the position the suspension sits at when the truck is on the ground.
• This prevents twisting and damaging the new rubber bushings.

Step 15: Final-Tighten the Control Arm Mounting Bolts

• Use a 21mm socket and 21mm wrench to tighten the upper control arm frame bolts.
• Torque the upper control arm frame bolts to 115 Nm (85 ft-lbs).
• Use a 24mm socket, 24mm wrench, and 1/2-inch drive torque wrench to tighten the lower control arm cam bolts.
• Torque the lower control arm cam bolts to 203 Nm (150 ft-lbs).
• Keep the cam washers aligned with your paint marks while tightening.

Step 16: Reinstall the Wheel

• Place the wheel back on the hub.
• Use a 21mm socket to install the lug nuts by hand.
• Snug the lug nuts in a star pattern with the 21mm socket.

Step 17: Lower the Truck and Torque the Lug Nuts

• Use the floor jack (rated 3-ton minimum) to lift the truck slightly off the jack stands.
• Remove the jack stands (rated 3-ton minimum).
• Lower the truck to the ground.
• Use a 21mm socket and 1/2-inch drive torque wrench to tighten the lug nuts in a star pattern.
• Torque the wheel lug nuts to 176 Nm (130 ft-lbs).

Step 18: Repeat on the Other Side if Replacing in Pairs

• Use the same tools and steps on the opposite side.
• Control arms can be replaced one side at a time, but worn suspension parts are often best replaced in pairs.

✅ After Repair

• ✅ Turn the steering wheel slowly from lock to lock and check for hose or wire stretching.
• ✅ Test drive slowly at first. Listen for clunks, rubbing, or steering pull.
• ✅ Schedule a professional four-wheel alignment immediately. Your 1500 will not hold proper tire wear without it.
• ✅ After 50-100 miles, recheck lug nut torque with a 21mm socket and 1/2-inch drive torque wrench.
• ✅ If the steering wheel is off-center, do not keep driving long distances before alignment.
