🔧 Tacoma - Front Control Arm Replacement

This repair covers replacing the front control arms on your Tacoma. Control arms locate the front wheels and connect the suspension to the frame; worn bushings or ball joints can cause clunks, loose steering, pulling, or uneven tire wear.

Difficulty Level: Advanced | Estimated Time: 4-7 hours

Assumption: This guide covers front upper and lower control arms. If replacing only one arm, follow the matching steps and skip the rest.

⚠️ Safety & Precautions

• ⚠️ Use jack stands under the frame. Never rely on a floor jack alone.
• ⚠️ The front coil spring is under heavy tension. Do not remove the center nut on the shock/coil assembly.
• ⚠️ Support the lower control arm with a jack before disconnecting suspension parts.
• ⚠️ Keep the steering knuckle supported so it does not stretch the brake hose or ABS wire.
• ⚠️ Final tightening of control arm bushing bolts must be done at normal ride height to prevent bushing damage.
• ⚠️ A wheel alignment is required after this repair.
• ⚠️ Battery disconnect is not required.

📋 Before You Begin

• Park your Tacoma on level ground.
• Set the parking brake and place wheel chocks behind the rear tires.
• Use a 21mm socket to loosen the front lug nuts one turn before lifting.
• Spray penetrating oil on the control arm bolts, ball joint nuts, sway bar link nuts, and lower shock bolt.
• Use a paint marker to mark the lower control arm alignment cam washers. These marks help you drive to the alignment shop, but they do not replace an alignment.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Lift and Secure the Front End

• Use a 21mm socket and breaker bar to loosen the front lug nuts one turn.
• Use a floor jack under the front frame crossmember to lift the front of your Tacoma.
• Place jack stands under the frame rails.
• Lower the vehicle gently onto the jack stands.
• Use a 21mm socket to remove the lug nuts and front wheels.
• Shake gently to confirm stability.

Step 2: Support the Lower Control Arm

• Place the floor jack under the outer end of the lower control arm.
• Raise the jack until it just supports the arm.
• This prevents the suspension from dropping suddenly.

Step 3: Remove the Skid Plate if Equipped

• Use a 12mm socket or 14mm socket to remove the skid plate bolts if it blocks access.
• Lower the skid plate by hand and set it aside.

Step 4: Disconnect the Sway Bar Link

• Use a 17mm socket and 17mm wrench to remove the sway bar link nut at the lower control arm.
• If the stud spins, hold the stud while turning the nut with the 17mm wrench.
• Move the sway bar link away from the lower control arm.
• On reassembly, tighten the sway bar link nut to Torque to 70 Nm (52 ft-lbs).

Step 5: Remove the Lower Shock Bolt

• Use a 19mm socket and 19mm wrench to remove the lower shock bolt and nut from the lower control arm.
• Leave the upper shock mount attached.
• On reassembly, tighten the lower shock bolt to Torque to 100 Nm (74 ft-lbs).

Step 6: Disconnect the Upper Ball Joint

• Use needle-nose pliers to remove the cotter pin from the upper ball joint nut.
• A cotter pin is a small bent pin that locks a nut in place.
• Use a 19mm socket to loosen the upper ball joint castle nut a few turns, but leave it on the stud.
• A castle nut has slots on top for the cotter pin.
• Use a ball joint separator to pop the upper ball joint loose from the steering knuckle.
• A ball joint separator safely separates the tapered joint without hammering on the knuckle.
• Remove the nut fully with the 19mm socket.
• Use a bungee cord to support the steering knuckle.
• On reassembly, tighten the upper ball joint nut to Torque to 110 Nm (81 ft-lbs), then install a new cotter pin.

Step 7: Remove the Upper Control Arm

• Use a 19mm socket and 19mm wrench to remove the long upper control arm pivot bolt and nut.
• Pull the upper control arm out of the frame brackets.
• Install the new upper control arm into the brackets by hand.
• Slide the pivot bolt through the frame brackets and control arm bushings.
• Thread the nut on by hand, but do not fully tighten yet.
• Final upper control arm pivot bolt torque is Torque to 135 Nm (100 ft-lbs).

Step 8: Disconnect the Lower Ball Joint

• Use needle-nose pliers to remove the cotter pin from the lower ball joint nut.
• Use a 24mm socket to loosen the lower ball joint nut a few turns.
• Use a ball joint separator to separate the lower ball joint from the steering knuckle.
• Remove the lower ball joint nut fully with the 24mm socket.
• Keep the steering knuckle supported with a bungee cord.
• On reassembly, tighten the lower ball joint nut to Torque to 160 Nm (118 ft-lbs), then install a new cotter pin.

Step 9: Mark the Lower Control Arm Cam Bolts

• Use a paint marker to mark each lower control arm cam washer against the frame.
• Mark both the front and rear lower control arm mounting cams.
• Alignment cams are offset washers that move the control arm slightly to adjust wheel angle.
• Clear marks make reassembly easier.

Step 10: Remove the Lower Control Arm

• Use a 22mm socket and 22mm wrench to loosen the front lower control arm cam bolt.
• Use a 22mm socket and 22mm wrench to loosen the rear lower control arm cam bolt.
• Remove the cam bolts, cam washers, and nuts while the arm is supported by the floor jack.
• Lower the floor jack slowly.
• Remove the lower control arm from the frame.
• If a cam bolt is seized inside the bushing, use penetrating oil and a pry bar. Badly seized bolts may need cutting and replacement.

Step 11: Install the New Lower Control Arm

• Lift the new lower control arm into place by hand.
• Apply a light coat of anti-seize compound to the cam bolt shanks.
• Install the front and rear cam bolts, cam washers, and nuts in their original positions.
• Line up the cam washers with your paint marks.
• Thread the nuts on by hand, but do not fully tighten yet.
• Final lower control arm cam bolt torque is Torque to 180 Nm (133 ft-lbs).

Step 12: Reconnect the Ball Joints

• Guide the lower ball joint stud into the steering knuckle by hand.
• Use a 24mm socket to tighten the lower ball joint nut to Torque to 160 Nm (118 ft-lbs).
• Install a new cotter pin with needle-nose pliers.
• Guide the upper ball joint stud into the steering knuckle by hand.
• Use a 19mm socket to tighten the upper ball joint nut to Torque to 110 Nm (81 ft-lbs).
• Install a new cotter pin with needle-nose pliers.

Step 13: Reconnect the Shock and Sway Bar Link

• Use the floor jack to raise or lower the lower control arm until the lower shock bolt hole lines up.
• Install the lower shock bolt by hand.
• Use a 19mm socket and 19mm wrench to tighten the lower shock bolt to Torque to 100 Nm (74 ft-lbs).
• Reconnect the sway bar link to the lower control arm.
• Use a 17mm socket and 17mm wrench to tighten the sway bar link nut to Torque to 70 Nm (52 ft-lbs).

Step 14: Tighten Control Arm Bolts at Ride Height

• Temporarily install the wheel with a 21mm socket and snug the lug nuts.
• Use the floor jack under the lower control arm to raise the suspension until it is near normal ride height.
• Use a 19mm socket and 19mm wrench to tighten the upper control arm pivot bolt to Torque to 135 Nm (100 ft-lbs).
• Use a 22mm socket and 22mm wrench to tighten the lower control arm cam bolts to Torque to 180 Nm (133 ft-lbs).
• This protects the new bushings.

Step 15: Reinstall the Wheel

• Use a 21mm socket to install the wheel lug nuts by hand.
• Lower your Tacoma until the tire just touches the ground.
• Use a torque wrench and 21mm socket to tighten the lug nuts in a star pattern to Torque to 113 Nm (83 ft-lbs).
• Fully lower the vehicle and remove the jack stands and wheel chocks.

Step 16: Repeat on the Other Side if Needed

• Use the same steps and tools on the opposite side if replacing control arms in pairs.
• Replacing suspension parts in pairs helps handling stay even side to side.
