🔧 Accord - Control Arm Replacement

On your Accord, “control arms” can mean the front lower control arm (most common) or one of the rear multi-link arms. The steps, parts, and torque specs are different depending on which arm(s) you’re replacing.

Quick questions (so I give the correct procedure): 1) Are you replacing front control arms or rear control arms? 2) Are you replacing the whole arm assembly (with bushing/ball joint) or just bushings?

Difficulty Level: Intermediate | Estimated Time: 1.5-3.0 hours per side (front lower arm)

⚠️ Safety & Precautions

• 🛑 Support the car with jack stands on solid points; never rely on a floor jack alone.
• 🧤 Wear safety glasses; separating a ball joint can release suddenly.
• 🔥 Work on a cool suspension; avoid touching hot exhaust components near the front subframe.
• 📏 Plan for an alignment after control arm work; tire wear and pulling can happen if skipped.
• 🔋 Battery disconnect is not required for front lower control arm replacement.

📋 Before You Begin

• 🅿️ Park on level ground, set the parking brake, and place wheel chocks behind the rear tires.
• 🔓 Slightly loosen the front wheel lug nuts using a 19mm socket and breaker bar before lifting.
• 🧴 Spray penetrating oil on the control arm bolts and the ball joint nut using penetrating oil; wait 5–10 minutes.
• 🖊️ Use a paint marker to mark bolt positions/washers so you can reassemble the same way.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Lift and secure the front end

• Use a floor jack (rated 3-ton minimum) to lift the front of the car at the approved front jacking point.
• Set the car down onto jack stands (rated 3-ton minimum) placed at strong frame/subframe points.
• Remove the wheel using a 19mm socket.

Step 2: Locate the front lower control arm and ball joint

• The front lower control arm is the large arm under the front suspension that connects the knuckle to the subframe.
• The ball joint is the pivot at the outer end (near the wheel). A ball joint separator is a tool that pops the joint apart without damaging parts.

Step 3: Remove the ball joint cotter pin and nut

• Straighten and remove the cotter pin using needle-nose pliers.
• Remove the ball joint castle nut using the correct size socket set (10mm–22mm, 1/2") and breaker bar (1/2").
• Don’t reuse cotter pins.

Step 4: Separate the ball joint from the steering knuckle

• Install and operate the ball joint separator (specialty) until the joint “pops” free.
• If needed, tap the knuckle boss with a hammer (2 lb) while keeping the separator tensioned.
• Use a pry bar (24") to gently guide the control arm down once separated.

Step 5: Remove the control arm mounting bolts

• Support the control arm with your hand or a floor jack (rated 3-ton minimum) so it doesn’t drop suddenly.
• Remove the inner control arm bolts/nuts using a socket set (10mm–22mm, 1/2") and wrench set (10mm–22mm).
• Remove the control arm from the subframe.

Step 6: Install the new control arm (do not final-tighten bushings yet)

• Position the new arm in place and start all mounting bolts by hand.
• Tighten the mounting bolts snug using a ratchet from your socket set (10mm–22mm, 1/2"), but do not fully torque yet.
• Hand-start bolts to avoid cross-threading.

Step 7: Reconnect the ball joint to the knuckle

• Guide the ball joint stud into the knuckle using a pry bar (24") as needed.
• Install the new castle nut using the correct size socket.
• Torque to OEM specification using a torque wrench, then continue tightening slightly until the cotter pin hole aligns.
• Install a new cotter pin using needle-nose pliers and bend the ends over.

Step 8: Final-torque the control arm bushing bolts at ride height

• Put the wheel back on using a 19mm socket and snug the lug nuts.
• Lower the car so the suspension is at normal ride height (vehicle on the ground).
• Torque the control arm mounting bolts to OEM specification using a torque wrench.
• This prevents bushing “preload,” which can tear the bushing early.

Step 9: Torque the wheel lug nuts

• Use a torque wrench (10–250 Nm range) and 19mm socket to tighten the lug nuts in a star pattern.
• Torque to OEM specification.

✅ After Repair

• 🧪 Road test at low speed first; listen for clunks over small bumps.
• 🔍 Recheck that the cotter pin is installed and bent correctly.
• 📏 Get a 4-wheel alignment as soon as possible.
• 🛞 Watch the steering wheel position; off-center indicates alignment is needed.
