🔧 Altima - Control Arm Replacement

On your Altima, “control arm” usually means the front lower control arm (it locates the front wheel and contains the bushings and the ball joint). There are a couple of different arms/links on the car, so I need one quick detail to give you the exact, trim-correct steps and torque specs.

Difficulty Level: Intermediate | Estimated Time: 2-4 hours (both sides)

Quick questions (answer these 2 and I’ll tailor the steps):

• 🔎 Are you replacing the front lower control arm (left/right), or a rear suspension arm/link?
• 🔎 Are you replacing the entire control arm assembly (with ball joint), or just bushings/ball joint?

⚠️ Safety & Precautions

• ⚠️ Support the car with jack stands on solid ground; never rely on a floor jack alone.
• ⚠️ Keep hands clear of pinch points when lowering/raising the suspension.
• ⚠️ Your Altima is a hybrid: avoid touching orange high-voltage cables (you won’t need to disconnect HV for control arms, but be aware).
• ⚠️ If you separate a ball joint, the knuckle can move suddenly—support the knuckle/hub so it doesn’t yank the axle or brake hose.

📋 Before You Begin

• Park on level ground, shift to P, and chock the rear wheels.
• Crack the front lug nuts loose with a 21mm socket and breaker bar before lifting.
• Spray penetrating oil on the control arm-to-subframe bolts and the ball joint nut area.
• Important: Control arm bushings must be tightened at ride height (vehicle sitting at normal height). Tightening while the suspension hangs can tear bushings early.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Confirm which “control arm” you’re replacing

• Use a flashlight to look behind the front wheel.
• The front lower control arm is the larger arm that runs from the subframe to the steering knuckle (the ball joint end).
• Mark the arm and bolt locations with a paint marker and take a photo for reference.

Step 2: Lift and secure the front of the car

• Lift at the proper front jacking point using a floor jack.
• Set the car down onto jack stands and give the car a firm shake to confirm it’s stable.

Step 3: Remove the wheel

• Remove lug nuts using a 21mm socket and ratchet, then remove the wheel.

Step 4: Pause here so I can give the exact procedure + torque specs

• Reply with: Front lower / Rear and Left / Right, and whether you’re replacing the whole arm or bushings/ball joint.
• Once you confirm, I’ll provide the full removal/installation sequence and the correct Torque to XX Nm (YY ft-lbs) values for your Altima.

✅ After Repair

• Get a 4-wheel alignment as soon as possible (control arm changes affect alignment).
• Test drive at low speed first; listen for clunks over bumps and confirm straight tracking.
• Re-check lug nut torque after a short drive.
