🔧 Altima - Front Lower Ball Joint Replacement

The front lower ball joints on your Altima are part of the front lower control arm assembly. Nissan service procedure replaces the lower control arm rather than pressing the ball joint out separately.

This repair restores steering and suspension safety when the ball joint is loose, clunking, torn, or failed. Both sides should be inspected, and if one side is worn, replacing both front lower control arms is strongly recommended.

Difficulty Level: Intermediate | Estimated Time: 2-4 hours

⚠️ Safety & Precautions

• ⚠️ Do not drive with a loose or separated ball joint. It can cause loss of steering control.
• ⚠️ Support your Altima with jack stands only. Never work under a vehicle held up by a floor jack.
• ⚠️ The front suspension is load-bearing. Keep hands clear when separating the ball joint from the steering knuckle.
• ⚠️ Do not hammer directly on the ball joint stud threads.
• ⚠️ Replace the cotter pin and any one-time-use locking nuts removed during the repair.
• ⚠️ A wheel alignment is required after lower control arm replacement.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Loosen the Front Wheel

• Use a 19mm socket and 1/2-inch drive breaker bar to loosen the front lug nuts about half a turn.
• Do not remove the lug nuts yet.
• Loosen wheels before lifting.

Step 2: Lift and Support the Vehicle

• Use the floor jack at the front center jacking point or approved side jacking point.
• Place jack stands under the proper front support points.
• Lower your Altima gently onto the jack stands.
• Lightly shake the vehicle by hand to confirm it is stable.

Step 3: Remove the Front Wheel

• Use the 19mm socket to remove the loosened lug nuts.
• Remove the wheel and place it flat under the side of the vehicle as an extra safety backup.

Step 4: Inspect the Lower Control Arm Area

• Use safety glasses and mechanic gloves.
• Locate the lower control arm. It is the large metal arm connecting the frame to the bottom of the steering knuckle.
• Locate the ball joint at the outer end of the control arm, near the brake rotor.
• Use penetrating oil on the ball joint nut and control arm mounting bolts.

Step 5: Disconnect the Stabilizer Bar Link if Needed

• Use a 14mm wrench or 17mm wrench as applicable to hold the stabilizer link stud.
• Use a 14mm socket or 17mm socket if available, or matching wrench, to remove the stabilizer link nut from the lower control arm if it blocks removal.
• Move the stabilizer link aside.

Step 6: Remove the Ball Joint Cotter Pin and Nut

• Use needle-nose pliers to straighten and pull out the cotter pin from the ball joint stud.
• A cotter pin is a small bent safety pin that keeps the nut from backing off.
• Use a 19mm socket or 19mm wrench to loosen and remove the ball joint castle nut.
• A castle nut has slots on top for the cotter pin.

Step 7: Separate the Ball Joint from the Steering Knuckle

• Install the ball joint separator between the lower control arm ball joint and the steering knuckle.
• Use a 3/8-inch drive ratchet or suitable wrench on the separator screw to press the joint loose.
• Support the steering knuckle by hand as the taper releases.
• Do not pull hard on the axle shaft or brake hose.
• The pop sound is normal.

Step 8: Mark the Control Arm Bolt Positions

• Use a paint marker to mark the position of the control arm mounting bolts and washers before removal.
• This helps keep the alignment close enough to drive carefully to an alignment shop.

Step 9: Remove the Rear Control Arm Mounting Bolt

• Use a 21mm socket and 1/2-inch drive breaker bar to loosen the rear lower control arm mounting bolt.
• Use a 21mm wrench if needed to hold the nut.
• Remove the bolt and nut.

Step 10: Remove the Front Control Arm Mounting Bolt

• Use a 22mm socket and 1/2-inch drive breaker bar to loosen the front lower control arm mounting bolt.
• Use a 22mm wrench if needed to hold the nut.
• Remove the bolt and nut.

Step 11: Remove the Lower Control Arm

• Use a pry bar 18-inch to gently work the control arm out of the subframe mounts.
• Use a rubber mallet to tap the arm free if it is stuck.
• Do not bend the subframe brackets.

Step 12: Install the New Lower Control Arm

• Position the new lower control arm in the subframe mounts by hand.
• Use the rubber mallet only for light tapping if needed.
• Install the front and rear mounting bolts finger-tight only.
• Do not fully tighten the inner control arm bolts while the suspension is hanging.

Step 13: Connect the New Ball Joint to the Steering Knuckle

• Guide the new ball joint stud into the steering knuckle by hand.
• Install the new or supplied ball joint nut.
• Use a 19mm socket and 1/2-inch drive torque wrench to tighten the ball joint nut to Torque to 83 Nm (61 ft-lbs).
• Install a new ball joint cotter pin with needle-nose pliers. If the hole does not line up, tighten the nut slightly until it lines up. Do not loosen it to align the pin.

Step 14: Reconnect the Stabilizer Bar Link

• Install the stabilizer link back into the lower control arm if removed.
• Use a 14mm wrench or 17mm wrench to hold the stud.
• Use the matching socket or wrench to tighten the stabilizer link nut to Torque to 49 Nm (36 ft-lbs).

Step 15: Load the Suspension Before Final Tightening

• Use the floor jack under the outer lower control arm to raise it until the suspension sits near normal ride height.
• This prevents twisting the rubber bushings when the car is lowered.
• A bushing is a rubber mount that lets the control arm move smoothly and quietly.

Step 16: Tighten the Inner Control Arm Bolts

• Use a 21mm socket, 22mm socket, and 1/2-inch drive torque wrench to tighten the lower control arm mounting bolts.
• Tighten the front lower control arm bolt to Torque to 137 Nm (101 ft-lbs).
• Tighten the rear lower control arm bolt to Torque to 137 Nm (101 ft-lbs).

Step 17: Reinstall the Wheel

• Place the wheel back on the hub by hand.
• Install the lug nuts finger-tight.
• Use the 19mm socket to snug the lug nuts in a star pattern.

Step 18: Lower the Vehicle and Torque the Lug Nuts

• Use the floor jack to lift the vehicle slightly off the jack stands.
• Remove the jack stands.
• Lower your Altima until the tire just touches the ground.
• Use the 19mm socket and 1/2-inch drive torque wrench to tighten the lug nuts in a star pattern to Torque to 113 Nm (83 ft-lbs).
• Fully lower the vehicle and remove the floor jack.

---

✅ After Repair

• ✅ Turn the steering wheel left and right while parked. Listen for clunks or binding.
• ✅ Test drive slowly at first. Keep speed low and listen for abnormal noises.
• ✅ Recheck the lug nut torque after a short drive using the 19mm socket and 1/2-inch drive torque wrench.
• ✅ Schedule a front wheel alignment immediately. Lower control arm replacement changes alignment angles.
• ✅ If replacing one side only, inspect the opposite lower ball joint and control arm bushing for cracking or looseness.
