🔧 Traverse - Front Lower Ball Joint Replacement

On your Traverse, the front lower ball joint connects the steering knuckle to the lower control arm. When it wears out, you can get clunks over bumps, loose steering feel, and uneven tire wear.

Assumption: This covers the common OEM-style repair: replacing the front lower control arm assembly (with ball joint), which is the most straightforward and reliable DIY method on this platform.

Difficulty Level: Advanced | Estimated Time: 2.5-4.5 hours (per side)

⚠️ Safety & Precautions

• ⚠️ Support the SUV with jack stands on solid ground; never rely on a jack.
• ⚠️ Keep hands clear when separating the ball joint—parts can “pop” loose suddenly.
• ⚠️ Do not let the steering knuckle hang by the brake hose/ABS wire; support it with a strap.
• ⚠️ Avoid over-extending the CV axle (front axle shaft) on AWD—don’t pull the knuckle outward aggressively.
• ⚠️ No battery disconnect is required for this repair.

📋 Before You Begin

• Park on level ground, set the parking brake, and chock the rear wheels.
• Use a breaker bar to crack the lug nuts loose 1/2 turn before lifting.
• Plan on getting a front-end alignment after replacement (recommended any time a control arm/ball joint is changed).
• Spray penetrant on fasteners 10 minutes early.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Lift and secure the front corner

• Use a floor jack to lift at the proper front jacking point, then set the vehicle on jack stands.
• Remove the wheel using a socket set.

Step 2: Support the steering knuckle

• Attach a bungee cord so the knuckle can’t drop or pull on the brake hose/ABS wire.
• Visually locate the ABS wire and make sure it has slack and won’t be stretched.

Step 3: Disconnect the sway bar end link from the control arm

• Hold the end link stud with the appropriate wrench and remove the nut with a socket set.
• Move the sway bar link out of the control arm hole.

Step 4: Remove the lower ball joint cotter pin and nut

• Straighten and remove the cotter pin using needle-nose pliers.
• Remove the ball joint nut using a socket set.

Step 5: Separate the ball joint from the steering knuckle

• Install a ball joint separator tool (specialty) between the knuckle and ball joint stud, then tighten until the joint pops free.
• If needed, strike the side of the knuckle boss (not the stud threads) with a hammer to help it release.
• Keep the nut loosely threaded for safety.

Step 6: Remove the lower control arm mounting bolts

• Mark the position of any cams/washers (if equipped) with a paint marker so you can reinstall in the same orientation.
• Remove the front and rear control arm-to-subframe fasteners using a breaker bar and socket set.
• Use a pry bar to carefully work the control arm out of the subframe.

Step 7: Install the new control arm

• Position the new control arm in place and start the mounting bolts by hand using a wrench set.
• Insert the ball joint stud into the knuckle and install the new nut by hand.
• Reconnect the sway bar end link and start the nut by hand.

Step 8: Torque fasteners (two-stage: snug now, final at ride height)

• Snug the control arm mounting bolts using a ratchet, but do not final-torque yet.
• Torque the ball joint nut using a torque wrench: Torque to 85 Nm (63 ft-lbs), then tighten further only as needed to align the cotter pin hole; install a new cotter pin using needle-nose pliers.
• Torque the sway bar end link nut using a torque wrench: Torque to 65 Nm (48 ft-lbs).
• Final-torque the control arm-to-subframe bolts ONLY with the suspension at normal ride height (this prevents bushing twist and premature bushing failure):
  • Support the outer end of the control arm/knuckle with the floor jack and raise until the vehicle just begins to lift off the stand slightly (simulates ride height).
  • Torque the control arm mounting fasteners with a torque wrench: Torque to 150 Nm (111 ft-lbs).

Step 9: Reinstall the wheel and lower the vehicle

• Install the wheel and hand-tighten lug nuts using a socket set.
• Lower off the jack stands using the floor jack.
• Torque the lug nuts in a star pattern with a torque wrench: Torque to 190 Nm (140 ft-lbs).

✅ After Repair

• Road test at low speed first. Listen for clunks and confirm steering feels stable.
• Recheck the ball joint cotter pin is fully installed and bent over.
• Get a professional front alignment as soon as possible.
• After 25-50 miles, recheck lug nut torque using a torque wrench.
