🔧 Legacy - Ball Joint Replacement

On your Legacy, “ball joint replacement” usually refers to the front lower ball joints (they press into the steering knuckle and are held by a pinch bolt). The exact procedure and torque specs change depending on whether it’s the front lower ball joints or a different joint/link in the rear suspension.

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

⚠️ Safety & Precautions

• ⚠️ Support the car on jack stands; never rely on a jack alone.
• ⚠️ Don’t pull or let the axle hang by the CV joint; support the knuckle/hub as you work.
• ⚠️ Use eye protection when separating joints; parts can pop loose suddenly.
• ⚠️ If you use a hammer near the knuckle, avoid striking the CV axle threads.

📋 Before You Begin

• Park on level ground, set the parking brake, and chock the rear wheels.
• Spray penetrating oil on the ball joint pinch bolt area and let it soak 10–15 minutes.
• Two quick questions so I give you the exact OEM-correct steps and torque specs:
• 🧭 Are you replacing the front lower ball joints (most common), or are you working on a rear suspension joint/link?
• 🔩 Are you doing left, right, or both sides?

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Confirm the exact ball joint location

• I’ll provide the full procedure with the correct Subaru torque specs as soon as you answer the two questions above.
• This matters because the front lower ball joint uses a pinch-bolt knuckle design, while rear components are different and can require different hardware and steps.

✅ After Repair

• Plan for a front-end alignment after front suspension work to prevent tire wear.
• Do a slow test drive and listen for clunks over bumps.
• Recheck all fasteners for tightness after the first short drive.
