🔧 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.
🔧 Required Tools
You'll need the following tools for this repair:
- Floor jack (rated 3-ton minimum)

- 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.
