🛠️When Should You Replace the Rear Knuckle?
Below are the most common signs and reasons indicating a replacement is needed:
| Symptom | Cause Explanation | Replace? |
|---|---|---|
| 1. Uneven tire wear on one side | A bent knuckle alters rear camber or toe alignment, causing irregular tire contact | ✅ Yes |
| 2. Knocking or clunking noise over bumps | Cracks or looseness in the knuckle create play in the suspension, leading to impact noises | ✅ Yes |
| 3. Vehicle pulls to one side or alignment won’t hold | The knuckle may be deformed from impact, making proper alignment impossible | ✅ Yes |
| 4. Visible cracks or physical damage | Especially in snowy regions with road salt, aluminum knuckles can corrode and crack over time | ✅ Yes |
| 5. After severe bottoming out or collision | Even if no damage is visible, internal stress or bending may compromise safety and alignment | ✅ Recommended |
