Worn Ball Joints
Symptoms
Clunking over bumps from the front end. Vague steering. Uneven tyre wear. Steering wheel vibration.
Cause
The EJ/EH uses ball joints (upper and lower) in the front suspension, which wear with age, mileage, and Australian road conditions. Worn ball joints allow the stub axle to move relative to the control arms, which directly affects steering precision and wheel alignment.
Fix
Replace all four ball joints (upper and lower, both sides).
Budget $150-300 for a complete ball joint set.
Replacement is a straightforward job with basic tools, though a ball joint press or separator tool is helpful.
Always get a wheel alignment after ball joint replacement.
