⚠️ Safety Warnings

Important safety information - read before proceeding

•Always use jack stands when working under a vehicle.
•Allow the vehicle to cool before working on suspension components.

Symptoms

•Clunking or popping noises when turning or going over bumps
•Excessive vibration in the steering wheel
•Uneven tire wear
•Steering feels loose or imprecise

Diagnostic Steps

1
Inspect the ball joints for any visible signs of damage, such as cracks or excessive grease leakage.
2
With the vehicle on a level surface, lift the front of the vehicle using a jack and secure it with jack stands. Grasp the wheel at the 12 o'clock and 6 o'clock positions and attempt to rock it. Any noticeable movement indicates wear.
3
Push down on the front of the vehicle and release. If it bounces excessively and does not settle quickly, the ball joints may be worn.
4
Use a ball joint separator tool to check for play in the ball joint while the suspension is loaded and unloaded.
5
Inspect the vehicle alignment to see if it’s within specifications; misalignment can indicate worn ball joints.
