I. Symptoms of a Damaged Steering Gear Ball Joint
The following eight symptoms may appear if there is a problem with the steering gear ball joint:
- Abnormal noise during steering: When the driver turns the steering wheel, a distinct noise can be heard from the steering column, indicating that the steering gear ball joint may lack lubrication.
Steering deviation: Besides improper dynamic balancing, a damaged steering gear ball joint can also cause the vehicle to deviate from its course, commonly known as being unable to drive in a straight line.
Significantly increased steering wheel play: Increased play refers to a larger ratio between the steering wheel’s turning angle and the vehicle’s steering angle. This is relatively rare but can still occur.
Steering wheel vibration: The steering wheel vibrates when turning, and steering becomes difficult.
Increased steering wheel play, inability to turn the steering wheel, or complete loss of connection and malfunction.
A rattling or clicking sound from the vehicle when driving on uneven roads.
A damaged steering ball joint can easily cause brake failure.
When driving at low speeds, you can clearly feel the car wheels shaking.
A damaged steering ball joint can have serious consequences. If not replaced, it can easily cause the entire steering mechanism to detach, leading to loss of control and, in severe cases, vehicle damage and fatalities. It is necessary to have the steering ball joint repaired or replaced at a professional repair shop as soon as possible.
II. How to Remove the Inner Steering Ball Joint
Remove the tire, remove the tie rod outer ball joint locating pin, and unscrew the outer ball joint fixing screw. This step is to separate the tire from the vehicle body to facilitate subsequent operations.
Loosen the outer ball joint and remove it. Remove the steering gear dust cover and pry open the inner ball joint retaining plate. This step requires careful handling to avoid damaging other parts.
Use a hose to insert the ball joint, and then install a new ball joint on top. Note that a new ball joint of the same specifications and model as the original must be used.
After replacing the ball joint, the toe-in needs to be adjusted to ensure driving stability and safety.
It is important to note that the steering gear, also known as the steering unit, is the most crucial component for a car’s steering function and a vital guarantee of driving safety. Therefore, caution must be exercised when disassembling and replacing the steering ball joint to avoid affecting driving safety.
