Are Ball Joints Maintenance-Free? What Modern Drivers Should Understand About Sealed Components 

Ball joints are a key component of a vehicle’s suspension. Ball joints attach the control arms to the steering knuckle, which allows the wheels to move freely over rough terrain. In addition to providing for the free movement of the wheels, ball joints also provide control for the steering and assist in maintaining the stability of the vehicle. Although most modern vehicles now have sealed ball joints, they will eventually wear out. Therefore, it is important for all drivers to be aware of what ball joints do, and why it is so important to inspect them regularly.

Understanding Sealed Ball Joints In Modern Vehicles

The sealed type of ball joint has been manufactured in such a way that it will retain its lubricating fluid within itself. In addition, the boot that covers the ball joint will prevent dust and water from being introduced into the unit.

Unlike the older style of ball joint, which was serviceable by means of a grease gun, most sealed ball joints do not contain a grease port. This is due to the fact that they require less maintenance than earlier models of ball joints, and therefore make vehicle maintenance simpler. Although the sealed ball joint requires minimal maintenance by Motor Medics, there are times when the internal lubricant will break down over time. At other times, the protective boot around the ball joint will crack or split.

Warning Signs Of Worn Ball Joints

A number of noticeable symptoms will occur if a vehicle’s ball joints are worn. Drivers may notice a “clunking” sound while driving over bumps or making turns at slow speeds. Additionally, the driver may experience a feeling of looseness in the steering wheel, as well as a lack of responsiveness in the steering system.

Many other components within the suspension system can create identical issues. Therefore, it is important for drivers to have their vehicle inspected by a qualified technician in order to determine what is causing the issue.

Can Sealed Ball Joints Be Repaired Or Lubricated?

A majority of sealed ball joints are made to be replaced as opposed to being maintained internally. Applying lubricant to a sealed ball joint without having the proper tools/equipment could cause damage to the protective boot or allow contamination. There may exist specialized procedures for certain components. Specialized procedures, however, should only be performed if the manufacturer approves them. Drilling into a sealed joint or attempting a “do-it-yourself” lubrication method could create a safety issue. When it has been determined that there is too much movement (play) within the joint or structural damage has occurred to the component, the most common course of action is to replace the component. Drivers looking for quality Auto Repair in Savannah, GA service like Motor Medics will want to look for experienced mechanics that can evaluate your car’s suspension system and provide you with recommended replacement components.
