Ball Joints

Ball joints are chassis parts that connect the steering knuckles to the control arms. The ball and socket design of the joint allows it to swivel so the knuckles can pivot as the wheels are steered, and to arc so the knuckles can follow the vertical motions of the suspension as it reacts to changes in the road surface Ball joints should be replaced when the amount of play or movement in the joint exceeds the maximum allowed by the vehicle manufacturer. A loose ball joint can cause misalignment, uneven tire wear, sometimes a steering pulls to one side, or suspension noise.

Your customers may want to believe that noise was coming from the car next to them. Or they may just turn up the radio. But the tell-tale sound of a failing ball joint is a cry for help - and an OE quality replacement.
The Delphi Difference
* High strength, smooth operation
* High quality forgings
* Surface finish machined to micron tolerances
* OE quality plastic ball pin bearing
* Extreme tested to meet OE standards
Ball Joint Tech Tips
* Delphi is advising technicians to help ensure a quality steering and suspension repair by replacing the entire ball joint component where the rubber boot is split, cracked, damaged or missing. In these instances, there is a high probability that damage to the ball joint may have occurred, indicating the joint is likely to fail even after the boot cover has been replaced. Replacing the entire ball joint component can help avoid potential premature failure, which can be safety-critical and costly. This can also help avoid potential warranty invalidations.
* By replacing the boot only and not the complete ball joint unit, the rubber boot could potentially seal in the damaging substances the joint has been exposed to, resulting in accelerated rust and corrosive damage to the joint. In addition, the ball joint is designed to operate with a grease lubricant. A defective boot could lead to a loss of this essential lubrication, as it may be washed away with water, dry out or become coated with dirt and other debris.
* Delphi also recommends being aware of 'universal' rubber boots and associated fitment-cable ties intended for repair and/or modification of the part. The term 'universal' can be misleading, as there are many variations of boots used in any given range of steering and suspension products with each rubber boot specifically designed and manufactured for use with its specific ball joint.
* Delphi ball joints adhere to global OE technical requirements and undergo testing focused on strength and durability performance, safety critical tests for a safer driving experience. The ball joint push out test measures the force required to push out / remove the ball-pin from the housing. It is an important safety check to help ensure the part can withstand forces applied to the vehicle suspension system in real road conditions. The ball joint pull out test measures the force required to pull the ball-pin out from the housing. If the force required to remove the ball-pin is below the OE spec, there is a risk the joint could fail during normal driving conditions, causing the vehicle to lose directional control.
* Additionally, Delphi's new dust cover design features an improved Chloroprene Rubber (CR) formula that helps maintain its durability even in extreme temperatures, helping to protect the internal components and support the continued free movement of the ball joint.

Delphi's improved dust cover
Delphi's improved dust cover helps address one of the most common reasons for premature steering part failure, splitting of the rubber boot. Typically when a dust cover splits, it allows salt and dirt to access the internal part components. This typically results in corrosion and prevents free movement of the ball joint. Delphi's new dust cover design features an improved Chloroprene Rubber (CR) formula that maintains its durability even in extreme temperatures, helping protect the internal components and continued free movement of the ball joint.
WORN BALL JOINT TECH TIPS
If your car makes noises while turning, it is a sign of a worn ball joint. Ball joints can be worn out if not lubricated properly or are in prolonged used for a long time. Worn ball joints should be replaced.
Reman Turbochargers
Measures the force required to push out / remove the ball-pin from the housing. It is an important safety check to ensure the part can withstand forces applied to the vehicle suspension system in real road conditions. If the force required to push the ball-pin out from its housing is below OE requirements, there is a risk the joint could fail. Delphi performed within the one percent tolerance required.
Ball joint pull out test
Measures the force required to pull the ball-pin out from the housing. If the force required to remove the ball-pin is below the OE spec, there is a risk the joint could fail during normal driving conditions, causing the vehicle to lose directional control since the wheel hub would no longer be anchored to the suspension arm. Delphi performed within one percent required of the OE specs.

The rotational test measures the force required to rotate the ball-pin within the housing and validates the smooth movement of the steering joint. The break-away test measures the force required to move the ball-pin when the steering wheel turns. Delphi matched the OE part in both torque tests. The competitors ranged from below the accepted range to four times the torque required. With higher torque values than the OE, steering could be stiff and difficult to self center after turning, rendering the vehicle unpredictable. If lower than the OE, the steering could feel loose and unstable.
Ball-pin angular movement test
If the ball-pin angular movement is lower than the OE specification it could restrict the movement of the steering or the suspension, causing excessive stress on other system components and leading to premature failure of the parts. In this test, Delphi matched the OE specifications.
Ball joint pull out test
Measures the force required to pull the ball-pin out from the housing. If the force required to remove the ball-pin is below the OE spec, there is a risk the joint could fail during normal driving conditions, causing the vehicle to lose directional control since the wheel hub would no longer be anchored to the suspension arm. Again, Delphi performed within one percent required of the OE specs.
HOW TO REPLACE BALL JOINTS

Ball Joint by Mevotech

Ball joints act as the pivot point for suspension articulation. Ball joints are designed to allow the suspension to move independently without interfering with the action of the wheel. This independent motion isolates the movement of the car or truck wheel from the chassis of the vehicle, creating a smooth and quiet ride.

Description
The two most common suspension system types are:
Dual Wishbone - includes a ball joint mounted to each the upper and the lower suspension control arms.
MacPherson Strut - includes a single ball joint located on the lower control arm.
In the aftermarket, suspension systems continue to experience wear and fatigue throughout the life of the vehicle. Factors that can contribute to wear and fatigue are road conditions, weather, and vehicle load and weight changes.
Types
There are 3 basic types of ball joints that are used in suspension systems:
* Press in - a press in ball joint design works on the principle of friction, or interference. The ball joint is larger than the hole inside the control arm or knuckle. When the ball joint is pressed into the control arm, a high amount of friction is generated that holds the ball joint tightly in place.
* Bolt In - a bolt in ball joint uses a mounting flange that bolts on to the control arm using 3 or more bolts and nuts. Many of the OEM ball joints on this application will come riveted only on the original vehicle. As they wear and need to be replaced, the rivets are removed, and the ball joint is replaced with an aftermarket bolt in design.
* Unitized - a unitized ball joint application replaces the individual ball joint. This design completely integrates the ball joint pivot into the design and construction of the control arm assembly, forming one solid container arm. This design has become very popular with the use of aluminum design control arms. Replacement of unitized ball joints requires the entire control arm assembly to be replaced.
To compensate for wear on control arm receptacles, Mevotech X Factor ball joints are manufactured with the following features:
* High friction knurlingaround the outside of the ball joint housing to provide the control arm maximum grip to keep the ball joint firmly in place.
* Blue polyurethane bootsto prevent moisture and foreign particles from entering the internal contract area
* Black oxide coating to prevent rust and corrosion from affecting the ball joint
* Metal to metal internal designsto allow ball joints to be swiveled and greased at regular intervals, increasing overall life span and durability.
Purpose
Ball joints act as the pivot point for suspension articulation. Ball joints are designed to allow the suspension to move independently without interfering with the action of the wheel. This independent motion isolates the movement of the car or truck wheel from the chassis of the vehicle, creating a smooth and quiet ride. Depending on the location of the ball joint, it will be either a load-bearing or a non load-bearing joint. Load-bearing ball joints are subject to continual load stress, and because of this, they must be inspected frequently to ensure optimal performance. Excessively worn ball joints require replacement.
Technology

* Metal design of internal components - Internal metal designs are widely used in the manufacture of Mevotech X Factor ball joints. These designs incorporate highly durable upper and lower metal bearings that surround the ball joint stud and ball, and they include grease fittings to allow for grease and lubrication to be injected into the central area to prolong the life of the ball joint.
* Greaseable - Greaseable ball joints enable the ball joint to be serviced, to flush out old grease and contaminants by injecting new grease during inspection and maintenance routines.
* Knurling - The knurling process on the outer housing of the ball joint cause press in ball joints to grip and mate with the control arm optimally. Ball joints must be held firmly in place within the control arm in order to function properly. Knurling is an important component of the aftermarket ball joint because it compensates for the wear and deformation of the control arm receptacle.
* Black oxide coating- The black oxide coating provides high resistance to variable corrosion factors such as road debris and adverse road and weather conditions, ensuring prolonged life of the ball joint.
