Precision engineering

Enabling free movement in two planes at the same time, the ball-pin is a critical component. That’s why our ball-pins are manufactured from high-grade steel and machined to micron tolerances. Together with a polyoxymethylene nylon ball-pin seat, they provide optimum durability and smooth joint operation.

Extensive testing

Delphi ball joints undergo rigorous performance tests including angular stress testing, where the ball is rotated through its angular and rotational travel under load, as well as a pull and push out test, to measure the force required for it to break away from the housing. These important safety tests ensure the ball joint can withstand the same forces as the OE part.

Longer service intervals

We provide a range of sealed ball joints, that are lubed for life with a high-specification grease, to minimise maintenance requirements. Alongside our precision ball-pin finish and improved rubber boot design, they offer longer ball joint service intervals and better grease retention.

Greater protection

To help prevent damage to the joint’s internal components, all our ball joints come with a special chloroprene rubber cover. The new and improved formula maintains its durability even in extreme temperatures, providing added protection from road dirt or salt and allowing continued free movement of the ball joint for a longer lasting part.

Three-year warranty – available in UK

As a guarantee of our OE-quality standards, we offer a three-year or 36,000-mile warranty on all our ball joints. So, you can fit Delphi steering parts with complete confidence.

Cataphoretic coating

Like many of our steering parts, Delphi ball joints feature an environmentally friendly cataphoretic coating for tougher and longer lasting protection from corrosion caused by salt, dirt and water and other contaminants.

Tech Tip

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.

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.

Resource Highlights

Here we’re looking at finding the quickest way to identify a source of vibration or noise in a vehicle’s suspension.

It can be very tricky to investigate a customer’s complaint about a noise or vibration. Wireless chassis ear is a tool that lets you identify sources of noise and vibration much quicker.

Laura, our Delphi expert, shows you how it’s done using a Tesla Model Y as an example vehicle. She takes you through:

How to use it to find an issue, step by step

Why do I need a tool like this, when I can run a visual check?

You can run a visual check of course, but it’s hard during this sort of check to simulate the same loads the vehicle is under when it’s on the road.

What does the wireless chassis ear tool come with?

Typically it comes with four sensors (to attach to each wheel or suspension system), a wireless control box and headphones to listen in.

Can a wireless chassis ear tool be used to diagnose other faults?

Yes. You can use the tool to identify faults right across a vehicle’s engine, axles and chassis. It’s ideal for diagnosing faulty fuel injectors, bearings, gears, suspensions, transmissions, differentials and CV joints.
