Solutions to Inherent Design Flaws

Jonathan Allen, Regional Marketing Manager at Federal-Mogul Motorparts, discusses the solutions available to aftermarket customers when dealing with an inherent design flaw in an OE quality component.

A knowledgeable motor factor can offer customers an enhanced service that includes troubleshooting advice, promoting customer loyalty and the ability to upsell. It’s a view shared by Federal-Mogul Motorparts’ steering and suspension brand MOOG, which identifies OE components that suffer inherent design weaknesses and then works to develop an OE quality solution for aftermarket customers. New product information is provided in the form of Easy Solutions Bulletins (ESB), educating parts advisors and sales staff on common issues and available solutions for the benefit of end-user customers.

BMW arm bush replacement

“Bush replacement is often time consuming and is rarely a technician’s favourite job, but the rear track trailing arm bushes of E36, E46 and E83 BMW models are notoriously awkward,” explains Jonathan. “To replace a like-for- like standard bush, the time intensive process involves dismantling parts of the rear axle to gain access to the trailing arm. MOOG has altered the design of the bush by removing its collar, so the component can now be replaced using a specially designed tool, and without dismantling the rear axle. Through MOOG’s product, a factor can offer its customer a safer and quicker alternative to carrying out the job.”

Renault dust boot wear

Damaged dust boots on certain Renault models, such as the Scenic I and Kangoo, can lead to premature ball joint corrosion and, ultimately, component failure, due to water ingress penetrating the ball pin housing. MOOG’s solution adds a plastic protection plate to the ball joint kit, providing a solid and smooth surface, which limits the chance of damage to the dust boot and increases the expected component life. These Renault models are now reaching an age where the majority will be on their second, or even third, set of chassis components and require more regular maintenance; such upgrades can help keep cars on the road for longer and reduce costs for customers on a budget.

Land Rover track control arm

The adjustable rear track control arm fitted to Land Rover Freelander is susceptible to rust, especially in the component’s threaded area, which is exposed to road dirt, water and winter salt, and is often only noticed during wheel alignment. MOOG applies a cataphoresis coating and grease to the thread of its part, which maximises rust protection without negatively impacting component adjustability and ensuring trouble-free adjustment during service.

Volkswagen wishbone bushing

“MOOG constantly monitors the market for opportunities to develop valuable solutions to common issues, such as the design of the vertical bush, as used in a number of popular VAG models, including the Audi A3, Volkswagen Golf IV, Seat Leon I and Skoda Octavia,” explains Jonathan. “The OE component features a rubber section manufactured with voided areas and inferior rigidity, resulting in excessive movement and, in some cases, generating an unbalanced feel in normal driving conditions. MOOG uses a more rigid, less malleable rubber, and has redesigned the vertical rubber bush in order to prevent excessive movement of the silent block. With fitment of this part, an improved driving experience and longer component life can be expected.”
