Always replace shock absorbers in pairs, Tenneco urges
Oscar Oskarsson, senior training manager for Tenneco Aftermarket EMEA.

Tenneco, global manufacturer of Monroe shock absorbers, has warned that replacing only a single shock or strut could lead to unwanted performance and/or reliability issues for vehicle owners.

Like other vehicle systems and components, shock absorbers – which stroke an average of 2,800 cycles per kilometer – wear down over time.

When replacing one worn or damaged shock absorber, Tenneco say it is important to replace its counterpart on the other side of the vehicle to maintain consistent performance and prevent premature wear.

Oscar Oskarsson, senior training manager for Tenneco Aftermarket EMEA, said: “Shock absorbers have a direct impact on several key areas of vehicle performance, such as stopping distance, steering response, handling and the ability of the tires to contact with the road surface.

“It is critical that automotive service providers always replace both shocks on a single axle to ensure a safe and comfortable ride for their customers.”

Tenneco and Monroe recommend that automotive service providers check shock absorbers for wear or damage every 12,000 miles and always during the periodical service stop of the vehicle.

What to look for

When performing vehicle inspections, service providers should look for common signs of worn and damaged shocks and struts, damaged steering and suspension ball joints, poor steering response; fluid leaks from the shock or strut body; “cupped” and uneven tire wear; excessive vehicle bounce; and leaning or swaying during lane changes.

Tenneco supports its range of Monroe products via comprehensive training and vehicle diagnostic information through technical support platforms like the technicians advanced digital information system (TADIS), which includes thousands of helpful files designed for technicians, installers and other aftermarket professionals.
