Gabriel® Answerman Heavy-Duty Tips
Review these tips before you replace your shocks
Take the Heat Test
If ride deterioration is experienced and there is suspicion that a shock has failed internally, perform the following “SHOCK HEAT TEST” within a few minutes of operating the equipment.
Shock absorbers function at temperatures ranging from ambient to 350° F. Shocks dampen the oscillation of the truck’s springs by transforming energy produced by the spring to heat and dissipating it. As a result, the shock should be slightly warm to hot to the touch after normal use.
|1.||Drive the vehicle at moderate speeds for at least 15 minutes.|
|2.||All shock absorbers should be warmer than the chassis. Within a few minutes of driving the vehicle, touch each shock absorber carefully on its body below the dust cover or tube, after first touching a nearby part of the chassis to establish a reference ambient temperature of the metal. Note if shocks aren’t warm.|
|3.||Suspect failure in any shock absorber that is noticeably cooler than its mate on the other end of the axle. Different temperatures from axle to axle do not indicate failures, but cooler temperatures on any one axle does warrant removal and examination of the cooler shock absorber.|
|4.||To inspect for an internal failure, remove and shake the suspected shock. Listen for the sound of metal parts rattling inside, which can indicate internal failure.|
Gabriel cannot determine whether any particular customer is qualified to check or replace ride control, shocks or struts. Customers must make their own assessments of their experience, skills and knowledge and take responsibility for all results and if in doubt, seek the assistance of a qualified trained mechanic.

Every vehicle is delivered with an OEM owner’s manual. If you cannot locate yours, several publications exist that will provide you with the specifications for the parts on the vehicle you are about to repair. Read the OEM manual specific to the make and model of your vehicle and the instructions that accompany your Gabriel product before undertaking any repair or replacement project. Always seek the advice or assistance of a qualified, trained professional when needed.
Before starting and vehicle repair or replacement project, you must have the proper training, tools, equipment and experience necessary to safely and correctly complete the project. This is especially important for anyone attempting to replace a worn strut or shock absorber, because failure to remove the worn part or install the replacement parts correctly on your vehicle may result in personal injury or damage to property.
