Trussing An Axle The Right WayPosted in How To: Transmission Drivetrain on March 1, 2012 0) (
Imagine your 4x4 equipped with larger-than-stock tires ripping across the desert or mud bog when all of a sudden a hidden berm, log, or ditch sends you skyward. You land with a crash and likely do one of two things: get out and check for damage, or spin a U-turn and do it again because it was so much fun. Either way you may want to consider just how much abuse your axles are taking.?>
When OEMs source an axlehousing they have two priorities. Will it do the job required by the stock vehicle, and at what cost? When we four-wheelers get a hold of an axle we inevitably put greater stresses and abuse on it than the OEMs or axle manufacturers ever required.?>
One way to care for your gear-spinning, shaft-protecting axlehousing is to install a truss. A truss is a simple or elaborate steel structure that gussets and supports the axletubes in such a way as to deter bending from excessive use and abuse, something we wheelers call fun.
