Building Of A Driveshaft

If you like to crawl in boulders you've probably sacrificed a driveshaft to the ravages of rock. Whether it be a simple bend, dent, or a complete collapse, such damage is all too common. As such, driveshaft shops are used to re-tubing or replacing what we destroy.

To further understand what it takes to assemble a driveshaft from scratch, we took a trip to Phoenix Rack & Axle, a driveline specialty shop located in Phoenix, Arizona. The shop builds standard and custom driveshafts for all types of vehicles. We were interested in the construction of one of its long-travel 'shafts.

Owner Bernie Thompson showed us the steps his shop uses in constructing a 'shaft from base components. While a standard auto driveshaft may use tubing as thin as 1/16-inch-wall thickness, shafts for rock-crawlers are often built from 0.120-inch to 0.250-inch-wall tubing for added strength and the ability to be dragged across boulders as needed.
