Dana was founded in the United States in 1904 by Clarence Spicer, who developed an early automotive driveshaft, and it grew from the Spicer Manufacturing Company into a global supplier of drivetrain technology with headquarters in Ohio. Its products have been fitted to cars, trucks and working machines for well over a century.

The company is known for axles, driveshafts, transmissions and related components used in light vehicles, commercial trucks, buses and off-highway machinery. Because Dana parts sit between the engine and the driving wheels, drivetrain service knowledge is central to keeping Dana-equipped vehicles working reliably.

Workshop manuals in this section cover the components themselves: axle and differential overhaul, driveshaft and universal-joint service, gearing and torque specifications, seals and bearings, plus the surrounding systems such as brakes and suspension that are serviced alongside the drivetrain on the vehicle. Correct torque values and preload settings are particularly important on Dana axles, where component alignment determines service life.

Fleet workshops, truck and four-wheel-drive specialists, agricultural and construction mechanics, and DIY owners maintaining Dana-equipped vehicles will find precise factory service data useful for correct, durable and safe repairs. Reliable drivetrain service data helps workshops avoid comebacks and keeps trucks, buses and machines working on the road and in the field. Owners of older trucks and machinery in particular benefit from exact data on component identification and rebuild limits.
