How to Identify a Dana Rear End


The Dana Corporation manufactures vehicle differentials in tandem with the Spicer Corporation, which, according to the National Institute of Standards and Technology, “is North America‚Äôs largest independent manufacturer of automotive driveshafts and related components.” Dana/Spicer rear-end units are popular for heavy-duty applications and commonly found in trucks, but also found in cars, off-road and construction vehicles. Identification is accomplished both visually and by locating tags attached to the rear-end housing unit. Dana/Spicer Corporation tags contain the necessary information for complete identification.

Step 1

Count the number of bolts on the inspection cover of the rear-end housing. The inspection cover faces the back of the vehicle and can be seen by looking forward from the rear of the car, under the license plate. Some Dana units share the same number of bolts, however, this aids in a process of elimination. Compare the bolt number to the Dana section of Nationwide Parts’ Differential Identification Charts (see References).
