Seasoned car guys can often identify cars at first sight.

But how many of us can easily ID a vehicle’s rear axle? It’s a handy skill to have for sure — especially when you’re scouring a junkyard for a replacement axle or evaluating a potential project vehicle. We’ve put together this visual guide to help you hone your rear axle spotting skills.

It’s worth noting that rear axles can sometimes be positively identified by a casting number and date stamped on the differential cover or axle tube. However, road debris, dirt, grime, and general age can obscure these numbers. Fortunately, you can tell a lot about a rear axle by its shape and number of bolts on the differential housing.
