Nowadays, most passenger cars use rack and pinion power steering systems, and some newer cars and trucks even use electric power steering. But that doesn't mean you won't come across vehicles with old school pitman arm power steering setups — especially in old trucks and classic cars.

So if you have a desire to learn something about how these old, but sturdy steering systems work, fall in! Sgt. Steering is about to break it down Barney-style for you maggots!

UPDATE: Apparently we wrote about this a year ago too. Sometimes things are so awesome you just get repeatedly wowed by them.
