i'm looking at buying a 94 F350 4x4 crewcab TD. this truck has a manual feeling at idle but once you get going it is fine. i'm kinda new to diesels, but doesn't the PS run off of an injection system of some sort(brakes also)
what should i look for and will it be expensive.

 

It has a power steering pump that runs off the fan belt just like any other vehicle. there is also a vacuum pump running off the same belt that provides boost for your power brake booster.
