Replacing the alternator on the Workhorse W22 chassis. Cartman provided helpful moral support.Much of the work is done from the passenger side wheel well...a pretty spacious work area, but mounting the alternator involved holding it above your head and inserting the bolts without being able to really see what you were doing. Not fun, but the job can be done yourself faster than the time it takes to find and drive to a mechanic. Plus save a couple hundred bills, too.
While you are in there, replace the spark plug wires with really good ceramic wire sets. Until we installed the ceramic plug wires, we were replacing the OEM versions every 10k miles (engine starts missing, plug wires arcing to the frame).
