Whining Work Truck! Ford F550 PTO Pump Whine? Diagnostic drive time!

Some folks don't know this but we're actually a fully functional automotive shop, we don't just work on stuff or our fancy KZbin channel! It's way REALLY pays our bills and keeps our lights on, and today we're going some more real work on a staple of American small business, the work truck.
This is a 2022 Ford F550 with a PTO drive, and you'll quickly see and more importanly HEAR why it's with us here in the shop. A big portion of why we do what we do on here is to provide transparency on repairs and diagnostics, so that's exactly what you're seeing here. Let's go for a drive!
