u must know the whole under Carriage and what to look for for each part. Such as properly mounted, all hardware present and tight. Different things for different parts of the under carriage. Also must know engine parts, Hydraulic compartment & Coolant Surge System. It sounds like a lot but Once u see it and study it’s easy.
My road test is Friday
