Dropped my K2xx at the shop on Monday to have them go through it. Nothing surprising at all; broken motor mount, exhaust manifold leak, play in control arms, needs struts and ball joints. Overall I was happy with the diagnosis.
ALSO–what a coincidence! This leveling kit I was already looking at knocks out like half the stuff on that list!
Pulled the trigger online from Rudy's Diesel this afternoon. Having this kit sent straight to the shop. I leave for Buenos Aires on Sunday (July 7). Truck should be ready to by the time I return, second week of August.
