Hey guys, Just having some of the underbody corrosion fixed up for compliance and the exhaust, tailshaft, fuel tank and rear diff have been dropped to get into all the nooks and crannys. Can anyone think of any work I should be doing while this is all out? It took nearly all day to do (mainly because many bolts had surface rust and were hard to undo..) Thought about changing the diff oil, but read that servicing AYC diffs should only be done by the pros.. Is the AYC controlled by the gizmo in the very back right corner of the Legnum? (circled) Where the hydraulic lines run behind that cover? Putting it all back together tomorrow or Monday at the latest if I need to get any parts, suggestions would be most welcome!
