I just got around to checking, because I bought 4 new wheels to mount my winter tyres. But in the tool area at the rear was a small plastic bag with one locking wheel nut socket. The one locking wheel nut is on the spare. The little instruction sheet seems to say that there should have been 5 ? This is a European CRD model 18" standard alloys. How many locking nuts did your 2016 Unlimited have? one or Five? Have I been cheated somewhere along the line? did I have 5 and 2 sockets? and somewhere along the line a mechanic took the 4 from the road wheels? and one of the sockets ? (so why didn,t he also take the one from the spare?) Just puzzling.
