Hi all,
I have a yr2000 S-type, I needed to get the front wheels balanced the other day, the garage I used for years snapped the 2 lugs off on the locking wheel nut key trying to un do the locking wheel nut. I looked at the key and locker and to be honest it wasn't there fault its a poor design with only two contact points. ( seems the nuts have been over torqued by the previous owner/garage)
Any way got two new keys from Jaguar today just in case, went back to get the wheels off, First key sheared straight away using a wheel brace, they did not want to break the second key so manufactured a threaded socket wedged it on to the locking nut and got it off.
I have been back to Jaguar parts Dept and now bought new re designed locking nuts and key that have 4 locating points and a proper socket Cost £66 for a set of four.
So a bit of Advice if you have the old type still fitted that have the chrome cover cap over them I would strongly suggest getting them off and getting the new redesigned ones. It may save you allot of hassle on the hard shoulder of a motorway in the rain.
