Hi
Just a heads up just bought a xf 2010 v6 diesel
Am in the process of checking it over have just replaced the locking wheel nuts with standard wheel nuts as the locking nuts were getting corroded rusty
Had to do the same on my Honda accord last year
and they were a bugger to get off have put on a photo of the offending nuts the xf. Is coming up to 10 years olds it's worth checking if your car is older also
Checked all remaining wheel nuts cleaned off and greased them and set to correct torque as I would not have been able to release them with the jag wheel brace all wheel nuts were over tightened
Hope this helps
