I'm trying to do the simple job of removing a wheel on my wife's 2009 500 Multijet. Unfortunately for me this is when I found out the studs have all been over-tightened to the point only an impact gun would undo them. Unfortunately the locking nut key had sheared off!
I've ordered a new key but suspect that will also shear off, so I've looked online for a removal tool but they seem very limited in sizes. Most go up to 19mm, some up to 21.5 and a few up to 26mm. Can anyone tell if this refers to the standard stud head (and therefore 19mm should do it) or if it refers to the diameter of the locking nut head (in which case 19mm is too small) or tell me what size I need to buy?
