XZN / spline attachment 8 mm with 3/8 inch connection.
For all models with independent rear suspension (IRS).

Original CV joints only use bolts with an XZN head (12-point, also called polygonal), but if these have ever been replaced, it is possible that 8 mm hex bolts were used.

The socket has a 3/8 connection.
