Probably but you dont have to worry about that!
Its a straight forward job thats obvious to do when you're looking at it.
Basically remove the arb bush, then the bolt into the hib on the balljoint and then the 2 bolts onto the subframe, fitting is the reverse order.
What?!
Dont really understand teh question. The ARB=anti roll bar. The new wishbone will come with 2 bushes and the balljoint pre-fitted and thats it.
