Changing a rear subframe is quicker than redoing x4 bolts? Dear God Paul, please tell me you're kidding right?
And chucking a whole subframe away because of loose anti roll bar shims. The only real unknown here are
the actual bolts and the threads in the arms.
The Xm rear arms aren't
that difficult - honestly. You'll truly hate working on a CX estate if you're
worried about all these stories about sheared bolts and rusted solid spheres etc. The clearances on the
estate sphere are microscopic!! There is no nut in the arm, the thread for the rear bar bolts is chunky
enough in the alloy arm - the trick is getting the alignment of the bar right with the arm so the bolts
won't cross thread upon rebolting it all together. I do not kid you, to renew the shims would take a hour.
I was as daunted about the XUD bottom bolt you advised me on as you sound with this job and when I
tackled it with the right attitude (an tools) it was a doddle and the car was dragged back into life.
