As title my rear subframe mounting point (the one that attaches to the boot floor) bolt has snapped there's a few topics on here of people having the same Problem but no definitive answer as how to go about fixing it.

 

Don't wont to replace the subframe because its fine apart from this

 

Anyone have any ideas ?

You need to cut a hole in the sill, then heat and penetrating oil on the stud

It's not on the sill it the mounting point on the rear subframe itself

 

Where the rear trunnion mounts on to the boot floor

Drill it and tap it, 8mm or 5/16" unf or larger should suffice. Then use a screw and large washer to hold on the mounting rubbers. There is not much load on the nut that's missing anyway, it just retains the rubbers.

Tap the centre of the broken stub to take a screw, use what ever tap you have above 8 mm. Order one off Chronos if you don't have tap. assemble the mount with the original washer and the put a thick large diameter washer on the screw and tighten the screw into the mounting stub to hold the whole thing together.

Screws are fully threaded to the head, bolts have a plain section between the head and thread.
