The four bolts that hold the front subframe to the chassis (part Nos. 3 in the link below) are thay re-useable or are they stretch bolts?

Im pretty sure they are re-useable but just wanted to check.

Well i was told they are stretch bolts
there is a way to test them but it means buying some to waste.

I would just get new ones for the sake of Ԛ£4

When fitting the new/used ones grease up the caps.

Whats the torque setting for the subframe bolts?

A good mornings work and the subframe has been changed :cool:
Had a bit of a fight with one of the bottom ball joints, but other than that it was pretty easy. All thats left to do is refit the wishbones to the struts and then tighten stuff up 8)
