Mike, do you have a turbo damper on yours ? If not, it may be a worthwile investment, I think they are supposed to help with studs snapping, etc...

Can anyone explain why the std ford studs are ok ? I bought and fitted a set of stainless ones on my 4x4 and was just wondering if they were really worth the extra wonga.

Good luck with the rebuild mike, our 2wd is going to have the same treatment very soon.
