On my MS6 I’ve been chasing a small clunk sound on driver side. Happens on sudden braking and acceleration. Went and checked the subframe bolts on that side. One was not quite tight and the other, well upon tightening it just ended up pulling threads out. I can thread it back in, but cannot tighten it.
My question is, what’s everyone’s opinion on best way to fix this. A few options, drill out and tap to m14, use timesert, use a helicoil, or lastly and most invasive, cut small hole and put a bit on backside of the bolt.
I’m sort of leaning toward drilling out and tap to M14 personally. I’m a little concerned that timesert or helicoil may not work as well as I suspect.
