V50 Diesel Estate 2011 Snapped Rear Strut Bolt Help Please!

[IainG]

Hi
Most of the thread lock used can be released with heat.
I sheared my drive shaft bolt when I tightened it up. I think the thread lock actually locked the bolt so when I did the extra number of degrees rotation the bolt snapped. I was only left with 5 mm protruding. I applied heat(with MAPP gas blow lamp) and it just came out easily with mole grips.
So with yours once you have drilled the centre of the sheared bolt, if you can get heat on it, it might come out easily with a stud extractor. There are many grades of thread lock ranging from anti vibration(quite weak) to high strength(can sheer the bolt high) but heat will weaken or release most types.

So I started to create something else, which I'll get back to, but it didn't work either, so in desperation I found a nice juicy six inch nail, to make a centre punch, sharpened it like a pencil, heated it to cherry red and quenched in water. Two angry blows later with a decent 4lb club hammer, I had a little dent, bang in the middle of the stuck, stud bolt.

A bit of very gentle drilling, inside the cone that the nail had made, just to get the 'bite' and hooray, I screamed the street down, and danced a little. Drilled about 12mm deep in total although I don't think I needed to in hindsight. 8mm would probably been enough. I the used a 3mm extractor tool, it came straight away.

This headache is over. Dear God I am happy, thanks again for the help along the way.

Kind regards,

great news its removed these bolts dont need to be very tight use a small quarter drive socket set with a small ratchet to tighten if using thread lock only use the blue one.

So here I am to get back to that idea and share back! It might come in handy for the faint hearted, like me, who don't rellish the idea of drilling blindly!

So, as I said, I made my own version of a 'centering aid'. But for the job above, quickly realised it was too big!

My rear strut mount broken stud was 'shallow in in the hole' so to speak. But I still think this is a fair idea for studs that have snapped, deep into the hole, where a standard centre punch might not fit, and/or, when, you are definitely unsighted where you land your drill bit.

I'm sorry that I don't know what the fastener is that I have used came from. I was thinking some old decking then I thought, some old furniture perhaps? My shed is full of junk. I just cannot remember. I'm sure the visual will help you get the gist of the idea.

Find a fastener with deep cupped top, bore through the centre 3mm, cut off cupped top, smooth and clean, hey presto! You have a centering tool/aid for deep snapped broken studs! It can be popped in and held with anything to hand, chewing gum, putty, blue tac, I dunno, make it up as you go. Drill speed slow to start and gentle pressure throughout.

Hope it helps someone,

Kind regards.

Looks very much like the fasteners Ikea supply for holding desks/furniture together.

yes course thread counter sunk chipboard screw but you can use any type of plastic /rubber /copper pipe. which will fit the hole./drill size.

I totally agree! This man's shed junk just didn't have to hand the stuff of dreams!:

Cheers everybody and thanks again. The motor is back out on the road where it should be, all nice new strut mounts, shocks, stoppers and oh I put in two new drop links on the antiroll bar as I noticed one had sheared off. Not all bad news is it?
