Snapped bolts in subframe dog bone mount

[turbomick]

Arite guys had a bash at doing the powerflex dog bone mount and. The heads off the bolts to the sub frame snapped off and the mount still won't come off the sub frame. Has this happened to any of u guys

The mount is till stuck on solid lol it's ASif the mount it's self is threaded. Thinking of abit of heat and good old mole grips

The mount isnt threaded! The bolt has corroded onto the dogbone mount

This happened to me!
You have to smash the existing mount off. Then get a set of grips onto the remaining threads and get them out

Heres my mount and snapped bolts

Spot on mate just wat I was thinking did u use heat

 

[BigJase88]

No i used a hammer and a chisel!

And loads of penetrating fluid!

Took a good hour to smash the old mount off as it was seized solid! Held on until the end!

Then the remaining bolt threads came out with a set of grips

Got a 2nd hand mount off an octavia vrs and fitted powerflex bushes!
Mega difference

Lol I dremmeled the sides off my mount to get the stupid thing off then the bolts were like finger tight. I got a couple of new bolts from dave seres and smothered them in copper grease this time.

 

[BigJase88]

I used stainless marine grade m8 bolts. That way they wont be rusting on again. A bolt is a bolt


If only i had a dremel

 

[Seatmann]

It's not the bolts rusting that's the problem though, it's the alloy and steel together causing a reaction and when the alloy corrodes it forms a lot of build up which seizes the bolts.

 

[BigJase88]

Ah right. Whats ali and stainless like?

I copper slipped the fluff out of it

 

[BigJase88]

Just been googling

Its known as galvanic corrosion

Lol

I'm doing mine soon,been soaking it in "Shock & Unlock" from Halfords,stuff is really good,much better than WD etc.
I just Aero'd my front wiper arms,they took 3 days soaked and the proper removal tool & still a bitch to move,copper greased the splines before fitting new ones.

Sorted it lads grided the old mount off and the snapped bolts was just finger tite.
Replace with a second hand mount and new yellow power flex bush and what a diffrence it's so much better bit more vibration throw wheel on idle but should bed in

My powerflex mount arrived yesterday

Glad I haven't started this job until I order new bolts on Monday.


Nonetheless its not one I'm looking forward to. Who reckons I'll need a new mount complete?

 

[BigJase88]

Replace the front bush too!

Doesnt add any vibes really but make a nice difference
