Title: Broken sway bar bolt
Post by: Rummy on June 10, 2012, 01:17:57 PM
G'day Forum,

PROBLEM: I have broken off one of the bolts that hold the sway bar in place & it sheared off inside the sub frame.Whilst trying to drill bolt out i have pushed remaining bolt & nut inside the sub frame & am now at a loss of how to fix this PROBLEM!!!

QUESTION:Do i now have to cut a hole in sub frame to retrieve & remove this lost piece? If so where's the best place to do so?

Thanks Rummy.

Yes you will unfortunately - from memory the thread is actually cut into a larger piece of metal which forms the slot where the other end of the mount goes in. Rust inside the subframe eats away at it and broken bolts are common. I would cut into the bottom of the subframe around the entire mount area and repair the whole piece, then weld it back in.

Thanks Ken for your quick responce, I had my fingers crossed their may have been another way as i have had no dealings with the internals of a sub frame.
Anyhow gives me another reason to TINKER!
The learning continues!
thanks again,the wealth of knowledge on this forum is excellent!!

The problem with a nutsert is that what has been pushed into the subframe is part of the structure of the mount. The plate inside the subframe is about 25 x 50 mm and provides support for both the front and rear part of the sway bar mount - if it is that badly rusted that the whole thing bent upwards when drilled then this is a sign that there is more rust inside than meets the eye.

Yes it could be to rusty to fit a nutsert  but if it looks solid and you dont want to cut it apart and want to get it running again it could be a solution.

We fit them up to 12mm at work and they are extremelly solid

Look at 365days project he has fitted them to his front subframe to mount the guards.
i can send you some free of charge to try its just the guns worth 2500 dollars but you can fit them by using a bolt and washer to pull them in.

G'day Pete,
Thanks for the info on nutserts, this could be an option as the sub frame itself seems quite good.Half the cause of the problem probably came from using a centre punch & blunt drill bits! worth a try first. I'll have a look at sourcing nutserts from here as there is a good fastener shop in town.thanks for the offer & info.
Greg.
