Hi, 2008 G35x here. Just "finished" my first swap of sway bar bushings and brackets, which went well except for one thing. Naturally, with my luck, the final nut got over torqued and snapped the bolt off flush against the subframe. Is this bolt replaceable on it's own or would it involve a whole new subframe? If it is the latter then are there any known workarounds? My mood and finances are not really in the condition to replace the whole unit. Any insight/advice would be greatly appreciated.

 

Use a small drill bit and use a ez out it should pull it out. When using the ez out make sure to have it in the reversing direction and pulling the bolt out. Their is many videos online or people pulling bolts out that are flush in the engine. But if you aren’t able to take it out with the ez out you have been chance just using a drill bit and getting it out that way and retreading the hole. Go to a shop if anything majority of them will be able to take it out.

 

I believe its a stud on the subframe holding on the swaybar brackets...as Said mentioned drill it out, but you would skip the ez out part....once its drilled out you can put in a new stud with a nut on top or a bolt...I believe the subframe is too thin to tap threads into it for a stud alone so you may have to fish the bolt/nut through the subframe to get it through the hole...I don't know how accessible that is so if thats too tricky go to a shop and have the new stud welded on...in my experience, places like muffler shops will usually do this type of thing for a few bucks if they're not too busy cause most of their work is cutting and welding anyways and it just takes a few minutes but YMMV...good luck

 

Thanks for the tips. Car is heading to the shop tomorrow since the remainder of the stud is still in there and I do not have welding experience for a new one. Hopefully this goes as well as it has been made out to be!

Edit: The shop ended up being clueless on how to approach it and went the DIY route instead. The subframe is actually solid enough for tapping, which was determined when drilling out the old stud. Put a new bolt through with a touch of mild threadlock and everything seems back to normal. Hopefully I don't come back with any further updates!

 

I just did the same thing, bolt snapping is a common issue - z1 has a replacement that is stronger - $2.32 / bolt - https://www.z1motorsports.com/rear-s...lt-p-9149.html

also note - you can remove the rear sway by pulling it towards the back of the car (past the rear diff) and out behind one of the rear tires... Then install the aftermarket the same way,..
