Broke a subframe bolt

[IVVVIKris]

I was installing the CTS rigid collar kit and a 16mm subframe bolt (the last bolt needing to be torqued down) broke while tightening it. I hadn't removed the bolt completely, only back it out a few turns, so it wasn't cross threaded. Something snapped and the bolt head continued to turn. I can't get it to tighten or back out. It's the rear, right 16mm bolt in the center of this photo.

What component above the subframe does this bolt go to. Any tips for extracting that bolt?

No idea what it threads into goes but you're going to need to drop the subframe to investigate. Hopefully it snapped close to the head of the bolt so you can get something on the remnance to spin it out

The 16mm bolts are for your steering rack.

I just found some front sway bar installation instructions from Hotchkis. That bolt is the only bolt holding the steering rack to the subframe on the passenger side.

Man, I was worried about that. Anyone ever COMPLETELY drop the subframe? I have access to a lift. Just nervous about messing up anything else.

Always use a torque wrench to tighten with the correct lbs.

It will be fine just drop the subframe

Thanks, I did use my torque wrench and I had the torque values from HYDE's install and from the Tyrolsport instructions.

Take the subframe apart to inspect.

I'll be doing that once I get a replacement bolt from the dealership.

The bushing that bolt threads into broke loose and spins with the bolt. I'll likely have to drill the bolt out.

If you cant drop that screw the steering rack will hold up your sub frame from dropping because the steering linkage is limited. Take a grinder to the head and grind it off and it should push through.

Worse case nut and bolt the rack after. A grinder may be your best option. If you grind off the head you may not have to drop the sub frame.

Anyone know the part number for the bolts that attach the steering rack to the subframe(s)?
