Hi all,
I had a fight with my passenger side control arm rear bolt 200k miles in salty Canadian winters, I actually feel like I got off easy). The bolt snapped and was very seized in the bushing sleeve. To separate the subframe from the frame (and from the seized sleeve/bolt) I cut the subframe to get my cut off wheel in and cut the sleeve/bolt. It worked, but now I need to figure out what to do about the subframe. I think main options are (and I'm open to better ones!):
1. Mig weld the folded piece back in (recognizing that I'm a very novice welder and that steel is about the very top end of what my welder can do)
2. As above, plus weld a 1/8 plate over the area to reinforce it (I worry the extra thickness might through off steering/suspension geometry?)
3. Buy a (relatively) intact junkyard subframe (probably like C$120 or so)
I really want to do #1 or #2 but don't want to set myself up for a catastrophic failure.
Thanks for the feedback!

I had a fight with the rear control arm bolt, and needed to cut the subframe to cut the seize...
