sub frame connector

[164runner]

going to install some global west sub frame connectors. seens like the rear sub frame the metal is not as thick as the front sub frame, just worried about burning threw rear sub frame when installing these connectors. anyone had problems with this? best way to weld? run a bead on sub frame then weld on top of first weld to connector?

I’d suggest you measure the metal, mock it up with scrap in the same working position and practice.
You can control which piece gets more heat by the position, speed, and technique.

I just went for it not knowing any better.  No issues either front or back, although I think the backs were easier and I wound up with nice beads there.

Here's right after the install, passenger side.  My beads sucked on the fronts, but they're solid enough:


And here's how the rear driver side came out (sorry for all the bondo dust - this was shortly after I got it back from the body shop):


I actually cut up a couple pieces of metal stock and welded on the ends of the brackets in the rear - there was a bit of a gap, so I closed 'em up to make sure no water would wind up standing in there (probably not necessary, but I did it just in case).

I always thought that was what they made grinders for. It's amazing how good some of my welds look after I've hit them with the grinder a time or two, and touched the welds up as necessary.

Yeah... well... they're under the car and nobody's ever going to see them.  That's my story, and I'm sticking to it.

Also be sure to remove the galvanizing where you are welding.

You can see I didn’t do a very good job of that where the plug welds are
