Broken TAM attachment

[04quadcoupe]

I noticed my new wagon had a bad motor mount when I bought it. No biggie, ordered new ones from rockauto, be here Monday,...

Pulled the air box off last night and found this:

The attached point on the frame is toast. I'm sure I'm not the first person to run into this, whats the most economical way to fix it?

Wholy rust batman! Did the captive nut pull out of the frame?

Unfortunately, yeah. The worst part is that the rust isn't even that bad. There's some paint bubbles and surface rust, but nothing structural except right there at the mount.

From looking at it, it looks more like a stress fracture that split more than rust damage, the lines are pretty straight and match up evenly, and everything around it is solid.

So it pulled the nut right out of frame?

Yes, I don't think it was completely attached to begin with, but it pulled through.

drill out spot welds and weld in a new bracket, unfortunately

also, move somewhere with less salt

I just moved back up here from SC lol.

That's the route I'll go eventually. For right now I'm going to engineer something to get me by for a few months until summer when I have more time to play with it

If you have a welder, thats probably a quicker repair than trying to come up with an alternative.

On early cars that mounted to the subframe instead of the frame rail. You could also try stealing and welding in one of those.

I got lucky and found a bolt on my workbench that had the same diameter and thread pattern, and was about an inch longer. I used the broken piece of the mount as a spacer, went through the original hole in the frame and secured it with a big washer and a nut. It's not ideal, but it should hold for now. Next week I'm borrowing a welder from a buddy and I'm going to weld a brace on to the subframe that will go between the head of the bolt and the TAM and sturdy it up a little.

Once I get the rest of the major annoyances repaired and have more time on my hands I'll do it right and either swap the subframe or drill out the spot welds and weld in a whole new bracket.

Well, my quick fix lasted a whole 40 miles or so. I remembered I have some 1/8 steel L-channel laying around, so I think this week I'm going to replace the top trans mount and fab up a new bracket for the dog bone and weld it to the subframe.
