Rusted frame

Hi everyone I’m new on here.
I have an 04 double cab. It’s my first tundra.
I love the truck.
It rides great, it’s comfortable,
And the 4.7 is surprisingly powerful.
Today I found that there is a rust hole about the size of a quarter in the frame with a small crack about an inch long coming from it. Has anyone ever done any welding on their frame?
If so, what type of welding rod did you use. And if you have ever patched a frame, what type of material did you use?
Any advice would be appreciated.
Thanks!!

 

Not on a tundra but lots of welding on vehicles over the years.

I used normal 6011 or 6013 rod. Metal was whatever hot rolled mild steel I needed. Truck frames are really basic when it comes to metal and design. Tundra frames are just simple C channel. I would just weld some plate over it as needed. Just be careful not to burn through. The frames are fairly thin, which also means there is little point in using thick steel for the patch. Just something like 3/16th that is most of the width of the frame should be fine. Just make sure to clean everything to bare metal in the area and then paint afterwards.

 

Good information.
Thanks!!

 

Have you checked with the dealer to see if you truck is covered under the service bulletin/recall/extended warranty (what ever they're calling it)? They're still replacing frames around here. I was at the dealer last summer, and they had 40 new frames stacked like chord wood behind the dealership, waiting to be installed.
If I wanted to buy a muffler for my truck from the dealer, they'd have to order it. But they have 40 frames in stock, ready to go. Crazy!

 

I used 3/16 rolled plate steel with 6011 rods on my rusty tacoma frame.
