Are there any online how to articles with pics on replacing frame rails ??? I’ve been hearing a lot about rusty framerails and was wondering what the procedure for replacing them is.
Cutting out out rusted metal.
Creating new patch the way you want. It can be done several ways.
Prep frame rail and piece to be welded.
Weld.
Paint.
It’s also a grand idea to remove the paint and carpet on the inside of the same area…
Need to disconnect the battery. If you can, disconnect the ECU for good measure. If the welder isn’t grounded properly is can start arcing in unwanted places. So make sure you ground connection is good.
