After a hiatus, I need an opinion...

I never left, but I had so much stuff going on that I had to effectively put the Pioneer on the back burner. Now I have my eyes set on it again. 

 

So to recap- I have to weld on new floor panels, inner and outer rockers, cab corners, and the cab supports. I already have the two floors cut out, but what being that the MJ is a unibody, I wonder what order I should go in putting these parts on? 

 

Basically, I wish to avoid stressing the frame or letting it stand without sufficient support, whatnot...

 

Thanks!

I only did the floor pans and frame caps on my truck, but I would think if you're spot/plug welding everything I wouldn't worry about residual stress in the frame. Unless you're using an industrial spot welder you're gonna be going a lot slower than the factory when welding. Meaning heat soak is gonna be a lot less of a factor.

 

I would worry more about warping the rocker panels and cab corners with heat since they're sheet metal. As long as you work slow (but weld quickly) and let things cool properly I wouldn't worry about it too much.

So should I do the rockers first or floor pans first? I get the heat concerns but I'm always trying to figure out what sequence would make the best sense too...

I would do the floors first. It’ll be a good refresher that very few people will ever see again.

seeing as some MJ are driving around with essentially no rockers or floors, I think you'll be ok either way.    but yeah, I'd probably start with the floors and move outward from there.

 

don't forget to seal up EVERY leak.  there are many.
