murdamanche Posted January 3, 2019 Share Posted January 3, 2019 I am doing a full restoration of this truck, I have the bed off and all power washed ( old pic ) but I’m curious to know the weak spots as to where I should focus my welding the reinforcement.

91Pioneer Posted January 3, 2019 Share Posted January 3, 2019 Reinforce for what purpose? Rust holes? Additional cargo capacity? Link to comment Share on other sites More sharing options...

Taylor9995 Posted January 3, 2019 Share Posted January 3, 2019 I think a lot of owners agree that the floor boards can get pretty bad. I don't know to what extent the rust is on yours but mine just needs small sections cut and welded in, but it seems to be a common trend. Link to comment Share on other sites More sharing options...
DirtyComanche Posted January 3, 2019 Share Posted January 3, 2019 How bad is the rust INSIDE the frame there? Normally problems show up just in front or around the front spring hangers. The top channels by the bed mounts often go too from stuff sitting on them that's caught by the mounts. The box mounts will get thin over time too, take a look at them and see, they're probably still okay though. Under the cab it's generally because of rot through the floorboards, which then transfers to the frame below it. Also the LCA pockets can trap stuff and cause issues. Steering box area can crack, along with around the track bar bracket, normally this is a problem that was caused by massive abuse or other issues. Look for rust there too, as the metal is stressed it is more prone to corrosion. Otherwise I'd just look it all over. I've never actually seen an MJ frame fail from any sort of use that could be considered regular. The main thing if you're exposing it to salt is that you kill all the rust and get it sealed again properly. How you do that is up to your budget and willingness to deal with it. For something that bad I don't know what to say, other than getting the whole chassis dipped and coated. Edit, not sure if you meant just the frame for the bed area, or the whole thing, so I added some stuff. Link to comment Share on other sites More sharing options...

Thanks I had mine off for about a month. Just reinstalled yesterday. Shoulda took pics but I didn't have any rust on rear frame area and only minor rust on front of bed where floor meets forward wall where 3 drain openings are located. I used picks to dig the rust out very little perforated sheet metal (holes) hammered it flat again, sanded down forward wall and underneath the bed including wheel wells then Rhino liner. Also did the rear of the cab up to the top of the bed. I think it was 18 inches from bottom lip of cab to top of bed. About 4 inches below the back window. Used 2 coats, took about half gallon of Rhino linerSent from my LG-M210 using Tapatalk Link to comment Share on other sites More sharing options...
