Floor repair - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Slammed96 · 10-11-2018, 09:27 AM

I've been doing a lot of reading on replacing floors/rockers/cab corners on here lately and noticed that the vast majority of writeups involve having the cab off of the truck. Aside from the obvious ease of access and space, is there any disadvantages to doing these repairs with the cab on the frame? I'm limited on space, so it will be less hassle to leave the truck mostly assembled. I plan on going slow and doing one smaller section at a time so I don't have to worry as much about the cab flexing or tweaking.

Just depends on how much floor you need to repair, if its just outer area then no need. I pulled mine but only because I did a frame off.

Maybe check the front cab mount area carefully. If there is significant pitting on the curved bracket that covers the body mount bolt, then there may be damage to the inside of the floor brace within this area. It may be wise to lift the cab to repair in this case.

I'll give it a good once over before I begin. Truck has been from southern states it's whole life, so the rot isn't nearly as bad as many I've seen.

Regardless if you go slow, just make sure to put in bracing. It don't take a lot of movement to screw things up.

Even with the cab still bolted in place? I also plan on leaving one door hung and closed at a time while I work on the opposite side.

I think so. It's good insurance. There may be others that would say no. I say better safe than sorry.

Fair enough. Easier to remove a few braces than in tweak a cab lol.

Yes sir!

I wouldn't bother with bracing, unless you removed the entire floor or roof.

Leave it on the frame and bolted down. Do one side at a time. This is how i did mine, no braces and i replaced inner and outer rockers and bottom of pillars and rear door frame bottom. I had all door measurements of door openings to make sure nothing moved. A little bracing hurt though.
