FRAME REPLACEMENT

[steveimpala]

I have a 2004 GMC 1500 Crew Cab that I purchased new. For a 13 year old truck, it has low mileage ( 60K ). The truck body is in great shape, except near the cab corner / rockers where it has some minor blistering. I thought about trading it in on a new truck, but I'm still recovering from sticker shock lol... even a used, 1 year old truck was pushing the high $30k. The mechanics of the truck is excellent, the issue that I have is the frame.....is rusting,large scales of rust is flaking off. to the point that I'm concerned regarding the integrity of the frame itself... are there new or used frames available for replacement ? And can certain years interchange ?

 

 

Thanks

Buy a used frame and treat it with por15 before swapping. I have done many frame swaps and its not difficult just time consuming for someone that has never done one.

1999 - 2007 will fit.

You'd be hard pressed to find a body that out last the frame. I'd look real close to see how much metal you lost, frames are pretty thick and just rust proof the frame. Salvage yards are full of frames that body's are rusted off of.

Agree with Karnut. I doubt you can shove an awl through the frame anywhere. Treat it to preserve it. Lived in Michigan for years and never had a frame fail from the salt used on the roads.

I wouldn't worry about it for the most part. If you can actually punch through it I would be a little more concerned, but it doesn't sound too bad from your discription. I know a guy with a old Chevy truck that he took off the road due to a hole rusted in the frame. He still beats that truck up on his farm and 4 years later its not broke yet.

I'd grind all visible spots that you can get to, hit it with a metal brush wheel, and throw some chassis saver on it, the stuffs kinda expensive but you wont have to re do it for 3 years!

How do you figure out what body mount holes you have? Rpo code? I see the 143.5 wb

Sorry maybe off topic but can’t find an answer. Can you put a 2010 Chevy 2500 HD cab and frt clip onto a 2006 Chevy 3500 frame

Hey I see this was post a few years ago but I'm trying to swap my 1999 extended cab frame for a 03-04 frame is this possible 

[shakenfake]

Yes as long as it is an extended cab with the same bed size also needs to be the same size truck so 1500 or 2500

Don't think so, they run different suspension types up front and have different steering systems and track widths for starters.

clean well - use the por-15 system (cleaner, prep, product) and you are good to go

Well this seems to be an active chat on the topic. So I have an 08 Silverado LTZ extended cab 4wd from Michigan. Frame is heavily rusted and cracked. I've found a fairly clean 08 2wd extended cab frame. My question is are they interchangeable? I found a parts site that kinda says they are but does anyone know for sure?
