How major a repair is replacing rusted frame cross members?

How major a repair is replacing rusted frame cross members?

Postby unflagging [OP] » Jul 01 2020, 1:31am

How common is this?
How many hours would a shop charge to replace the 2 main ones?
Seems like a huge repair

Just like the video shows....you never know until you start pulling things apart and find out the full extent of what is in need of repair or replacement. Anything you drag up to a shop and say please fix this....you going to get hit with a whopping bill. Both for exploration of what all is there and what is needed and for the actual replacement of parts and the repairs.

If this is on an older truck from the rust belt states...it is pretty common to see. Untreated frames up there just rot out.

I see in one of your others posts you're also looking for a replacement box. You're going to be chasing your tail on rust from this point on. Maybe it's time to find a different truck, maybe one from a southern state?

It's at minimum a full day repair in a good welding shop. You don't need the actual $200-ish crossmembers though, as they can use stock steel bar and weld it in place. I'm in the same boat, dealing with Northern truck rust.

Cost wise, if you supply the parts, and the shop will only charge for time.. That is based on what the shop charges, here in MA welders will get about $100/hr for shop time. 8 hour day, 10 hour day, whatever they work as a shift, etc...

OK, so $500 for parts, and $1000 for labor is a decent ballpark?
$1500 is not bad, could be worse.

You probably need to replace #3 as well, unless already inspected to look good. That being said, you can get the actual OEM part, which is stupid price, aftermarket I've seen as low as $250-$300, for each crossmember, being #2 and #3. Not sure what #1 is technically called, although it does similar to the other 2.

A good welder can probably just use some stock steel and weld that across, do the same thing, possibly cheaper.

But you can check LMC, Rock Auto, and for true OEM, GM Parts Direct.

This is one other place I looked at....more money, but probably better than anything a lot cheaper...

Re: How major a repair is replacing rusted frame cross membe

It turns out my friend who inspected the truck from underneath thinks only #1 needs to be replaced.
He said #2 looks ok, but just the shock mounts are rotted off.

So, the current plan may be to replace #1 with generic 1x1 box tube
And to just weld new shock mounts onto #2.

I wonder if this can be done without removing the bed ?

If the shock mounts rusted off, chances are there wont be enough material to weld to anymore by the time you get down to clean metal.

Re: How major a repair is replacing rusted frame cross membe

I'll agree with the shock mounts posing a problem potentially. I had my rear shock mounts replaced recently, and the shop told me there wasn't a lot of metal left, and they had to do some patch work that was ugly, but secure. Ugly not important as it's underneath, but there was no other way to make it work.

It can be done with the bed on, but the spare tire will be in the way. And even without spare, it's still very tight in that area, especially with the gas tank so close. Having the bed off allows the welder to go from above, which is much easier and how it would have been done at the factory.

I'm in the process of pricing out rocker panels and cab corners on my truck, and also planning to lift the bed off to check a few things and do some frame clean up.

If that pic above is your truck, I would highly recco cleaning up that frame and painting it...not so much for looks, but to save whatever metal is left. If that's not your truck...well, your probably looks like that anyway...lol
