4x4 cracked frame ???'s
How do you fix the crack in the frame!!!
I looked at the '70 swb K-10 350/465/205(I'm planning to purchase) a little closer today and notice that it has "the" cracked frame thing going on in front of the steering box. It is cracked across the bottom and about 1 1/2" up the side of the frame. This being the major flaw what would be the best remedy for fixing it? I've got a couple of box braces that I've saved for future projects I could put on it. Pretty neat truck, it even has the cab roof lights factory(hockey pucks) and the sought after tow hook option; missing of course but I'm contacting previous owners. Btw, it is a short step with wood bed and comes with a lwb parts truck. Please let me know your opinions of fixing the crack in the frame. thanks, Matthew ![]()

Mat, the alloy used for our frames is not real difficult to deal with. I would weld up the cracks making sure they are exactly on. then I would reinforce them with plate and/or box it in. It will probably last another 30 years with no problem.
Funny this was a common problem on chev's going back to the 58 Chev Impala. Mine had stress cracks where the box bolted onto the frame--talk about front end wabble!!!! ![]() |

me too
I looked at one that sounds alot the same but it was a 72 I believe. it was also cracked infront and behind the steering box these 2 locations had been welded (poorly) I got away from that one. It was pretty high for what it was.
I agree with Huck they can be fixed and many have done it. good luck

Thanks for the info. I figured you could just weld and brace but wondered if I should try anything else. I'm not too worried as the guy only wants $650 for them and I'm pretty sure I can get him down to $500 so if all else fails I can part it out!

mat , just a few quick pointers here when repairing the frame , ive done this numerous times and a few good hints to remember ,if youre cracks are not clear around completley separating the frame , take a small drill bit and trace down the cracks and at the end of them drill a small hole at each end of the cack , be sure to touch the end of the crack with the hole you drill , this stops it dead in its tracks with no place to go,then take a grinder and grind a V groove in the crack to ensur good penetration , weld the groove shut then grind smooth , when i plated it i would use nothing smaller than 1/4 inch , "DO NOT WELD VERTICALLY " this will only create a new weak spot for the frame to crack , cut horizontle angle edges on youre plate and weld them horizontally , also it is nice to add a few 1/2 or 3/4 inch holes through the plate that line up on both sides of the crack , then plug weld thos holes shut once you have the plate tackeds in place , ,, best advice i can give ya , she wont go any where if you follow those steps , the truck will fall into a heap and that piece will still be solid as a rock

MAC 67-thanks for the details, it will help tremendously!!!
1969 GMC-I've got the names of 3 of the previous owners and have been able to only contact the last so far. It has a winch bumper on it and I figure the hooks got taken off when it was put on so maybe the fella just threw the hooks on a shelf in his garage(LOL, YEAH RIGHT) but it's worth a shot. Matthew I'll post some pics of it when I go get it.

if you are not worried about a perfect restoration, go to your local off road shop and ask them about a repair plate for this problem. you still need to weld up the existing cracks as described above but a little extra steel never hurt anyone right?

Congrats Mathew! You didn't tell me that you were buying one too! You've got that Sanford & Son syndrome almost as bad as me, LOL!

I kinda figured Jerry might reply, but I'll drop him an email.

Following the crack and drilling a hole is only for cast materials (cast iron). Just weld it up and be done with it. Some like to make a science out of the smallest things.
