Frame Crack

Hey guys, Happy Friday. Anyway on my 95 YJ i am starting to find frame cracks. I was thinking about just welding metal to and around it. I do not know if that is a good idea or not. Or if there are better ideas. Any ideas or suggestions would really help me out.

Those frame cracks might be appearing because the frame is thinned out from internal rust. I would eliminate that possibility first.

Do you know what was good about the good old days? I wasn't good, And I wasn't old!

Senators and Congressman should wear uniforms like NASCAR drivers so we could identify their corporate sponsors....

Grind the crack a bit to create a groove so you can get good penetration. You will need access to both sides of the crack to weld it completely.

You first need to rule out major rust problems, since no repair will last if you don't have solid metal to weld to as laybackman stated. Once you have ruled this out how many cracks are there? If it is just 1 or 2 you can repair them, but if you have several cracks, especially if they are different areas of the frame you could have serious metal fatigue problems and you would likely constantly repairing cracks. If you either have bad rust or lots of cracks the best option is to replace the frame if you plan on keeping the Jeep or sell/replace the Jeep. If you only have 1 or 2 cracks and no major rust issues drill holes at either end of the crack to prevent spreading, grind the crack as thantos858 stated, weld it, then weld on gussets (plates) to strengthen the area.

On my old CJ2A I had a bad crack that we did the above to and in addition we "fish plated" the outside - that is a flat plat with some 1/2" holes drilled through it - that we welded and plug welded on...never had another problem.
