CJ7 Frame Crack cure?

I have a 1986 Jeep CJ7 with some problems in the frame: both front end sides are cracked near the spring mount.
I tried to weld then but the crack appear again over the weld.

Does anybody know a "cure" for that or how to make a GOOD reinforcement there?

If you can send me any www where I can take a look in pictures or articles about that I will appreciate!

Thankx

Ok this time when you weld it take the stress of the weld area first. then grind a groove \ / looks like this on bothsides into the weld area. it should not crack unless the material itself is flawed. when welding this area make sure the slag from welding is gone by chipping with a hammer the area after you done welding. your looking for complete beads an no pitting in the weld if your still in doubt about the weld tack on a scab patch over the welded area

I already tried the "grove" process... but the crack re-opened!

Is that crack appears to a lot of CJ7īs frame or itīs just on mine?

Thankx
