X2 on what UnlimitedLJ04 said about the root cause of that bent control bracket being those particular aftermarket control arms.
Not all aftermarket control arms are better than what the factory installed. Control arms need to be flexible enough to allow the axle to be able to freely move around. If the control arms aren't flexible enough, the invariable result will be either bent control arm brackets, or control arm brackets that are completely torn off where they were welded to the axle. Some control arms like Tera's first generation arms, ProComp, etc. are so inflexible that they commonly cause such problems.
To prevent this from happening again after getting the damaged control arm bracket straightened out, you really need to look at replacing them with different/more flexible control arms.
The below pic shows a good example of a bad/inflexible control arm design which is made by Teraflex. It looks flexible but it's not and it is well known to cause control arm brackets to bend or tear completely off the axle. I ran these exact arms many years ago and they tore my control arm brackets off twice before I figured out they were the cause. Notice it doesn't have a flex joint at either end, only stiff bushings.
The factory control arms get away with only bushings at both ends. How? The genius to the factory control arm design is that while it is strong in its fore-aft direction, it allows itself to flex/rotate around its longitudinal axis which allows the axle to move around without damaging its control arm mounts.
