Slightly bent front lower control arm bracket w/pics

Took it wheelin today and in my post-wheelin inspection I found this. Now I could have done it today, however the part of the weld that broke is not shiney and looked to be painted over (as in its been there a while). The tweaked bracket may have happened today however, not sure.

Can I simply bend this bracket back to level and re-weld that one cracked weld? Is it safe to drive until then? The other side weld on the bracket is fine, and 75% of the weld on the broken side is still in tact. I'm more worried about it being bent.

Factory lower control are brackets are notoriously weak. Cut them off and buy a new pair from Blue Torch Fabricators. Blue Torch Fab
Blue Torch Fab - World Class Rock Crawlers :: Blue Torch Fab

You will be much happier and never have to worry about bending them.

The damage does not seem bad enough to go through the expensive process of having new mounts welded on. I'm more looking to repair what is there. It looks like it can just be bent and rewelded since its only 1/2" out of level.

You will only be making the metal that is already stressed and weakened..more weak.
But being that the damage isn't so great, you probably could get away with it. Next time it will bend easier though.

the stiff control arms you have are the cause of that problem. this is why people often recommend control arms with Currie Johnny Joints on both reduces the stress on the mounts. you can either replace both lower control arm mounts with something beefy, or attempt to straighten that bracket and box it in with some 3/16" steel. also, that atrocious drop track bar bracket needs to be removed, and the track bar mount should be reinforced with some 1/8" or 3/16" plate.

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.

When you have a choice, buy American.
