94 yj Frame rust by rear shackle.

So i started hearing a squeak/creek from the rear end last week. After a quick inspection, i found the frame where the rear drivers side shackle bolts on is rusting out.

Hoping to get some advise on the proper way to repair this. Should i simply cut out the old rust and get one of the pre-cut frame re-enforcement kits I've seen around here? This seems like the easiest method to me, but i've never done frame repairs before, so im pretty clueless.

I know one of the POs of this particular rig already patched the rear frame on both sides, and it looks like he did a good job. The rust thats plaguing her now is a couple inches behind the patch job.

Heres a visual, let me know if you need a better pic.

Thanks
Jon.

*In the picture you can kind of see the other spot of rust. About the size of a quarter on the bottom of the frame.

The pre cut patches are a good solution but before doing anything I would inspect the remainder of the frame and perhaps consider a full swap.

I took a screwdriver to the rest of the frame, that rear corner is the only problem area i've come across. Everything else looks pretty sound.

I hope a full swap isnt necessary for such a small area.

This is what my passenger rear looked like. I opted for the Auto Rust Technicians pre-fabbed pieces. It is a common problem and most either opt for using the ART parts or cutting/piecing together their own. You can see what I did with mine beginning with post #4 in my build thread if you like. (too many pics to post here)

I had the same problem on mine, welded a 8 inch steel plate along each side, grinded the rust off and sealed some of the frame holes so water wouldnt pool in there anymore. Had the jeep balanced and aligned after that and now rides great
