Rusted rear frame trailing arm lower control arm repair

[Jhkj04]

Does anyone know the weld on or bolt on part number for replacing the rusted out frame around the trailing arm / lower rear control arm connection? My passenger side rusted out on a trail and we had to limp to a shop and weld some flat plate to get her home. Ended up alittle out of square with the axle so I’m upgrading to the iron rock adjustable lower control arms. It should be good for awhile but I want to prepare for a full
Repair and to get the driver side updated before it fails randomly. I see a post about this but no part numbers or details on can we use Jeep tj parts.

Looking at the corrosion around the underside of the Jeep that looks like only one of your problems! The rockers look like they are in need of attention too, they are a major part of the structural strength.
I don't think the mounting you need is available anymore, your will probably have to fabricate one or cut one out of a scrap car. The rocker outers are available but the inner steelwork isn't, I had new ones folded up by a sheet metal worker.

Yes she’s a camping and trail jeep, I cut the rockers out a couple years ago.

Wow ! That is a shame that KJ got so corroded.
Salt is so destructive

Sadly before it was left to me she lived in the Florida keys for a few years.

Needs a lot of steel welding back in to put the strength back in the shell, I wouldn't fancy riding round in that on or off road, crash it and it will fold up like a tin can, they aren't like the old ladder chassis Jeeps, the whole body is structural, the seat frames and belts need the box formed by the inner sills for strength.
There's nothing there that can't be fixed with a mig welder, some time and some steel.
