TJ frame rust

Hey guys I am looking at buying a 199 TJ with 78k with 4" lift hartop/softop and 33" BFG AT's for $4k.

The jeep has rust holes in the area circled in the picture (jeep in picture not actual jeep).

How concerned should i be with this area being rusted through? I know it needs to be repaired. Autorust.com has a kit for this area coming out in a few weeks. I spoke with them on the phone yesterday.

I am concerned that this area may be under more stress than the tail end of the frame that usually rusts out.

Converted to leaf springs? Hmm, is that what what you want?

Regarding the rust, better pictures would help.

It depends on how bad the rust is in that area. Rust is a common problem in that part of the frame - I believe the older TJs did not come with a drain hole there. About a year ago, I discovered rust there and drilled a drain hole in the bottom of the frame, above the control arm mount like others have done.

I've seen people weld on some flat patches to reinforce the frame there and then it's fine. If the rust is real bad and on mutliple sides of the frame, then you may have to replace a chunk of the frame with an angled, preformed patch.

If I understand correctly, the TJ your looking at has frame rust at the rear lower control arm mounts. This is the TJ spot. The rear frame doesn't rust out like the YJ's did. The spot you have circled is the location that TJ's seem to be rotting out.

I had this same issue. You can see my repair Here:

The pic is a TJ with modded rear end.

It was the best pic i could find online of the area. The rust is on both sides and I plan on buying the kit from Autorust.com. I talked tot he owner Dave yesterday, he said they are working on finalizing a kit for this area and should be available in a few weeks.

I don't have a pic of the area on the actual jeep. It is rusted through on both sides, the size is about 2-3" long by 1" high.

A little worse than than this:

Cut the rust segment out, weld in a new segment, and throw on some Chassis Saver!

I wouldn't even consider it. Period.
TJs are common as flies, find one that's not already rusted out.
