TJ Frame Repair

I have a 2000 TJ with frame rot on the side of the frame where the rear suspension arm mounts. I see there are repair kits for older jeeps to repair the frame. Does anyone know of a repair kit or a method of repair for this?

I had the same problem. I cut the bad frame sections out and welded in good sections from a frame that had been damaged in other areas.

It's a lot more work but I've seen a lot of TJ frames for sale from $200 - $400

It would give you a chance to POR15 the frame.

ROT or just RUST? Surface rust can be wire wheeled with an angle grinder and then painted or treated with POR15, Rustconvertor, or just oil.

I've never seen a frame repair. I always thought that if the frames busted or cracked then that's it. Done.
Got any pics of said repair? I'd like to learn more.

To the insurance company if a frame is damaged they total it, but you can fix any frame, but if it's real bad it's not worth all time time.

A lot of race cars have the rear of there frames cut off and have tube frames welded in so they can fit larger tires and setup a 4 link suspension.

Older Chevy trucks had a problem with there frames where the steering box bolted to the frame when they had big tires, so they made a thick piece of metal to add material to the frame.

Some motor swaps take up more room and the frame needs to be notched. You cut out a piece of the frame and weld in a new piece.

There's a lot of work that can be done to frames, if you google it you will come up with tons of pictures.

I don't have photos but, what I did was, welded up a brace that spanned the rotted section and welded it to the frame. I then cut the bad section completely away (through the entire frame). This section included the rear control arm mounts. I then cut the 'new' sections to fit, beveled the edges for a full thickness weld then ground the welds flat where needed to apply reinforcing plates that I stitch welded in place.

I did both sides in the rear and replaced about 16 inches of the front of the frame over the course of a weekend.

This was done several years ago and there are no signs of problems after many off road excursions and a lot of winching.

What welding rod type/designation did you use?

Thanks, Stan

Incorrect. We have to go by what the mfg's say. If the mfg has a sectioning procedure (cutting and replacing the damaged areas) then we go by what the mfg says is a viable repair. Frame damage has no bearing in weather a vehicle is totaled or not, only the cost of repairing the vehicle determines if it is a total or not. And where I work its if the estimate is more then 75% what the vehicle is worth. I've sectioned frames, replaced uni-body rails, replaced frames ect... with out totaling a car.

And yes if you have the skills sectioning the bad portion is good repair. Or even replacing the frame is a good repair.
