LJ front frame repair suggestions

Hello all,

Absolutely hate that I have to make this post asking for suggestions on my Jeep. Bought it about 2 years ago, Jeep LJ 160k 4.0 automatic. Runs great and drives pretty well. There’s a shitty lift kit that I’m planning on upgrading at some point as well as plenty of other stuff.

Unfortunately when I bought it 2 years ago I was still relatively new to the LJ game and I didn’t notice the obvious frame damage to the passenger side front section. Honestly I Probabaly never noticed because it still drives really well.

The damage is kinda odd, if people want to see I’ll post pictures if I can. right above the front lower control arm mount, basically in line with the upper control arm mount (where the big like 1.5 inch hole in the frame is) it’s vertically crinkled and there’s build up of weld from what looks like a shitty flux core welder on the bottom of the frame where I’m guessing the frame split a bit. If I go up the frame behind the spring mount there is another vertical crinkle on the inside of the frame. There is also more weld build up on the bottom of that crinkle as well. From the very front of the frame to the spot where the springs mount its perfectly straight. Everything is painted, no rust and seems to be functioning perfect, even the small amount of off roaring I’ve done hasn’t bothered any of it. The original front bumper has also been replaced and the front radiator mount has also been shittily welded back on where it looks like it has been broken off.

Here’s what I think happened, the previous owner hit something like a tree stump with the front right corner of the Jeep, below the fender and only hit the bumper. That crumpled the frame in those spots but did little damage anywhere else. Someone pulled the frame back to the correct length and tried to weld the splits of the frame and painted it. Any symptoms of the frame not being straight are not present. Jeep drives straight, none of the control arms looks out of place at all. Tie rods and steering all seem to be correct. If the frame didn’t have obvious repair I wouldn’t even know it was damaged.

Here’s where I need help. The frame is in immaculate shape other than this issue with almost 0 rust and anything else. I WANT to fix this and I’m capable of welding and other vehicle repair. I can get a frame repair kit for the lower part behind the axle but nobody makes a full front repair kit or anything of the like. With jeeps being a commodity, it’s hard to find damaged jeeps with the front in tact. I can’t afford to take the Jeep to a professional and spend thousands to have it repaired

How can I fix this issue myself?

Is anyone selling that section of frame? I can get 3/32 steel to box it with after butt welding the frame pieces?

I want to fix this before doing a bunch of suspension upgrades in the coming years.
 
We definitely need pictures. However, as a starter, there are pieces of the frame made. Take a look here:

Holy crap you guys are awesome, I just could not find anyone who made the front part that I need. I’ve attached the pictures. Let me know what you guys think.

So the link you sent has the parts for fixing the bottom portion of the frame and boxing the top portion but the crinkle as you can see above is right behind the spring. Any recommendations how I can fix that?

Looks like it's been repaired B4 or altered for some reason. those don't look like stock frame brackets. Any chance it took a front end side impact?

There is a section of frame by the spring/shock that is crushed . the shifted metal at the hole is the oddity.

According to the dealership, "never been in an accident" Never trust dealers guys.

The frame is all original as far as i know as there are no weld splices anywhere on the frame. Per the original post i believe it hit something on the front right just on the bumper which did the small amount of crumpling, they pulled it back straight and just welded it wherever they could and painted. I'm thinking the best way to repair this issue is to find a tj with a good front right corner and splice it in using "Rust repair boxing"
 
If it's strong and causes no issues you don't have to do anything.
im worried about it not being straight. The jeep drives fine and hasnt given me any issues yet but on the inside of the frame the upper control arm mount is definitely pushed into the frame, the frame is crumpled slightly behind the spring like you mentioned. Do you really think i should just not worry about it? Am i worrying too much? Im wanting to do upgrades to the suspension and if theres a reasonable way to repair it i might prefer to do that before i sink thousands into a quality lift kit lol
 
The first thing I would do is take measurements. If I could find they didn't get enough length back to that side or it's rotting inside then i might take action.
 
any recommendations where i could take measurements from? I also dont have much to compare off of. If the frame is straight when i measure it i might just replace the upper control arm mount and do a small amount of boxing to reinforce those weaker sections where its slightly crinkled
 
That rail is fucked and if the dealer knew they screwed you over good..there is no safe or legal way to fix that damage..you either live with it or frame swap it..splicing is a possibility but must be done correctly and by someone experienced or don't bother
 
Maybe call your local body shops. Not for a repair just to get intel. One of our local shops specializes in frame straightening. They cuuld do the necessary frame measurements. Another idea is to take it to a tire shop to see if there is an alignment issue.
 
I'm pretty sure Motobilt has a front half frame kit, I'm not sure if it would come back far enough to get you to past the bends though.
I looked at that front half kit but unfortunately its specifically designed for people who want to stretch their wheelbase and dont have any mounts for shocks, control arms or engine mounts. Super custom
 
If the front bumper is level I don't see why you'd spend any time on this. If you are worried it is weak than just weld some reinforcements onto that section. I don't see why you'd replace any control arm mounts, at least not in the pictures you posted. Personally I might just get an alignment first to see if it's within spec. Keep in mind all the factory welds look "shitty" and none of the pictures you've posted look like they have bad welds.

I was thinking add some fish plates over the buckled area. I think the frame is designed to buckle there. It's not ideal but it happens. you can find replacement frames at wrecking yards or it's a good opportunity to cut it off and start going custom :). So long as you got an angle grinder and welder.

Ive got a lead on a TJ frame thats in pretty decent shape that the guy may let me cut the peice i need off of. If it looks good i may just take a sawzall and cut it a few inches big, cut my frame, cut the new one to size, butt weld the ends and then do frame caps to finish weld it with. Ill add some extra pictures that show more of the damage.

The only way I would do that is pull the whole frame, check it for diagonal true at a lot of corner to corner places and then cut the whole front section off, add back a TJ front section correctly and do some tolerable splices on the inner face of the frame. Stagger the inner braces so you don't wind up with a hard line around one spot.

But I'd also do it so you couldn't tell it was done without a bore scope but that's just me.
