Frame Repair Ideas

Postby HeavyMetalThunder_81 » Sun Apr 29, 2018 1:11 pm

Found one of my front spring hangers loose. I've read that this is somewhat common and that the frame beneath is damaged. Well I ground and chisled the rivets off and found this:

Now my question is, how have you who have dealt with type of damage repaired it? Any real life experience or theory of repair information would be helpful. Thanks!

Was this jeep originally from back east? Never seen that kind of rust on a 76+ FSJ from out here.

As for fixing it, I would patch the whole in the bottom of the frame, and then weld on a new spring hanger. There are universal ones that will work fine for you. And then check the other side, it may be on its way.

Nope, been here in the Central Valley it's whole life. It sat in a field with all the windows down since '93

I do plan on doing both sides. Thanks!

The other tab stayed with the spring? Likely I would repair the frame, weld on a new hanger, and put a strap through the hanger that's stitch welded in the long axis of the frame.

I like Tim's idea.

I got to see one come apart in Moab once. This was on Shimniok's Troubled Child. He happened to have a new cordless drill with him and between the rest of us, we found enough bolts to go in the drilled rivet holes in order to get off the trail. The next morning he was at a welding shop and goterdun up proper.

Thanks, Flint. You wouldn't happen to have any after pics of the repair, would you?

I wish I did... You might get something from Shimniok if you PM him. He is pretty good at getting plenty pictures on outings.

Removed the passenger side mount yesterday afternoon. That sucker was ON THERE. I probably should have left it alone but I'll be reenforcing the frame in that area on both side now.

Anyone have a definitive answer to how thick our frames are? Some say 1/8", others say 3/16".

I would not be surprised if it is both depending on the year and how much money AMC felt like spending that month.

After recent events i believe the earlier ones were thinner sheetmetal than the body lol at least thats how it seems to me. I believe early was 1/8, newer were 3/16, but it varies it seems. The newer ones cohld be 1/8 if they were built at 5pm on a friday haha. The only thing i have found consistent with FSJ production is that nothing is consistent
