CJ7 Frame Question

Hi all,

Its been a while since i've visited the site.......After owning my CJ for almost 20 years, i've gotten to the point of ripping her apart and rebuilding her. I almost have it fully down to the bare frame and I noticed something. It appears that there is a lot of welding slug on the top of the frame. I was wondering if that is something that is typical to see from the factory or has someone been in there before and did some repairs? I don't see anything that leads me to believe that the frame was damaged or rusted, but it just doesn't look quite right. What do you guys think???

I would expect something better from the factory.

Looks normal to me...I have three frames that are completely original and have similar weld crud in different spots.

Here is one with welds like yours in the same area...

The factory welds on CJ frames were never really good. Not uncommon for the front frame horns to come apart near the front cross member. Yours do not look like they will be an issue.

Thanks guys......I had a feeling like the weld mess was a factory thing, even though I would expect more from the factory as well. Its good to know that I am not the only owner that has this.

My frames have poor quality factory welding. even I could have done better.

Your frame looks quite good for its age. I would suggest an internal wax injection as well as an external paint. Glavanising is possible as a sacrificial coating but it is only really of value if you run in salt areas and even then it needs good preparation.

Jeepnstein,

If you are not familiar with cavity wax to prevent rust inside of various parts, like a frame, Google 3M's Cavity Wax Plus. Also check out their applicator wands.

Fluid Film is another option that's readily availabe at auto and farm stores, their website says it is made from "specially processed wool-wax, highly refined petroleum oils". I have been using it and it lasts for months and seems to perform well. I have not used the 3M product so I can't speak to which is better.

Thanks for the advice guys....I definitely plan on doing some sort of internal frame protection, I just haven't had a moment to do any research. It would have been a whole lot easier if the interior part of the frame would have been somewhat accessible.
