hole in the sub-frame

[willem]

Hi there,

Today i wanted to bleed the brakes to check out why my brake warning light isn't going off. I started to jack the car up at the front driverside corner, and noticed that the subframe looked kinda soft when i was pumping up the jack. On closer inspection i found a hole in the frame, a welded patch and a frame that looks a little dented here and there.

Any ideas or opinions? i have enclosed a few pictures.

regards. Willem

Weld it up.. if the hole doesnt belong to anything.just dont grind it smooth.. so your not removing any metals off to the sides of the weld.. you have access to por 15?

here's the hole. I circled it with a red line. Is that safe to patch?

It depends on what the entire rail looks like. My 64 had mouse nests next to the K frame bolts. It was thin there and cracked. I cut it out and welded in a patch. No big deal. Now if the entire inside of the rail is all rusted that's another story. Get a $20 optical camera foe your phone and take a look inside.

Will do, i just ordered a camera actually.

One question though: Suppose i find a lot of rust inside the rail, what's the story then?

Cross that bridge if you come to it. I've been pounding on my 64 for 7 years. Yanks the wheels every pass. No issue with the repair.

But how does it work? Do i need to get a replacement rail somewhere, or get one off another oldtimer?
i mean, in case the thing is rotted out

I checked, but AMD doesnt have these. Are there other manifacturers like AMD that could one of these in their supply?

When I had to replace my shock towers/uca mounts, the chassis guy found the rust had spread to the frame rails. He fabricated some new ones, wasn't especially cheap, but is doable if your desperate. If you can get replacements it's obviously easier but overseas shipping costs killed it for me.

Check with moparmarks on this site if you do indeed have to replace the rail. He has some nice high desert metal.

Hi there,

I have made the pictures with the endoscope as dvw suggested. Below you can see what the inside of the rail looks like. As a comparison, i have also enclosed a picture i made inside the rail on the other side (that one looks ok i think).

What do you guys think we're looking at here? Is that green stuff rust, or old dirt, or maybe some old coating that let go?
