Default Rear shock tower?

Hey guys, while changing my fuel filler neck yesterday I noticed a hole in the shock tower (~2"x4").. the rest of the car is rustless so I think I'd try to replace both rear shock towers..

But I'm wondering how to proceed and what would be the easiest to do it.. Go to a pick and pull and grab some shock towers from a donor car, or make some with tubing and sheetmetal?

Anybody ever done it or have suggestions?

Can a patch be welded in?

Can you get some pictures? Seems like a patch might work.

I don't have a picture on hand.. but I think I figured it out.. I'll have to cut the inside part of the shock tower to access the hole, remove all the rust, weld a patch and reweld another patch to close the hole I did...

It's gonna be a fun project thats for sure...

there is many layers to the rear shock towers. it would be a ton of work to get it fixed with new towers. You could easily patch it but it will eventually return. I drove my car around with that kind of damage for a number of years before I decided to scrap the car and get a new one. Mine had random spots of rust all over the place though and wasn't worth saving.

The rust holes i had were also quite a bit bigger than that.

You're the first person i've seen that has this issue besides myself. I think it is more common than most people realize but being that it is hard to see nobody knows about it.

it's not in a visible place, I never looked there before because it is so unusual to see rust there.. I noticed it because of the paint was peeling.. at the moment I put my hand on it, It went threw.... I'll see what I can do with it.

I would check it real close. Rusted rear strut towers are common here and anywhere there is a lot of road salt. I've seen multiple subarus where the whole strut tower separated from the body. A few were wagons and the whole tower with strut attached were just floating in the hatch area.

I would patch it and reinforce the rear strut towers like this

Honestly I would scrap that car. That is bad and in a critical area. It's not like it's a little fender rot.

Once you've seen these things blow a strut and tower into the interior you get real leery of rust that bad.

As sir Charles Barkley would say. That's turrible. I've done a bunch of various rust repair. If someone was paying me to fix it but if it was my own no thanks. That's going to be a lot of work.

looking at it, the fix shouldn't be too hard, just time consuming. i have been doing a lot of rust repair on a old 71 chevy vega and you just take one panel at a time. make sure to get some weld through primer and some sheet metal tools and it will make it easier.

I'm in the same situation with an SF Forester I just bought a couple days ago. I gutted the interior to replace the filthy carpet and carpeted trunk parts.



The black thing is the gas filler. The hole leads outside and the rust in the previous pic is just above it but out of view.



I have no welding experience but plan to get a cheap MIG welder tomorrow. I measured the steel to be 22ga which I hear might be difficult to weld.

Have you made any progress?

Would using thicker steel make for an easier time welding? Does 22ga sound right? maybe I got a bad reading for the digital caliper.

welding sheetmetal is going to be tough with a cheap welder and with no experience. welding 22ga sucks too welding sheet to thicker sheet is easier as you can put more heat into the thicker stuff, but still, its going to be a bitch.

okay so, I didn't take a lot of picture cause I was in a hurry to put it back together.. but i cutted all the rotted metal, grind the rest that had only light rust on it, afterward I used a mig welder with gas, to "spotweld" it, (i used 22ga sheetmetal) wen everything cooled down I removed the mess it created(dust etc etc) Used JBweld to cover the spots I didn't spotweld. let it dry..

And used a bodypanel sealant over everything to prevent rust. And sprayed gravelguard over both shocktowers so humidity stays away (at least from the inside)
