It takes two

Thats never good.

You can tell it's old damage a fresh break would not been so rusted out.

is this salt or cacium damage from keeping roads bare from snow?

that looks like it was pretty aggressive if just water ....

It's where the frame had got damaged before and welded I think who ever welded it didn't do a good job and water was getting in. When I started taking it apart a lot of parts are used replacement they have dates marked on them and their are more signs of a front hit.

good you know your stuff and have the means and know how to fix it.

i'd get discouraged if i kept seeing wrecker parts as i went ....

After I got it all back togather on the frame I bought the plastics even fit better I thought they were a little buckled looking before and they were. I didn't know my stuff I learned as I went. I worked on cars for years so I know having an automotive repair background helped. The replacement frame was an almost complete quad minus wiring & plastic. So I took it apart first.

now thats a big hole in the frame

Thats where the A-arm mount should be.

That can't be good.

That could be a weak spot in the frame. Rust blows.
