seam welding and rear suspension strengthening, What to do, What I did... Options

[Andyrew]

So my project for a stronger chassis has begun.

Heres were Im at right now. Took the suspension out today.

I'll go do some welding and prep tonight, hit the bed, see what you guys say, and do some more welding tomorrow.

Picture of some buckling of the suspension. Other side has a raised area, but is generally flat, this side has raised and concave area's. I'll be adding something here for strenthening, a tube? A flat piece of metal? A triangle?

Andyrew,
The blue tube in your sketch won't do anything
The part you are connecting it to isn't structural...

another area to put some thought in is were the framerail ends at the rear shock mount
with the firewall in place it's gonna be hard to weld the vertical part of it, but you can seem weld the top/horizontal part of framerail to the firewall and on the other side of the firewall, seem weld the shock tower

stichwelding the rest of the shock tower isn't a bad idea either

check brant's build thread, you'll find some good pics there (including how he managed to weld the vertical part of the framerail by cutting a section out of the firewall)

re: the rear susp bolts coming loose
maybe your the shoulders of your bushings are are too "high"
the trailing arm shaft should be slightly wider than the bushings to get a secure mount
