As such, his gas tank has looooonnnng since surrendered, and he currently has a fuel cell in the cargo area.
Also why it looks like a clown car everytime he goes camping.

Troy's truck isn't really a truck. Its a collection of rust that has somehow, using magnetic fields I imagine, been molded into the shape of a truck.

Oh, and happy grinding Molly! Just remember that someday the feeling will come back to your arms/hands.

If you make the links parallel (the V pointing the same direction), the roll center height goes through the roof and you get a VERY tippy suspension setup. You can triangulate just one set (usually the uppers), but I needed to triangulate both to get the performance numbers I was looking for.
You need more than 40* triangulation to be able to not have a panhard bar.

So, the driver's side link and mount are pretty much trashed and will need to be repaired in some fashion. I don't see much reason to stay with the stock short links.
Would there be any problem with just replacing the lowers and leaving the uppers and panhard bar as-is for now?
I'm not liking the idea of the truck being down all summer reconstructing the rear suspension, and I can't really afford a shop to do it. What I'm thinking is:
- for now replace the forward link mount and the lower links
- later, redo the attachment points at the axle and the uppers, triangulated to get rid of the panhard bar.
Goals in the end:
- link mounts less likely to get hung up on
- more travel
- stretch wheelbase 1-2" towards rear

Just because I'm redoing the links doesn't mean I'm going to set it up for miles of travel. The current plan is to use the same springs (and possibly the same shocks) as I have now. Notice in the criteria list above, I never mentioned anything about lack of travel. It is for better control of the axle and less stuff to get hung up on.

Can't level the panhard rod to make the roll centre lower? I don't necessarily mean on your truck as you are triangulating the rear controls arms if I read correct.

Well, my truck is at stock height, so the suspension is as Toyota designed it.
Regardless, the axle shifts side-to-side if you have a Panhard bar. Might be only a little, but with my top-heavy POS, it's the last thing I need!

Are you using software for this?
I found a couple of links for 4 link calculator and Excel CAD that I then downloaded since I'm planning on doing a four link in the future, I could refind them if you want, or email the programs to you.

I want to triangulate my rear 4 link some day. My dream is to be able to run baja with it. LT front and rear suspension. should be interesting.
One idea for the lower links is to make almost like a mock radius arm in the sense that i would mount at the bottom and go upwards to give you more clearance.
Kinda like this idea, except more substantial since it is a major suspension component.

Man I wish the underside of Troy's rig was that clean! LOL. So I have de-rusted and am now doing the POR. I have the axle done and am doing the under-carriage now. Thank god for laquer thinner... I'd be perma black without that stuff!
A great grinder pic from yesterday! Weeeee!
