Bump steer?

Then for-go the mechanic, do it yourself & then get it confirmed for free from an alignment shop! Took me an hour.
Do it just like this:
1) Install SPC's set to neutral/ position D /2°
2) Adjust front cams all the way inward
3) Adjust rear cams all the way outward
4) Adjust camber, via ball joint, to ~0°
5) Adjust toe, via tie-rods, to ~0°
6) Drink a beer
DONE!

The biggest advantage to the SPC arms is the independent camber adjustment. The 3 position caster thing is kind of silly because everyone ends up in the middle anyway. That's why companies like JBA just offer one setting. SPC's explanation of how that adjustment works reads like a Chinese translation into English of a Turkish text . It confused the hell out of me at first, and I actually understand how this geometry works. Most of the alignment techs are just trained by the alignment equipment manufacturer on the operation of the machine. They can't deal with the SPC arms.

 

Why so high on the caster?

 

The taller the lift/tires, the higher the caster needs to be.

 

Ya. I don’t know why I asked that,,, but since I’m here,,, I bent the tab on the front driver side front cam adjustment. Will a spot weld behind that tab for strength be sufficient?

Or am I screwed?

 

I put cam tabs all back where they should be and laid a bead behind all of them. Total Chaos sells a larger cam tab kit but I think the welding does just as good as the kit.

 

Ok. Thanks.

 

Like MO said, bend them back & then lay a bead behind them. Problem solved!

 

So thanks to the OP and another bad alignment I’ve discovered steer bump. Yesterday I was looking at my tie rods and an epiphany. I’m going to flip them over to try see if I can compensate for my lift
Ingenuity or too much beer?

I’ll let y’all know

 

Keep us updated

 

Too much beer! The rod ends are tapered. You can't install the rod on top of the arm without some modification, like boring the hole and using a heim joint.

 

Oh well. It’s not the first time Sam Adams has taken me down the wrong road.
I kinda figured I’d run into something like that.

 

You know, sometimes "dumb ideas" are the perfect spark for great ideas. It would be great to be able to mount the steering rod on top. I'm not a fan of heim joints on daily drivers. A machine shop could bore that hole, and press in a tapered sleeve upside down. Then the stock arm could be used just as you described. Maybe someone with machining capability will offer that. It would be a very simple job for any qualified machinist. If we could just buy the sleeves, we could get the boring and pressing done anywhere.

 

I was going to research that heim joint but it seems that I can save my time. Kinda funny timing on this topic, but I’ll probably be trying to adjust my caster at Windrock because I’m now rubbing my cab mount.

 

If someome made some sort of tapered adapter kits for this they would make a killing for sure...

 

I’ll look into it more later. There’s some room left to suck the tie rod in a little. But first I have to address this. I bent it a little after putting my 3/4” spacer in. Toyota dealership finished it off. Letting me know there was a bigger would’ve been cool.

Not sure that this will be GSMTR compatible,,,, but I’m already here.
