1st: Yes I searched...
2nd: I still have a question....
My question is about caster angle. I know how to adjust it with shims so it is not a measurement or installation question. it is more of a practial application question.
I have a 1981 BJ44 (same as the fj40 front end) with some wander. I installed Alcan 4" front springs and 4.5" rears. The truck essentially runs level. After install of the springs and a 2.5 degree shim (thick end forward), a little driving and light off road to break in the springs a little, I took it in for an alignment.
The results said I have -3 degree caster on both sides (at least my axle is straight!). So now I need to get new shims to make up the difference.
So here (finally) is my question... I was thinking that putting in an 8 degree shim would correct my isssue and bring me to around +2.5 degree caster (3+2.5 = -5.5 degree caster with no shim. Put in an 8 degree shim and +2.5!) Stock is +1 but I have read here that some recommend +2 and other people go higher than that!
I don't use the rig for much heavy wheeling, more on-road, fire road and expedition type wheeling. With this in mind, should I stick with +2.5 degree (which will end up around +1.5 to +2 degree with the slight lowering of the front end with the thickness of the shim) as a target from end caster?
What are you guys running?
Oh, and my setup will be 35x12.50x15s on 15x8 wheels. I have 33x10.5 right now. I don't know if it matters, but I have a h41 and 4.11 diffs with an h55 going in very soon.
Thanks all!
