So, in doing my spring over, I am at the point where I need to cut and turn the knuckles but am a little undecided on what I should be setting the caster at. My 1984 factory toyota manual says the caster should be around 1 degree. I spoke with someone from Over the Hill and they said they set their caster at 4-5 degrees. With larger tires does a couple more dergees in caster help out in the steering? What is everyone else setting their caster to when they cut and turn? ???
What's the optimal caster? (1 Viewer)

W Harold turned mine, and they are set at 4 degrees. With my 35's, it steers straight, and true. I have not noticed any increased tire cupping. I rotate every 5K to keep it that way.
Before the cut and turn, I did have a bunch of wander in the front end....of course the worn TRE's might have had something to do with it also...
Good luck!

so "too much" caster would show up as increased wear on the outside edges of the tires.
is that correct?
is that correct?
i put mine at 3.5, i should know how it drives by the weekend!!, Cant wait!! i am running 235's due to high cost of spring over, but will have 35" tires soon
For most of the larger tires you will never notice the wear. These are rigs that are not typically principally street driven rigs.. the bigger the tire the harder it is to manhandle around. A bit extra caster is nice to keep ot going down the street in a straight line..
FYI:
in case someone was wondering why you don't just put a ton of caster on a vehicle....
the higher the caster degree the more steering effort is needed to turn. This is because the caster wants to make the vehicle go in a straight line. (which is why we like it
)
Anyway, for our purposes, with big tires, straight tracking is much more important than a little more effort in the turns
I just thought someone would like the info... it took me a while to get my head around everything. :
