Setting Toe-in, question? Bumpsteer problem.

[Psycho71]

Got the front end all rebuilt last weekend. I eyeballed the toe on it and was way off. I had it toe'd out, about 3/8",the thing walked all over the road and would follow the least little depression. Was a chore just to get it back home after a run down the street.

So today I got a bit more scientific about it. I picked up two 4' long straight edges from Home Depot, and bolted an "L" bracket to them so they'd bolt to a wheel stud. Took off the wheels, and bolted them up. Worked out really well, after I set them with a level so the measurements would be consistent.

So, I measured out from the centerline of the hub 17.5" (the radius of my 35" tires) and set the toe in at 1/8". I helped tremendously! But still didn't completely fix the problem.

How much toe-in is acceptable? I'm thinking of setting it at about a 1/4" and see if it gets any better. Don't want ti chewing tires up, but can't drive it while it tries to drive itself.

Also, the Burb has a slight lift, and the link from the pitman arm to the steering arm on the hub, has a slight angle to it. I know that it should be level or close to it. Just wondering if this is contributing to the bumpsteer I am experiencing. I'm not against a raised steering arm, but honestly, mine ain't that far out of whack. Not far enough for me to see how it could be an issue, but I've been wrong 2-3 times before So should it be completely level? Or is a slight amount of angle tolerable?

Oh yeah, no slack in the steering box or shaft, so the problem must be in the geometry somewhere.

Thanks for any advice.

'85 K20 burb. Unknown lift up front, 4"shackle flip on rear (sits about level now). 36x12.5x16.5 hummer take-offs on 9.75" wide wheels.
