Best Alignment Spec ?

[wraptor]

I have read all the threads and there seems be some differences in the best specification to set the front alignment at. Any real world info would help.
The computer read out was lost from the dealer. My truck is pulling to the
left, and has no on center feel. I also looked at the toe adjustment and left side (drivers) has about 3-4 more adjustment threads showing, should both sides be even?

Take a look at this post:

Here is what I asked for (advised and approved by Pirate Air):
Caster:
+4.0 to +4.3
Camber
-0.3 to -0.2
Total toe
+0.2 to +0.25

Kaiser, would these speck still apply when using a 3.0 shock and Aftermarket UCA? Also if I was to change tire size to 37"s would I need different specks or realignment?

I would think it would still be valid for all of these. It is always a good idea to get an alignment when you get new tires.

Note: If I recall correctly, if you are at the top perch, you might not be able to hit these specs as you might run out of adjustment. Maybe something to look at when the ride height of the 3.0s is set.

Note on UCAs: some may have different geometry from stock. Usually it will help with alignment, but something to look into.

Did you get you alignment fixed? If so did it fix the issue? I have the same problem with no on center feel.

Increasing caster will give greater straight line stability and also better return of the steering wheel back to center after a turn. If it feels floaty going down the road or touchy to slight steering wheel inputs its probably toed out a bit.

Had my truck aligned to the EXACT numbers Kaiser & Pirate Air listed above, steers on center and drives PERFECT!!!! No road crown added and does not pull in any direction.
One other thing is the mechanic had a person sit in the front seat to simulate a drivers weight. It made a difference in the settings. I am at mid-perch also. The threads on the tie rod end are still not equal but closer than they were.
Thank's again guy's for the correct specs!
