Alignment specs

Any one have the Alignment spects for a 08 450 4x4?

With my 4 link the shop around here don't want to touch it and will not give up the spec.

Toe, Camber, Caster

I have added -3 degrees caster to get the truck to stay between the lines,

Took my digital level and found the front wheels are at a -.5 deg camber. I have the adjustable shims to fix just need the factory specs to work with as a starting point.

I figure Toe to be 1/8 to 1/4 inch toe in

Cheers

Wouldnt mind knowing myself.

Dont know the exact but I think Ive heard 3-5 degrees + caster.
Was your toe off before you added four link? I need to get mine checked as well since lifting and adding 4 link..

I got mine done and it looks like they took everything to zero. I will have to double check.

The Initial issue was the truck tracked great in a corner but in a straight line it was all over the place.

Steering box... Replaced
Drag link.... Replaced
Ball Joints ... replaced

Addred a Four link and Air bags and when I did so I cranked in 3 degrees of negitive Caster. WOW the truck runs fairly straight still wanders on a straight and flat road.

I have an upgraded Track bar to install this week ( Adjustable) with a upgraded joint at the frame (No rubber) thsi should help with some of the wander.

Shade tree measurements for Camber using a digital level 1 decimal place to the right, Zeroed the level on the axle tube. Next Placed on the left and then right wheels ( measured Vertical deflection) the wheels showed a negitive .7 and .5 measurement. While this doesn't sound like much, I remember from my racing days a half degree of camber did make a big difference. +3 to +5 sounds like a lot, any Ford Mechs on the forum can you confirm?

Toe, Toe did not change when I installed the four link did nto mess withthe tie rod at all during the installation. Plus my installation only gave me about a inch in lilft. If the Caster is set correctly you should not get any toe change.

I can see the camber specs being around 0 to -0.5, that makes sense, but the castor I recall should be around +3 to +5, which should track straight(er), mostly everything nowadays has positive caster. Not sure if one side would be slightly less to account for road crown or not.

I will post what tire discounted set mine to today or tomorrow. The truck tracks pretty good except on the highway it pulls just slightly to the left. So slight that I didn't think it was a big deal but I guess it is?
