33 /12.50/15 new goodyear duratracs 28 psi forgot to put that in post

 

any fixes to remedy this?

 

Just put my toe 1/8 inch in was 1/8 inch out what a difference not perfect but much better next putting stock pitman arm on see what happens

 

In my experience with 32 inch general grabbers, when I run lower psi, the ride is softer but I get worse handling and worse gas mileage. I keep them at 33psi and that's about perfect

 

Replacement is the only way. Some would say the steering box can be adjusted but this is risky and ineffective.

 

Pinion angle or caster wich is more important or is a happy medium what i want?

 

Caster affects your steering. Specifically the steering's ability to recover or self-centre after a turn, steering effort, and directional stability.

Pinion angle affects front driveline vibration.

In very extreme cases the solution is to clock the diff housing relative the the axle Cs in order to reduce pinion angle while maintaining caster.

However with your specs you should be fine with the general rule of thumb which is to sacrifice only as much caster as needed in order to eliminate front driveline vibration.
