I just went through this 6 months ago, w/33" tires it needs to be set at or around 5.5 degrees positive that will also help w/the pinion angle. 7 degrees positive plus or minus 1 degree is the stock specifications on castor... you'll see it will ride much better, not sure if your vibrations are caused by alignment issues unless you have DW but it's a start... good luck

Just keep in mind that pinion angle takes precedence over caster angle. 7 degrees is a bit high for 33" tires, lowering it a tad to 5.5 to no more than 6 degrees would be good and give you a better pinion angle. Basically the bigger the tire, the less caster angle you should run. Like 4.5 to 5 degrees is optimal for 35" tires.
