The transfer case drop only affects the rear drive shaft.
You are working on the front axle to DC angles, correct?
Correct, you know I think before anything drop or shop alignment, etc.. I might go get my tires checked after all. Flipping them and whatever so far done, caster, etc.. I might still be having vibrations because of my tires.
Also for everyone else, visually the driveshaft, pinion, yoke, etc.. angles look good up front and since I put 33s, I forgot that I'm about going 3-5 miles faster then my speedo shows, so I'd say the vibes start at about 50-55. Going 60 is perfect, going 40-45 is perfect too.
Now for caster, I went from 7.7, to 7, 6, to 5 and didn't do a thing, still getting vibrations, little less probably between 5-6 degrees of caster but the axle is facing upwords more then the shaft, if I visually look at it. If I align those visually and per digital angle finder then the caster is back at 7/8. So starting to loose my mind with all of this.
That said, having issues with my digital angle finder. I've recalibrated it multiple times and still its a PITA to figure out the numbers. Specially if I put it on the C bottom area I get all kinds of readout, if I push it agains the nut for the ball joint its 6 for example, but if I move it away from it, I get weird numbers, even like 3... PITA all I gotta say. Didn't have that much trouble with 3" lift and 1.5" body lift then I'm having with a 2" lol.. and same tires.
