Fronts driveshafts are much tougher to keep vibes down on lifted trucks unless you change the caster angles by cutting and turning the knuckles! A common solution for wagons especially is running a CV joint at the t-case. 4* is not horribly bad unless it's a positive 4* (pinion high vrs low) Rear shims are iffy as they deal with constant torque loading. I suggest getting 4* shims and shimming the rear axle to get your planes parallel. If the vibes go away then plan on repairing the problem by relocating the spring pads on the axle by the same * that it took to smooth it out. Rotational vibrations are caused from inconsistencies. Example....T-case flange is -4*(down) tilt pinion flange is +4*tilt drive shaft is at 4* angle....-4 + +4 cancel each other out, driveshaft has no imbalance....no vibration. T-case 0*, Pinion +4* drive shaft at 4* angle....4's again cancel each other but the O* pinion has no way to cancel so you have a balance inconsistency = vibration.....solution - add CV joint which cases two joints to each take 2* of angle....4's cancel each other out again. Clear as mud?
