I agree with everyone else that since you already sense you have a problem with pelvic rotation that is something you should investigate and try to address. However, what you describe also sounds to me like a classic case of simply having the bars too low for your flexibility and/or a bad saddle angle.
You did not mention what angle do you have that SMP at? After a lifetime of trying different saddles to solve problems not too different from what you describe, I am pretty confident you will not find anything better than that Drakkon, unless it is a different SMP. However, these saddles are very sensitive to the fore-aft angle you are using and a bad angle could cause what you are describing. Before you try a different saddle, it might be worth it to get an angle finder like this and place it on a board or cookie sheet or anything you have that will span the saddle from front to back. Then follow the great advice on Steve Hogg's SMP page to see if you can get a better angle. I hope your seatpost allows you to make fine adjustments to the saddle angle.
FYI, Amazon has cheap inclinometers. You can get a pretty good estimate from a $10 construction inclinometer.
If you want to do it yourself, you would need an angle finder.
Check where you're parked with the angle finder first. Make sure you account for that when setting the caster. If your driveway is at +2 degrees angle, then you should add 2 degrees to where you should be at for caster.
Place the angle finder on top of your ball joint if you can, or the flat section of your C knuckle if you have to. I'm not too familiar with ZJs, but I found this real quick.
> I also found the factory specs in the tsb about the offset ball joints. It says ideal target is +6.75 range between +6 to +7.5. Max difference between right and left is .5
You may need to be closer to 6.0 with a 4.5" lift so your pinion angle isn't too bad. If it causes vibrations you may need to go even lower on caster, which of course would cause more wandering. The only remedy for correct caster and pinion angle is to cut of the C's and have them welded back on to point the pinion towards the transfer case with the correct caster.
