Tried searching...haven't the right words to search I guess. When accelerating or letting my foot completely off the throttle, my JK tends to "twist" a bit. Like something in the rear end is super torque like. Checked motor mounts. All lift parts are tight. I'm stumped. Help!

Have you regeared? If so, what are they?

Driveshaft & joints? Pinion angle?

Regeared it year before last. I have a 3.5 RE lift...35's...5.33.

Someone has told me my driveshaft could be tweaked. Not sure that I hit it though. The is spewing front and rear from what looks to be the pinion seals. Possible connection? Fluid seems to be flung out that little weep hole of the rear driveshaft.

They should not be slinging grease. Are they the stock shafts or aftermarket? Also you regeared to 5.13 or 5.38?

Dont know your specs, but if you lifted and your trac bars are not sitting level to the ground, the rise and fall of the front/rear end under accelaration and deceleration will make the body feel like it is "twisting" due to the fact that the trac bars mount in opposite directions front to rear. This is causing your front axle to shift slightly to the right on accel, left on decel. Rear will do exactly the opposite making this feel far worse than it is. The shorter the wheel base the worse it is. just my 2 cents.

Its axle rap, and body torque. Depending what spring rate you are running this can effect your squat and roll. Ever watch a drag car? Its the same thing a softer spring or shock combo can cause this. My friends Grand did this after installing rancho 9000 shocks. Change to a harder shock and this will help also what springs did you use? Shot my 2dr on launch will squat 2 inches rear an lift 2 inches front, and on letting off gas will drop about 2 inches in front. Plus mine torques to the right. Meaning the left front wheel is lifting on take off.
