2010 HB Bent Axle??

[Pacman]

Looking for some help with my 2010 HB rear suspension with 130K miles. The driver's side rear has looked lower for some time now. Though I never really measured, but guestimate was about 1/2". Thought it was my fat that had collapsed that side more than the passenger side. So thought it might be a good excuse to get a lowering kit and replace the worn parts. Bought a set of Tein adjustable springs/coilovers. Installation went fine and also installed a TRD rear sway bar with no fitment problems. By the way electric impact wrench was the best purchase ever for this project.

Put the car back on the ground and began adjusting springs to even them all out. Was shooting for 14" center of wheel to fender lip all the way around. Kept getting close but can't get the driver's side rear within a 1/4" lower than the other 3 corners. So I get 13 3/4" on the driver rear and 14" everywhere else. I'm actually at the end of the rear spring adjustment on that side, while the passenger side is about 1/4 of the way from the end.

Funny thing is if I keep lowering the passenger side the driver's side keeps staying 1/4 lower. There have been know unusual noises or vibrations with the old parts or the new.

Do I have a bent hub or axle? Could the rear axle body mounts be off? Is this common? Any suggestions or thoughts?

Thanks in advance.
