Just put my TL bar on today too...holy crap my hands hurt from using a hacksaw to cut off the old end links! Maybe it is just me, but while driving I rocked the car back and forth quickly and it didn't seem to lean as much. Gotta love it!
My rear swaybar bolts were not coming off, and I didnt want to buy new ones, SO I used an Impact gun,
They came right off.
So to anyone having trouble I would suggest Dousing the nut with penetrating oil and Hitting them with an impact gun.
It may save you some money, and work.
Then be sure to use anti seize when installing the new nuts
