Hope someone can help. Installed a bmr rear sway bar and lowering springs today. I did the front yesterday and all went well, car drove great. Today's install went fine, however when I raised the car to remove the jackstands, the jack failed just after I'd moved one stand and the car fell about 3" before the remaining (drivers) stand caught it. Of course this twisted the vehicle at a bad angle and I got it back up as fast as possible. Couldn't find any damage however, upon test driving it I noticed it's now pulling hard to the right and I've got the "service stabillitrak" message. Visual inspection reveals nothing unusual front or back. Anyone have any ideas? I want to do a little trouble shooting if possible before taking it to the dealer as I know they're going to question the spring/sway install. Thanks!
