I need to change my battery on my 2003 P5 but the sway bar bolts are super tight. Am I a weakling or what? I dont want to strip the nuts. I think it was 17mm socket which started stripping the bolts already. What am i doing wrong.
Make sure you are using 6 point sockets instead of 12 points (less chance of stripping). If they are that tight remember that quick bursts of force are better/safer than slowing putting more torque on it. Beat on the ratchet handle with a hammer or use an impact driver/wrench. Wd-40 or PB blaster might help.
Also make sure you are turning it in the right direction.
