Ok, i took my wheels off today for the first time to give the undercarriage on my 08 xtx a good cleaning. BUT some of my lugnuts stripped a little bit when coming off. I got them all back on (carefully) but there was ONE stud that snapped off. anyone else have this problem??? im thinking (and guessing) that the nuts are aluminum and the studs are steel so the metals are fusing (oxidizing)??? does anyone know a stud that cross references with the ac stud/thread pattern??? my dealer said he doesnt have a part number/listing for studs.
