i have a 1994 z28 and for a while a rattling started at the right front passenger wheel . i changed my tires 1 year ago and noctised the same wheel is lose. i mean u can take tire and wiggle it up and down . and yes the lug nuts are tight . the other front wheel is fine . also it only make noise when the automatic trans is in gear and iam stoped sounds like the brake ratling when i put car out of drive in N or take of the rattle is gone ? what is this ? iam not sure ?

my option might be the bearnings is why its lose, but why the rattle? now it does it some times when its in netraul and at idle like its getting worse ? what does these sound like to you ?
