Hi there...Welcome to the club.
As one of the resident gearheads.. I'd like to point out that there are many good suggestions above.
As well... we like to suggest the free or cheaper more common items first.
For example..not knowing the car ... you are unsure what is happening. If available jack up the car and follow the advice Gonneville mentions of putting your hands at 12 and 6 wiggle, then 3 and 9 wiggle. Report back any play.
If you aren't comfortable with that..then take it in to a tire shop. Have them rotate and balance the tires. Also ask if they can check for suspension wear meaning the wiggling like we just mentioned.
Your description of the problem is pretty vague and doesn't give us much to go on... let'* start off with the recommendations..check steering/suspension and tire balance. Report back your findings and we'll go further if necessary.
BTW..I've never heard of bearing rusting in a garage in a 3 month timeframe.
