i just now found my car makes a weird squeaking sound when it accelerate from a stop...or when I'm stopping or if i hit a small bump it don't not do the noise if I'm in park and rev the engine....it does not do it all the time it comes and goes only when I'm accelerating or breaking or hitting a small bump i have a 2008 535xi with 65k miles i just got new tires and had a wheel alignment a month ago and this just started now
