My 2004 bmw 325I rides rough and vibrates starting at around 45mph and stops about 75.
Its the worse at 60mph and it shakes really bad. What is the cause???
it could b a number of things, one of the front tyres may be out of shape it could be that one of the alloys has warped or the front wheels need balancing. Best thing to try is to swap the front wheels for the back coz it wont be so bad on the back and it also lets u know that there is a problem with one otr the wheels in some way.
cheapest and most likely is that your wheels are out of balanced its 20$ for a rebalance of all 4 at walmart
could be a whole bunch of problems but ensure that your lug nuts arent slack, also check that your tyres are in good condition
