Hi,
my Mazda2 just pass about 45.000km after two years and I realized problem with gritting (like an old rocking chair). I can hear it in low speeds almost when I am going through some rough holey road very slowly, it's coming from the rear. When it's most hearable it's in our undergroung garages when I am driving very slowly from one floor to another and the car must go through the quoin in sublevels between floors. It was at dealer, they told me thay tighten everything they can but it didn't help

.
The second gritting noise comes from the front, mostly in the situation when I am driving away from the crossroads and changing gear from 1st to 2nd . Problem is that these sounds go away after about 30minutes of driving, so I can't prove it to the dealer, coz in time when I get to them, sounds are away and I would have to wait till the morning to get dealer serviceman with me to the ride and show the noises him...
Have somebody ideas? Thank you very much.
