1998 CLK 320
So when I start my car it it runs fine, but when I put it in gear it vibrates. I am thinking either the motor mounts or the harmonic balancer. Does anyone have any ideas?

 

It is likely the harmonic balancer. Your year car is actually having the balancers recalled. So check before you buy one.


The concept of a harmonic balancer sucks anyway.
Sorry, I almost went on a rant but I stopped myself.
