Front Tire Noise
 

Hi,
My CLK 430 with 180.000Km has developed a strange loud noise from the fornt tires. especially between 30 and 65 mph and also when i am braking untill stop the car.
Tire are BRIDGESTONE potenza in original size (16 inch 205/55 in front and 225/50 at rear). Brand new and with 20% of wear.
I changed ball bearings bud with no luck and after inspection tires seem to be ok without problem, the pressure is about 34 psi seem to be correct.
I checked other components but they does not show play under force (the force i can apply).
The shop said me that is a problem of parallelism and i need a chek ......
I need your help guys.........
many thanks
Alberto
