C class wipers

[sja]

2008 c class 320. Still waiting for dealer to sort vibration, buckled wheels, dodgy parking brake etc..

But

Raining today , wipers bang on edge of windscreen. Very annoying.. Easy fix?

Thanks

Thanks, look right size.. And Mercedes own make.. Maybe another trip to garage.. It's back at dealers getting wheels attended to, on a plus note the Yaris he loaned me doesn't vibrate and the wipers are quiet..
