Good Evening,

Last week I brought my 2012 C300 4Matic into the shop, I told them there was a vibration / woobing noise between 70-76MPH, they told me it was my 2 bent rims and needed a high speed balance, They fixed the wheels and rebalanced the wheels and I went to go pick up the vehicle and it is still not fixed and the tech does not know what it could be. any help would be great.

Thanks

Did he check the balance on the rear rims also?(unlikely though)
You could check the new weights haven't been thrown off the front rims? if they are stick-ons.
