I have a 2000 s500 with 18 inch OZ opera. I recently replaced 2 bent rims and now the wheel balance at the local tire shop and MB Dealer show the wheels true but I am still getting right rear vibrations around 60-72 and more noticable from deceleration. At the MB Dealer I noticed a little oil on the right front wheel well and yesterday light oil spry on drivers side rear. They thought I just ran over something.

Anyideas are the two things related? I have a road trip to take in 5 days and I need to know if my car is safe.

 

the oil in the front most likely is not related to your vibration since you stateed that it is in the rear ... but, will oil spray coming from the rear wheel area you may want to check your rear wheel bearing and axle sleals

 

Luke after switching wheels and everythoing they tell me I have a slight bent rim yet the wheels show balanced. I am confused can you enlighten me?

 

you can actually balance a cube but, it won't roll smoothly .... that diagnosis makes perfect sense .... just because it is balanced doesn't mean it is round
