1997 e320 wobbiling sound!!! any help??
 

when i get up to about 45 miles an hour and i ease off the accelerator it starts making a wobbiling sound!! it does it at all speeds higher than 45 miles an hour..but if i accelerate it smooths out!! any suggestions?? hub bearing or drive shaft support bearing??

I'm currently chasing the same kind of issue with my 94 C280, replacing the front bearings reduced the noise, I hope to change the center bearing next, as it seems to be the area the noise is coming from once I eliminated the noise from the front hubs.

so, I'd start with front hub bearings, then remove the driveshaft, check balance and replace center bearing, then if needed, the rear bearings.

Bad front flex disc?
