For the last 2 weeks I am noticing a steering vibration which starts around 49mph and end around 72mph. The peak vibration takes place around 66mph.
Almost one month ago I had both engine mounts replaced (the transmission mount was also replaced).
The car is a 99E300TD with 78k miles on it.
I checked the steering fluid and is OK - I also looked under the car & seen nothing to be concerned.
Any advice on what it could come from?
