Vibration

[Fidalio]

I have an E220 Estate which has developed what I can only desbribe as a drumming vibration.

At first I thought it may have been the wheel balancing (is wasn't as I had them rebalanced - never a bad thing) and when the vibration was still apparent I thought it maybe a wheel bearing. However, I then noticed that the vibration only showed itself whilst under acceleration (not hard either) but stopped whilst cruising or deceleration or braking. However, if it were a wheel bearing, my logic tells me that the vibration would still show itself under deceleration or braking and not just acceleration.

Any ideas?

Many Thanks

Couple of things, where do you feel the vibration? through the wheel or the seat?
Could be engine mounts going hard over time. How old is your 220?

Engine stabiliser

There is a stabilising damper which can often cause a similar problem, but its also worth checking the condition of the mounts. Also take a look at the radiator fan-cowel. has the fan been catching the coweling? this is a sure sign of a bad engine/gearbox mount. Good luck

Through the seat and the vibration gets to your ears during a long drive. It is a 1996 model.

Spectre,

The radiator fan-cowel is just fine with plenty of clearance and no sign of catching.

Cheers.

Through the seat vibration is more likely to be from the rear of the vehicle and not steering/front wheel related. Rear track rod bushes or wheel bearings, warped wheels, possibly propshaft / driveshaft but not common on MB's.

I did wonder about the driveshaft. I will be taking it in this week, as the anitipated level of remedial work has gone beyond my own level of skill, so I will let you know.

Best Regards.

Turned out to be a badly worn support bearing on the drive shaft.

Fortunately I caught it in time as had it gotten any worse then the diff and drive shaft could have been affected therefore needed replacement.

However the worst part was I asked them to sort out the drivers window while the car was in (it wouldn't open but I could hear the motor whurring away). Turned out the rectifier was shot and cost me £504 just to get the window sorted.

I think he probably means regulator Malcolm.
