Definitive answer please.

I have oil, which appears to be coming from the front upper control arm bush, I’ve done a little research, but I’m getting conflicting answers, are these bushes oil filled? I’m assuming they are, as I can’t see the oil coming from anywhere else, thanks in advance.

Well people, I’ve done a bit more digging and found they are indeed, fluid filled, thanks for any further input though, you may be able to give.

I don’t think they are buddy ?

Solid rubber afaik.

Would need a vin to be 100% .

They are called 'hydrobushes' for a reason... yes, they are oil filled, and yes, they can leak.

I had mine replaced, but my advice to others is to replace the entire control arm (including the ball joint on the other end), rather than replacing only the bushes - the work required to replace the bushes within the arms negates any saving on the parts. Oh, and the car will need to have the tracking checked afterwards.

Thanks for the replies, yes I think I’m going to replace all four whilst I’m at it, pretty simple job, so I might as well.

I've checked my glc against the vin and all mine are solid rubber .

Obviously yours may be oil filled as it's a different model.

Here’s a view of the problem, not my car, but exactly the same.

Yep looks busted . Id think your lemforder replacements may well be solids . ??

The replacements will be solid rubber, but you cant tell the difference between them from the drivers seat.

 

[toteimerced]

Glad to know, I’d rather they were solid, febi sell hydro versions.

Proper explanation here:

HYDROBUSHING

The main role of a bush is to absorb the various forces applied to the control arm. It achieves this through its elasticity:
