Power steering servo pump rattles - PeachParts Mercedes-Benz Forum

I recently noticed -at idling- a light rattling noise that appears to come from the power steering servo pump. Would like to know if this is a common failure.
Is this pump an expensive part?

Thanks!

That would be my guess too. The belt tensioner shock is well hidden behind stuff like the water pump, and when the shock bushing is worn, it clanks while the engine is idling.

A $2 or $3 fix. There are some threads posted about this symptom and its cure...

THANKS lads! Will check this out..!

btw, one way to check this is to push against the belt tensioner shock while the engine is idling. If the noise stops, you've found the problem...

You mean, stick my hand/arm there while the engine is running...

I'll ask my neighbour...
