Title: Is this supposed to move?
Post by: vale on May 09, 2026, 04:35:38 PM

I was looking around the inside of my downtown 300, and found that the rubber parts indicated with the right arrow are very loose (sorry about the description, english not my main language). The metal bar indicated by left arrow is firm, no movement.
Is this a 'normal' behavior? Or should i change those rubbers?

Can't see that much on your pic, but pls have a look at att pic...

This rubber grommet is supposed to be your engine suspension and should not be moveable by bare hands/fingers.

This stop nut in front has to be tighened (to pinch the damper-rubber) assuming both washers are still there.

If the grommet is worn out/hard/torn, replace it with a piece from any auto shop (OEM not available).

That's exactly the part I was refering. That top rubber (with the arrow pointing at it) is very lose, and there is at least 5mm between the rubber and the washer (which cannot be tighten more from what i can tell). The other rubber is fixed-at least with the engine off and static.

Take the rubber off, go to a autostore / sparepart shop and show them your part.
Take smtg similar but thicker, mount it.
