Re: rubber missing, explains noice?
That's not the anti roll bar bush... that's a drop link.
The AR bush is out of view in the pic.. about 1 foot further up the AR bar.
2 new drop links + all rubbers set me back about 18 quid.
They are a common consumable on the 155s.
May as well replace both of them, the top bit of the mount won't be the best quality rubber at the moment either plus now one's gone.. the other won't be far behind.
You'll notice yer handling ain't as sharp at the moment either,, do the new drop links and you'll notice a differance.
