So we have disconnected the drop links on my 3.6 tdv8 to check were the knock is coming from as we were not sure weather is was the drop link s or ant roll bar bushes. we took one drop link off, drove it down the road and knocking gone. cm back to put new drop links on and the anti roll bar has moved up shortening the gap so the new drop link won't fit back on. how the hell do we get the anti roll bar back down again as its now practically touching the chassis and seems to be stuck there ?

You can either plug it into a computer and adjust it, or you can disconnect one of the oil feed pipes, move the bar then reconnect. You'll need to bleed the system afterwards (it's self bleeding, but drawing in that much air the system may struggle to purge it all under normal operation).

thanks, we,ve managed to move it slowly. PHEW !

If anyone reads this and decides to do something similar, I suggest disconnecting both drop links and pulling the wiring connectors of the valve block on the right underside of the vehicle. 2019 5.0 SC SVA (Current)
