Hi All,

I have a 2006 STI.
Its fitted with AST coil overs etc.
The drivers front one was changed about 2 month ago.
There is a knocking noice now on the drivers front susspension, appeared a week or so ago.
It only does it when going over a pot hole etc, not a bump, speed bump etc.
I took the wheel off, disconnected the drop link and that was nice and tight.
I jacked the hub up and tried with a bar to check for play in the bottom ball joint, no movement.
I tried the same on the track rod end, same.
Any ideas what else to check and how to check it?
