I cant figure out where this knocking sound comes from. Even the slightest unbalance on the road sometimes when braking I hear this knock sometimes it feels like it's going to pop out through the floor when Im driving. Now here's the list of things replaced once or twice in a period of 18 months:

Front shocks - replaced twice
Front springs - replaced twice
Front wheel bearings and hubs - replaced and all new
Lower ball joints - replaced twice
Upper ball joints - replaced twice
Upper control arm bushes - all replaced
Lower control arm bushes - all brand new
Tie rods and tie rod ends - all replaced
Sway bar links - replaced twice
Sway bar bushes - all replaced
Front rotors - all new
Tyres - all new
Tranny - all serviced
Diff - all reconditioned

I cant bl00dy think of anything else (Im not a mechanic but I have always been driving Fords since my F150 back in the 90's).

The mechanic basically puts in what I tell them to and they don't even suggest or find what is wrong. Is it because of shocks/springs that could maybe a little cheap being just normal ones the mechanics put in. Or are there other bushes Im missing or anything to do with sway bar that I haven't got to?

Hope anyone can help
Thanks

My AU111 needed the steering box bolts done up. Fixed the problem.

You beat me to it. :)

Might also want to check that the bolts in the Crossmember that hold the Steering Rack are solidly mounted.

maybe that explains why the noise went away when the tie rods and ends were replaced, maybe they bolted them all tight ... and now .... I'll get the shop to have a look and will post what they find thanks

all steering box bolts and everything else in front susp tightened and knocking noise still there, it even starts when I start to drive off in the morning to go to the station, very weird, could it be the shocks? but then these were replaced twice

this long expensive problem finally has been solved by just $20 fix.
The mechanics have replaced, upper and lower ball joints 3 times, front shocks/springs twice, all wheel bearings and hubs, upper and lower control arm bushes, links, swaybar bushes, tie rods and ends - same issue existed. Someone told me about a small suspension shop not far and they went through all - and starting knocking or replacing bolts to do with the sway bar and bang - all quiet. At least everything else is new. Just reporting back
