Will do.  :y Got plod spec front springs arriving soom which will definitely go on there. Also plod spec front dampers. If I can find a way of ascertaining if they are still  in good condition internally, hopefully without fitting them on the car to find out, they will also be going on the car.
So, need to get a pair of top mounts, then get it all fitted and get wheels aligned again. :)
I think I'm going to have to name it Triggers broom 2. So many parts renewed in less than a year of ownership. :D
Any suggestions on top mounts from the good doctor ?

Affirmative. I once changed drop links but failed to properly tighten bottom nut. That caused a knocking noise until properly tightened. With car over pit and son bouncing car fault was obvious.

Not yet. On a run of nightshifts at the moment. Got a pair of springs & dampers arriving in the near future. Will buy a pair of topmounts and bung the whole lot on there.
Its all done 175k miles, so must be past its best.
I'm pretty convinced that the damper is shagged. The front is rather bouncy now, even by Elite standards.
Car isn't used as a daily, so its not desperately urgent.

Update. I have fitted the plod spec dampers & springs along with new Pedders Monaro spec top mounts and new top mount bearings.
I cant believe how much stiffer the front of the car is now, but when I removed the old dampers it was obvious that there was very little compression damping left in them.
However, there is still a bit of knocking over bumps from the n/s/f. Not as bad as it was and not quite the same, but I'm surprised it hasn't completely gone as everything suspension & wishbone related has been changed.  :-\

Any play on the caliper?

Is the horn still securely attached?

Pretty sure calipers are fine, but may be worth another check. Hadnt thought of horn. Will have a look.  :y

I just had a really noticable bang everytime I touched the brakes and a noticable "budge". The driver side outer tie rod had massive play in it causing really unsteady steering and massive knock.

Swapped it today, made everything a lot better but I still have the passenger side lower control arm rear bushing completely busted as the control arm is resting against the body causing more play and random knocking.

Tie rods are fine. Control arm bushes are new. A couple of hours ago I found the strut to steering knuckle bolts weren't as tight as they should be, so I tightened them to the spec in Haynes manual. I thought I had found the cause, but a test drive showed it is still there.  :-\

Almost gave myself a hernia doing just that earlier. When I get the chance I think I will slacken everything off again and carefully torque everything up carefully from scratch.

As a thought, have you done anything with the arb bushes? Might be worth checking the clamp bolts while you're there... Can be done from the side with a regular spanner, 13mm iirc ;)
