Just an update - typical Jeep dealership only sells the complete LCA over here, not the bushings by themselves. So, instead of a $20 part, they are trying to sell me a $700 part (over here).
Rockauto to the rescue! New bushings and a couple of other bits are on the way over. In a few days, hopefully the beast will be CLONK free.
When it was having the rack change I also got the guys to do the pinch weld mod while the wheels were off. Now the tyres don't rub on half lock!
Bilsteins hopefully arriving from Kolak at some point soon too, so will get all the changes and realignment done in one job lot.
