called Castor/Cam kits cos they do both jobs on depending where they are fitted... you have 4 bushes.... 1 kit = 2 bushes... best to fit 2 kits.. Repco costs $98 each kit..... i was told its 2 to 3 hour job to do for the pro's.... $65 for 4 wheel alignment... need to align the front wheels again too... make sure you ask the alignment place about setting the rear axcle end float 1mm to 1.5 mm i think... or the axcles will push your diff bearings into the diff... that would be very nasty stuff... fill your fuel tank up or put 50 klgs weight in the boot... helps to copy a loaded weight....
