Completely new upper and lower arms for the pivot ball steering. Uprights also, which are much stronger than the previous design. Uni's instead of CVJ's for the front drive shafts, and a uni replaces the dog bones for the front center driver shaft.
The PBS - two different cups, either a non-adjustable quick and easy one piece cup (top right) or the adjustable three piece cup (top left):
Grub screw to adjust the play in the PBS. On the left you can see in the hole the plate the grub screw butts up against, which sits behind the plastic cup.
Tip: Screw the pivot ball shaft into the arms before putting the caps on, so you can use the hex head in the shaft to do it up rather than fiddling around with a small trurnbuckle spanner.
