Beg to differ. The caster wedges are 2 wedge shaped pieces of aluminium
about 10 inches by 2 inches that are fitted between the chassis and the
front cross member. This causes the cross member to be higher in the front
than back and provides the caster angle, that being the amount that the
lower steering ball joint is in front of the upper. This provides the self
centering effect of the streering.
The corrode if in a damp climate (ask me my car came from the UK) expand and
can actually bend the crossmember.
Replacement is surprisingly easy (couple of hours).
