they are loosened or removed.
Do not install bolts and nuts
coated with undercoating wax,
as the correct tightening torque
cannot be assured. Always
clean the threads with solvent
before installation, or install
new parts.
Do not attempt to weld or
straighten any suspension
components. Replace damaged
parts.
CAUTION!
Due to the aluminum

great care must be taken when
working on and around the front
suspension:
When replacing any damaged
front end components, always
check the condition of the
control arms
Do not clean control arms with
wire brushes made of brass or
iron. Only use brushes made of
stainless steel.
