Installing
- Install in reverse order of removal.
CAUTION!
Some fasteners are designed to be used only
once, and are unreliable and may fail if used
a second time. This includes, but is not
limited to, nuts, bolts, washers, circlips and
cotter pins. Always follow recommendations
in this manual-replace these fasteners with
new parts where indicated, and any other
time it is deemed necessary by inspection.
Bonded rubber bushings can only be turned
to a limited extent. The bolted connection
between the wheel bearing housing and the
upper control arm must only be tightened
when the vehicle is standing on the ground.
Otherwise the bonded rubber bushings will
be subjected to a torsional stress resulting in
shortened service life
- Check wheel alignment and adjust if necessary
