The brackets are installed at the No. 1, 2 and 7
roadwheel arms to keep them from moving beyond
their limits. If the brackets are damaged or missing,
the roadwheel arms move too far and you end up with
broken shocks and torsion bars.
So eyeball the bump stop brackets as part of your
after-operation PMCS. Report any cracked, bent or
missing brackets to your mechanic.
He’ll replace the bump stop bracket behind the No. 1
roadwheel with NSN 5340-01-180-9847, behind the No.
2 roadwheel with NSN 5340-01-065-6143, and behind
the No. 7 roadwheel with NSN 5340-01-180-9846.
Shock Inspection
While you’re looking at
the bump stops, check the
shock
absorbers
for
leaks.
The
oil
level
should
be
halfway up the sight glass on
the shock housing.
After
operation,
check
for cold shock housings. A
housing that’s colder than the
rest may not be working. Tell
your mechanic.

a high-performance
sports sedan,
but you
still
want
the ride to be as
smooth
as possible.
That’s why it’s
important
to keep
an eye on the
roadwheel arm bump
stop brackets!
