(a) Remove nut from outer tie rod (Fig. 3).

INSTALLATION
NOTE: Front wheel dynamic toe pattern is critical in
controlling a vehicle’s directional stability as the
vehicle’s suspension moves through normal jounce
and rebound travel. Front wheel dynamic toe pat-
tern is adjusted by raising or lowering the mounting
height of the steering gear. This is accomplished
through the use of shims (Fig. 2). When installing a
steering gear, in order to maintain the correct front
wheel toe pattern of the vehicle, install the same
thickness shim as was removed. If not, front wheel
dynamic toe will need to be checked and adjusted
accordingly. Otherwise, the only time front wheel
toe pattern is required to be checked or adjusted is
if the frame of the vehicle has been damaged.
Shims (available in various sizes) are mounted
between the steering gear and its mount (Fig. 2). A
maximum of 11 mm (0.43 in. or 7/16 in.) shimming
is allowed between the steering gear and its mount.
(1) Install steering gear back in vehicle using
reverse order of removal through the left front wheel
opening.
(2) Lower vehicle to height where under hood can
be reached as well as under car.
CAUTION: Install the original toe pattern shims (Fig.
2) in their original locations when the steering gear
is installed in vehicle.
(3) Align steering gear with mounts on frame.
From top, install two steering gear mounting bolts
through gear and start driver side bolt into nut on
frame (Fig. 2). Reach underneath and start special
nut on passenger side mounting bolt.
NOTE: Shims installed between steering gear and
frame mounts must be oriented with their open
ends along the axis of the gear, that is, facing either
left or right. Shims are never to be installed with
their open ends facing to the front or rear of the
vehicle.
