NOTE: There are currently two cross-
members being shipped. One has spacers
welded as indicated in ILLUSTRATION 18b, one
does not, ILLUSTRATION 18a. If you have a
crossmember with the spacers welded in place,
DO NOT use spacer (90-2075). If you DO NOT
have the spacers welded in place, you must
use these spacers as indicated.
19) Using the differential mounting spacers
(90-2166), hex bolts 1/2” x 11” Lg. 1/2” washers
and nuts, fasten differential to front crossmember
(ILLUSTRATION 18). Fasten rear differential
mount to rear crossmember using existing 12mm
hardware. (ILLUSTRATION 19). Torque 1/2” nuts
to 90 ft./lbs. and existing 12mm nut to 64 ft./lbs.
20) Install existing lower a-arm into the front and rear crossmember on both sides of the vehicle using
the existing front and rear adjusting cam-bolt assemblies (ILLUSTRATION 20). Refer to the index marks
on the cam-bolts. Snug hardware, but do not tighten.
21) Install the steering yoke extension (90-2169) onto the splines of the lower steering shaft. Fasten,
using button head, 5/16” hardware (ILLUSTRATION 21). Compare 90-2169 to the factory yoke paying
close attention to the indexing of the clamp bolt and the lower bolt holes. Two different versions exist from
the factory and the rubber isolator may need to be removed and rotated 90 degrees to properly center the
steering wheel.
22) Loosely attach pressure line (90-
4029) to control valve on power steering
unit (ILLUSTRATION 22).
23) Install the power steering return line
(90-4030) to the spool valve
(ILLUSTRATION 23). Orient the return
line nipple to the vertical position and snug
down.
24) Install power steering unit
(ILLUSTRATION 24) using hardware pro-
vided; fasten loosely. Slide steering shaft
down into place on control valve coupler
(ILLUSTRATION 21), then tighten and
torque nuts to 26 ft./lbs. Tighten 5/16”
