Turn the assembly upside-down. Install the bottom
section of the subframe by inserting the rear ears just in
front of the rear flanges of the top. Rotate down in the
front to match the front holes and loosely attach the front
with

”L hex cap screws and flat washers.
Align the rear flanges of the upper and lower sections with
the
5 /

bolts (flat washers on both sides) and secure with stover
nuts.
Use Grade 5 torque specs on page 158 for all fasteners
Loosely fasten the bottom of the subframe to the
differential using
1 /
2
"USS x 1 1 /
4
" bolts, flat and lock
washers. Shims may be necessary between the channel
and the casting, so don't tighten the bolts yet.
Tighten (in sequence) the top differential bolts, the bolts
between the top and bottom subframe pieces. If the
clearance between the differential and the bottom section
of the subframe is greater than .040”, insert shims to fill
the gap. Use a medium grade threadlocker on the bolts.
Install the bushings and side brackets on the front mount
tube. Tighten one castle nut to 5 lb-ft and back off so that
the slot aligns with the nearest hole in the shaft. Tighten
the second nut to 15 lb-ft and back off to the nearest hole.

Install a male (right-hand-thread) rod end and jam nut onto
each front lower radius arm so that the bushing center to
rod end center distance is 16". Leave the jam nuts loose.

Insert the bushings into the radius arms and lightly
lubricate the inside with heavy grease (silicone or moly
base is best). Install the hub carrier onto the front radius
arm. Loosely install the washer and castle nut.
Install the rear radius arm onto the hub carrier in the same
manner. Slide the other (inside) end into the bracket on
the subframe and temporarily secure with a bolt. Insert the

"L bolts through the connecting plates.
Tighten each castle nut to 15 lb-ft and back off to the
nearest hole. Secure with a cotter pin.
Bolt the half-shaft inner ends and spacer onto each
differential output flange. If you wish, install Jaguar
shims with about .060" total thickness between the half-
shaft and the spacer. This will make minor camber
adjustments easier after basic alignment has been done.
