Check the end-play with a dial indicator. If it is correct,

pin.

Technique Two
Hold the hub carrier vertically in a vise with the inner end
of the hub uppermost. Place the special collar tool (Jag
tool No. J15) on the hub end. Place the inner bearing
inner race on the hub and press the race onto the hub until
the inner face is flush with the special collar. This will
provide end flat bearings. The end float should then be
measured with a dial test indicator. A spacer should then
be fitted in place of the Special collar to give end float of
.002"-006". Spacers are supplied in the thicknesses shown
below.
For example, assume the end float measured to be .025".
Subtract the nominal end float of .004" from the measured
end float giving .021". Since the Special Collar is .150"
thick, the thickness of the spacer to be fitted will be
0.150"- 0.021" i.e. .129". The nearest spacer is 0.128" or
0.130". For competition, use the spacer yielding more end
float.
When the axle shaft has been fitted and nut tightened
(140 lb.ft.), check the end float with a dial indicator. If it
is correct, tighten the nut to the next near hole and install
the cotter pin.
Install both the seals into the hub carrier.
Re-assemble the hub carrier with hub and axle.
Install the washer and retaining nut. Tighten the nut to
225 lbft. Without an air wrench, you may want to wait
until the car is on the ground for final torqueing.

Install the upper bracket onto each hub carrier and torque
the bolts to 75 lb-ft. Note the orientation below.
SUBFRAME
Rebuild the differential as necessary. Some units have a
separate caliper mounting bridge on the side bearing
housing. This bracket and the original Jaguar rotor can be
left off.
Place the differential on the bench, right-side-up. Raise
the back up about
3 /
4
" with a block of wood, etc. Place the
the top section of the subframe over the differential, lining
up the 4 holes.
Loosely bolt the top of the subframe to the
top of the differential with (4) 1 /

"L bolts, flat
washers and lock washers.
