WHAT'S THE SECRET IN INSTALLING REAR HUB

1985 Jaguar XJ6 • 12,600 miles

I keep lining up the shaft with the hub, but it just won't go in.

REAR HUB & CARRIER ASSEMBLY, HALF SHAFT & BRAKE ROTOR
Removal
Jack up rear of vehicle and support on stands. Remove rear wheel. Remove safety wire from
radius arm mounting bolt and remove bolt, then lever radius arm from spigot anchor point.
Position support block under outer suspension arm.
1.
Detach lower shock mounting nuts, washers and towing bracket, then remove shocks from
lower mounts. Loosen clip holding inner universal joint shroud and slide shroud away from
flange. Remove nuts holding universal joint to brake rotor.
2.
Tap rotor mounting bolts toward final drive unit. Carefully separate universal joint from brake
rotor (collect camber adjustment shims held on rotor mounting), detach brake caliper and
remove rotor from mounting bolts.
3.
NOTE: Do not disturb rotor locating shims mounted between differential
flange and brake rotor.
Withdraw cotter pin, then remove nut and plain washer from splined end of half shaft. Remove
grease fitting from hub carrier. Fit Thread Protector (JD.1 C/7 ) over end of half shaft. Using
Puller (JD.1 D ), pull hub and carrier from half shaft. Remove hub puller and thread protector.
Pivot hub assembly down on outer wishbone (suspension arm) fulcrum shaft.
4.
Remove spacer (Bronze) from half shaft. Inspect inner oil seal track and replace track as
needed. Remove 1 nut from fulcrum shaft. Using soft-faced hammer and drift, drive shaft out of
hub and carrier assembly and wishbone bracket. Insert Dummy Shaft (JD.14 ), if necessary.
Remove hub and carrier assembly from vehicle as required.
5.
NOTE: When removing hub and carrier assembly, note shim and washer
locations for reassembly reference.
Fig. 1: Removing Hub & Carrier Assembly From Half Shaft
NOTE: A puller must be used to remove the hub and carrier from the
splined end of the half shaft.
If necessary, detach upper mounting bolts and nuts, then remove forward and rear shocks.
Detach 4 nuts securing half shaft flange-to-stub axle flange and brake rotor. Pull half shaft from
suspension unit noting number of camber shims installed between half shaft flange and brake
rotor.
6.
NOTE: If necessary, remove universal joint shields by drilling out rivets
and removing clips.
Installation
To install, reverse removal procedure. If necessary, replace joint shield. Ensure grease fitting
access hole is positioned correctly. Cover joint lines in shield with non-hardening waterproof
sealing compound.

NOTE: Be sure to replace camber adjustment shims.
To reinstall rear hub, install dummy shaft in hub carrier fulcrum. Position carrier on suspension
arm, installing shims removed from between carrier and suspension arm. Replace outer
suspension arm fulcrum shaft, displacing dummy shaft. Secure shaft with nut and reinstall
grease fitting.
2.
If necessary, install oil seal track to half shaft splined flange. Replace spacer. Thoroughly clean
and degrease splines of half shaft and bore of hub. Using a small brush, sparingly apply Loctite
to outer two thirds of half shaft splines.
3.
Assemble hub carrier to half shaft. Install washer and tighten hub carrier assembly nut. Install
new cotter pin. Install dial indicator with pointer against hub. Push in on hub and zero indicator.
4.
Using 2 pry bars, pry out on hub and measure hub bearing end play. If end play exceeds
specifications, overhaul rear hub and carrier assembly. After installation of rear suspension in
vehicle, check rear wheel camber and readjust as needed.
