Removal Procedure
1. Turn the steering wheel until it is horizontal, with the
spokes pointing down. This is the straight–ahead
position. Make a mark on the stub shaft housing
that lines up with a mark on the intermediate shaft
lower universal joint. This mark will be used for
proper alignment during installation.
2. Remove the lower pinch bolt from the universal joint
on the intermediate shaft.

2. Install the dash seal retaining ring with the nuts.
Tighten
Tighten the dash seal retaining ring nuts to 7 NSm (62
lb–in).
Important : When attaching the upper universal joint, the
steering wheel must be placed in the straight–ahead posi-
tion with the spokes pointing down.
3. Attach the upper universal joint of the intermediate
shaft onto the steering column.
4. Install the pinch bolt into the upper universal joint
on the intermediate shaft and tighten the bolt.
Tighten
Tighten the upper intermediate shaft pinch bolt to 22
NSm (16 lb–ft).
Important : When attaching the lower universal joint, the
marks on the intermediate shaft and on the stub shaft
should line up.
5. Attach the lower universal joint of the intermediate
shaft onto the steering gear stub shaft.
Important : When installing the lower intermediate shaft
pinch bolt, make sure the bolt goes through the universal
joint on the side of the stub shaft with the notch. If you have
trouble seating the universal joint completely down onto
the stub shaft, rotate the steering wheel slightly while
pushing down on the universal joint.
6. Install the bolt into the lower universal joint on the
intermediate shaft and tighten the bolt.
Tighten
Tighten the lower intermediate shaft pinch bolt to 22
NSm (16 lb–ft).

Removal Procedure
1. Siphon the power steering fluid from the fluid reser-
voir.
2. Raise and suitably support the vehicle.
3. Disconnect the power steering gear hydraulic cylin-
der pipes from the power steering gear at the valve
end. Replace the O–ring seals as needed.
4. Disconnect the power steering gear hydraulic cylin-
der pipes from the power steering gear at the cylin-
der end.
5. Remove the steering gear hydraulic cylinder pipes
from the vehicle.
Installation Procedure
1. Lubricate any new O–ring seals with power steering
fluid.
2. Place the O–ring seals into the housing and install
the steering gear hydraulic cylinder pipes.
3. Connect the power steering gear hydraulic cylinder
pipes to the power steering gear at the valve end.
Tighten
Tighten the hydraulic cylinder line fittings at the valve
end to 18 NSm (13 lb–ft).
4. Connect the power steering gear hydraulic cylinder
pipes to the power steering gear at the cylinder
end.
Tighten
Tighten the hydraulic cylinder line fittings at the cylin-
der end to 28 NSm (21 lb–ft).
5. Lower the vehicle.
Notice : When adding fluid or making a complete change,
always use DEXRON®–II or III power steering fluid. Fail-
ure to use the proper fluid will cause hose and seal dam-
age and fluid leaks.
