10•14 Suspension and steering
11 Before connecting the flexible coupling
make sure the steering gear is in the
straight-ahead position (see illustration).
12 Reconnect the flexible coupling as
described in Section 6.
13 Reconnect the tie-rods to the rack,
remembering to fit the washers under the rod
ends. (Note that the tie-rods are handed: they
are fitted correctly when their clamp bolts are
fitted from below). Fit the spacer plate or
damper bracket and tighten the bolts to the
specified torque, using new lockplates.
14 Refit the remaining components in the
reverse order to removal.

Removal
15 Refer to paragraphs 1 to 9, but
additionally the flow and return pipes must be
disconnected from the pinion housing. Allow
the fluid to drain from the open unions, then
plug the holes to keep dirt out. Introduction of
dirt may seriously damage the hydraulic
system.
Refitting
16 Refer to paragraphs 10 to 14. Top-up and
bleed the system on completion, as described
in Section 29.
28 Steering gear - overhaul
1 Examine the steering gear assembly for
signs of wear or damage and check that the
rack moves freely throughout the full length of
its travel with no signs of roughness or
excessive free play between the steering gear
pinion and rack. It is possible to overhaul the
steering gear assembly housing components
but this task should be entrusted to a Vauxhall
dealer. The only components which can be
renewed easily by the home mechanic are the
steering gear bellows and the tie-rod ends
which are covered elsewhere in this Chapter.

2 On models equipped with power-assisted
steering inspect all the steering gear fluid
unions for signs of leakage and check that all
union nuts are securely tightened.
3 Inspect the rubber mountings and pinion
gear cover renew them if the rubbers shown
signs of wear or deterioration.
29 Power-assisted steering
- bleeding
1 After any of the hydraulic unions has been
disturbed, or if the fluid level has been allowed
to fall so low that air has been introduced into
the system, bleeding should be carried out as
follows.
2 Top-up the reservoir with fresh clean fluid
of the specified type. Fluid drained from the
system must not be re-used.
3 If the pump is dry, start the engine
momentarily and then switch it off. Top-up the
reservoir to the lower mark on the dipstick, run
the engine briefly again and repeat the process

until the fluid level stabilises. It is important
that the pump is not allowed to run dry.
4 With the engine running at idle speed, turn
the steering wheel approximately 45° to left
and right of centre, then from lock to lock. Do
not hold the wheel on either lock, as this
improves some strain on the hydraulic
system.
5 Switch off the engine and correct the fluid
level.
30 Power steering pump
- removal and refitting
Removal
1 Remove the pump drivebelt, as described
in Chapter 1.
2 Disconnect the fluid feed and return hoses
from the pump. Be prepared for fluid spillage.
Plug the openings; being careful not to
introduce dirt.
3 Unbolt and remove the pump (see
illustration).
4 A defective pump must be renewed: no
spares are available.
Refitting
5 Refit in the reverse order to removal. Tension
the drivebelt, as described in Chapter 1, before
tightening the pump mountings.
6 Bleed the system, as described in Section 29.
Pay particular attention to the procedure
required to prime the pump if a new pump has
been fitted.
31 Power steering fluid reservoir
- removal and refitting
Removal
1 Slacken the reservoir clamp bolt.
2 Disconnect both hoses from the reservoir.
Be prepared for fluid spillage. Remove the
reservoir.
