Vehicles with up to 110 kW engine Page 48-90 . Vehicles with 128 kW engine Page 48-97 . If reservoir fluid level is low then check steering
system for leaks.
For leaks at the pinion first check the lines/line
connections for leaks and if necessary tighten
and wipe dry.
If the pinion seal or the rack seals in steering
box housing are leaking then replace steering
gear.
To check the rack seals loosen the clamp on
the boot and push to one side. Page 14 of 99Steering12/7/2004http://ebahn.bentleypublishers.com/vw/servlet/Display?action=Goto&type=repair&id=VW.B4.SU01.48.1

Power steering gear, removing and
installing

When working on the power assisted steering
gear:
Absolute cleanliness is required when working
on the power steering.
Thoroughly clean connections and immediate
vicinity before loosening.
Place parts on a clean surface and cover if not
re-installing immediately.
Do not use fluffy cloths. Only unpack parts immediately prior to
installation.
Only use genuine packed parts. Vehicles with four wheel drive observe installing heat shield. Page 15 of 99Steering12/7/2004http://ebahn.bentleypublishers.com/vw/servlet/Display?action=Goto&type=repair&id=VW.B4.SU01.48.1

Removing - Press tie rods off steering arm. A - Ball joint splitter (commercial type) e.g. Kukko
No. 128/2
- Remove partition behind pedals from bulkhead
and from steering column tube to loosen the
universal joint/power steering gear. If an oil extraction unit is not available, disconnect
vane pump supply hose and drain hydraulic fluid. - Loosen nut on the universal joint (arrow). - Remove hydraulic fluid from reservoir with an oil
extraction unit, e.g. VAG 1358 A or VAG 1307 A. Page 16 of 99Steering12/7/2004http://ebahn.bentleypublishers.com/vw/servlet/Display?action=Goto&type=repair&id=VW.B4.SU01.48.1

Instead of plastic sealing plugs a plug consisting of
Part No.113 301 229 A and banjo bolt, Part No. N
904 674 01 can be used. But when using these,
several 16 mm diameter sealing rings must be used
so that the holes in the banjo bolt are sealed. - Support engine/transmission assembly with 10-
222 A and 10-222 A/1 (support VR6 engine with
10-222A and 10-222A/3).
- Remove boot from seat on steering gear. - Remove subframe bolts. - Lower engine/transmission assembly; this will pull
the two halves of the universal joint apart.
- Disconnect hoses from steering gear and seal with plastic bag and adhesive tape.
- Seal power steering gear threaded holes with
plastic sealing plugs.
- Remove steering gear securing nuts (bolts remain
in subframe).
- Remove steering gear rearward. Page 17 of 99Steering12/7/2004http://ebahn.bentleypublishers.com/vw/servlet/Display?action=Goto&type=repair&id=VW.B4.SU01.48.1
