Symptom 303000 Steering/Handling
Issue:
Some customer vehicles have reported leaking from the
Steering Gear. Dealers have replaced Steering Gears to
successfully fix the issue.
Cause:
An O-ring in the Transfer Pipes can in some cases
deform, which can result in power steering fluid leak from
the mating surface between the Steering Gear and
Transfer Pipes.
Action:
When a PAS fluid leak is suspected from the Steering
Gear Transfer Pipes it should be noted that these parts
must be replaced and not the Steering Gear, following the
outlined procedure. Please refer to the Jaguar Parts
Catalogue for part numbers.
1.Diagnosis – First confirm the area of leakage.
·Check the PAS fluid is set to the correct level in the
reservoir, refill if necessary.
·Clean off the Steering Gear housing.
·Start the engine and operate the steering from lock to
lock with the vehicle lifted off the ground.
·Confirm that the PAS fluid leak originates from the
steering rack transfer pipes.
Content 2.Removal
·*Cleanliness. Care should be taken throughout not to
introduce contamination into the steering system.
(See JLR workshop manual for correct working methods).
·Put the car on a ramp, remove the engine under tray and
drain the PAS system. (JLR workshop manual procedure
on Topix).
·Loosen the steering rack transfer pipe unions on the main
housing of steering rack.
·Remove the transfer pipe latch plate retaining bolt and
the latch plate on the pinion housing of the steering rack.
·Remove both transfer pipes from the steering rack pinion
housing and the main rack housing.
3.Fitting new transfer pipe assemblies
·Apply non-silicongrease or additive-free Vaseline (do not
use PAS fluid) andevenly spread onto the circumference
of the O-rings of new transfer pipes. *Take care not to get
the lubricant into the hydraulic system.
·Carefully push transfer pipes into main housing and
pinion housing of the steering rack.
·By hand, screw transfer pipe unions into the main
housing of steering rack.
·Refit the latch plate and latch plate retaining bolt to the
pinion housing of the steering rack.
