5.1 NOTE!
Illustrations hereafter are with a section of the trailing arm removed
from the vehicle and are all "R" (offside) assembly. Refer to manufacturer's
service manual, or proprietary manual when using these instructions.
5.1.1 Jack up the vehicle, placing the jack clear of the rear suspension allowing it
to swing down.
5.1.2 Support the rear suspension whilst removing the trailing arm bush mounting
nuts, bolts and washers. Unclip the handbrake hose and associated fixings.
It may be necessary to remove further fastenings to allow the trailing arm
to fully sweep beneath the vehicle, enabling maximum access and
clearance for the bush extraction tool. Continue supporting the trailing arm
and controlling during lowering.
5.1.3 With the area around the suspension now clear we suggest a thorough
clean to avoid accumulated debris interferring with precision fitting
processes. Spraying a proprietory 'free release' fluid on to the bush sleeve
and housing may assist with removal in 5.1.7.
5.1.4 Note the orientation of the existing bush before removal. The method of
marking is best decided by the engineer. A scribed line on the bush
sleeve><and a mirrored orientation mark on the housing would give an
accurate orientation, for example see Fig.7. See also the manufacturer's
instructions.
5.1.5 Offer the 15mm 'C' ring on to the pressed steel housing, aligning the gap
with the handbrake cable bracket. This will be held in place (Fig.8) by the
three permanent magnets inserted in the ring. Ensure it is seated correctly
on a grit free face.
5.1.6 Access and adequate clearance is essential for offering the bush press
assembly over the trailing arm and bush housing. Weave the bottom plate
end over the "Tee" plate (Fig.9) and locate the counterbore with the 'C' ring
(Fig.10). Continue to support the opposite end with your hand (Fig.11).
It may be necessary to disassemble and reassemble the press
frame insitu when access is limited.
5.1.7 Two people are now recommended, with one continuing to support the
press frame and the other positioning the adaptor (Fig.12), stepped end
inside the bush sleeve. The shoulder of the stepped end will offer thrust
to the steel bush sleeve. Please note for the removal of the bush, 360°
orientation of the adaptor is not important and the side 'depth control legs'
are not fitted. The second person can now wind in the thrust screw
ensuring concentricity and squareness of both the press frame and the
cylindrical adaptor. With a 16mm socket increase the torque and observe
the bush sleeve projection from the housing, through to removal. Excessive
torque, above 180NM, is not envisaged, but if this occurs, stop and check
alignments. There may be some resistance initially. Continued support to
the press is required throughout, especially when the bush is removed
from the housing as the bush is then free to fall. Remove the old bush, the
press frame and prepare details for insertion of a new bush assembly. An
"exploded" view (Fig.13) supports actions shown in (Fig.8) through (Fig.12)
