4.1 Trailing Arm - 'Old Style' bush and new 'Slotted' bush
(Fig.1).
With Kit VS4464 the old style bush can be removed from
the trailing arm and the new specification 'slotted' bush
installed ‘on-car’, without the need to remove the trailing
arm. By selecting and assembling the relevant parts in the
specific order required, bushes are removed and installed
by turning the force nut whilst counter-holding the 'locking'
nuts.
The replacement 'slotted' bush must be compressed in
order for it to be installed into the trailing arm and a
Compressor Sleeve is included in the kit for this purpose.
NOTE:
The Compressor Sleeve has a cut-away section at
one end, and when installing a new bush, this cut-away is
positioned at the bottom part of the face of the trailing
arm, to accommodate any raised area of casting, and to
ensure the Compressor Sleeve fits squarely and flush to
the face of the trailing arm. This ensures the new bush
enters the arm correctly.

4.3 IMPORTANT:
Prior to undoing the bolts securing the
trailing arm bracket to the vehicle, mark the position of the
bolts with paint so that the bracket can be re-positioned in
the same place when re-assembling, in order to maintain
rear tracking
(Fig.3)
. Undo the trailing arm bracket bolts,
release the brake pipe clamp off the arm and pull down
the arm to expose bush/bracket. Remove the bracket.
4.4 IMPORTANT:
Paint a mark on the trailing arm, to ensure
the replacement bush can be aligned correctly during
installation

4.5 Removing the old bush
The old bush is extracted out of the trailing arm in a
direction from the inside to the outside of the vehicle.
Assemble and fit all required parts from VS4464 Kit,
depending upon 'Old Style' or new 'Slotted' bushes being
removed, as shown in the removal assembly sequence
diagrams
(Figs 5 and 6).
IMPORTANT:
Turn the Force Nut Assembly by hand, to
take up any adjustment and to 'lock' the assembly onto
the bush ensuring the assembly is squarely aligned in
position on the trailing arm. Check that the feet of Bridge
Piece (3) are located through the bush and resting on the
arm. Counter-hold Lock Nut whilst turning the Force Nut
Assembly to extract old bush.
4.6 Installing a new bush
BMW have replaced the existing design of bush with a
'slotted' version. This bush requires to be pre-compressed
as it is installed into the arm. The new bush is installed in a
direction from outside towards inside of the vehicle
(Fig.7)
.
IMPORTANT:
The cut-away on the face of the Compressor
Sleeve (6) is positioned towards the bottom part of the
trailing arm face to accommodate any raised area of
casting. The Compressor Sleeve MUST fit squarely and
flush to the arm face and align centrally to the bore of the
arm, to ensure the new bush is not over-compressed when
entering the arm.
Slide Compressor Sleeve (6) over the bush with the arrow
on top and with the direction of the arrow pointing away
from Thrust Plate (4).
IMPORTANT:
Ensure the 'slot' of the bush
(Fig.8)
aligns
exactly under the arrow on Compressor Sleeve (6). The
bush is not visible during initial installation and the arrow
must act as your indicator for the correct positioning of the
bush. Align the complete assembly via the arrow ON TOP
of the Compressor Sleeve (6) with the paint mark made
earlier on the arm. Ensure the 'Slot' of the bush also aligns
under the arrow.
Assemble and fit all required parts as shown in the
Installation assembly sequence diagram
(Fig.7)
.
Counter-hold the Flange/Lock Nut combination whilst
turning the Force Nut Assembly to push the new bush
through Compressor Sleeve (6) and into its housing.
IMPORTANT:
Check 'Slot' of bush aligns with paint mark
made earlier on the arm.
Continue to tighten the Force Nut until the bush is correctly
installed with its metal portion protruding 2.5mm from
the face of the arm
