13. If necessary, release the four bolts and remove the damper lower fixing bracket from the lower wishbone,
and the remaining bolt securing the anti-roll bar drop link bracket.
Anti-Roll Bar
14. At least one of the lower wishbones must be removed before the ARB may be withdrawn.
Release the anti-roll bar drop links from the ARB noting that the link assembly is symmetrical end to end.
Note that the drop link ball pin self locking nuts should be discarded and renewed for re-assembly. Re-
lease the two bolts securing each of the two ARB pivot clamps to the chassis brackets and withdraw the
anti-roll bar.
Reassembly
Re-assemble the suspension in reverse order to disassembly with the following notes:
- If the car suffers a suspension impact sufficient to damage a wheel rim, careful attention should be paid
to all related suspension components, and replacement parts fitted in any cases of doubt.
- Smear the shank of each pivot bolt with PBC grease to inhibit corrosion and facilitate subsequent servic-
ing, but do not allow grease contamination of the threads.
- Where bolts are threaded into captive nuts with no secondary locking mechanism, apply a suitable thread-
locking compound. If separate self-locking nuts are used, assess the locking torque and renew the nuts
in any case of doubt. The ARB drop link ball pin self locking nuts should always be renewed.
- Take care to match mark and refit the eccentric cam adjusters on the lower wishbone pivots in their original
settings to facilitate subsequent geometry checking and adjustment.
- Lubricate the rubber type anti-roll bar mountings with rubber grease on assembly.
- Refit the plastic bung into the steering arm counterbore to prevent corrosion of the ball joint fixing.
- The damper body is provided with three location grooves for the circlip retaining the spring lower seat.
Use the middle position for standard ride height setting. Use spring compressor clamps to assemble the
spring/damper/top mounting bracket (spring close coils lowermost), before fitting the complete assembly
to the car. Do not omit the spring top seat cushion.
- Pump the brake pedal to reposition the pads before driving the car.
The Service Schedule specifies that the security of the front and rear suspension is checked at each service.
For cars used on race tracks, or in similar conditions, suspension components and torque checks should be
carried out between sessions. This operation requires that all the principal suspension pivot bolts are torque
checked, noting the following points:
Where a bolt is tapped into a housing or weldnut, and relies on a thread locking compound for security, it
is important to appreciate that if the bolt is disturbed, the locking compound must be re-applied. The following
procedure should be adopted for all such fixings:
- Check the torque of the fixing.
- If the specified torque is attained without the fixing being disturbed (moving), take no further action.
- If the bolt moves, the locking action of the thread adhesive will have been compromised. Remove the
bolt completely, clean off all old adhesive using a wire brush and acetone, and apply new adhesive as
specified.
- Refit the bolt and tighten to the specified torque.
- If for any reason a bolt is found to have become loose, and the car has been operated for any period in
this condition, the bolt should be renewed as a standard precaution and related components carefully
inspected for hole ovality, undue stress or wear.
