Section CG
The primary purpose of camber is to achieve the maximum efficiency of the tyre under cornering loads and
body roll, with the specification closely allied to a particular wheel/tyre combination. The camber angle changes
with suspension travel, becoming more negative on bump, and should be measured only at the specified ride
height. Incorrect camber can result in handling deficiencies and excessive tyre wear.
Camber adjustment shim plates are fitted between the top wishbone ball joint plinth and the hub carrier.
Shims are available in 1 mm thickness.
Reducing the shim pack thickness will increase negative camber. Adding shims will reduce negative
camber.
A 1mm shim plate will alter camber by approximately 0.3°.
Before final assembly, coat the joint face between the steel shim plate and the alloy hub carrier with
Duralac MSDS anti-corrosive jointing compound (A111C6017), and assemble whilst the compound is still
tacky.
Apply Permabond A131 (A912E7034) to the threads of the two ball joint plinth fixing bolts, and torque
tighten to 45 Nm.
DE.3 - SUSPENSION DISASSEMBLY/ASSEMBLY
The suspension may be disassembled without the use of any special tools other than a spring compressor
if the spring is to be removed from the damper unit. Removal of the driveshaft from the hub will usually result
in separation of the hub bearing two part inner race, with likely damage to the integral seal. If the hub or hub
carrier is being removed for reasons other than for hub bearing replacement, the inboard driveshaft should be
removed from the transmission, and the complete driveshaft assembly retained with the hub carrier and hub.
With the car on a wheel free lift and with the rear wheels removed:
1. If fitted, remove the engine bay undertray to provide access to the lower wishbone front pivot.
2. Remove the two bolts securing the brake caliper to the mounting plate, release the routing clips securing
the flexible hose and parking brake cable, and support the caliper aside without straining the brake hose.
Release the single retaining screw, and remove the brake disc from the hub.
3. Release the bolt securing the outer end of the toe link to the hub carrier, noting and retaining the shim
washers fitted between the ball pin and conical spacer.
4. Remove the two bolts securing the top swivel joint plinth to the hub carrier, noting and retaining the
camber adjustment shim pack.
5. The inboard C.V. joint is retained in the transmission by a rounded section circlip, and may be removed
using a special wedge tool T000T1276, or by applying a shock pull to the C.V. joint body using a slide
hammer with a forked end.
