When removing or refitting the top link, it will be necess-ary to compress the road spring to detach the top link from the top of the spring turret. A special tool is avail-able for this purpose (see Section 5), the use of a Jack Is not recommended.
To remove and refit
1. Remove the shock absorber, see under “Shock Absorber — To remove and refit”.
2. Fit the spring compressor In place of the shock absorber and compress the road spring, the road spring should be compressed until the bottom link Is In the horizontal position. This relieves the tension on the swivel bearings and fulcrum pin attachment bolts.

4. Support the stub axle and hub assembly by positioning a stand under the hub.
5. Remove the top wishbone link and shims, identifying the position of any short alignment shims, by with-drawing two bolts and washers from the attachment plate.
6. Refitting Is the reverse of the removal sequence but particular attention must be given to the following:
|
(i) Ensure that all shims are returned to their original positions.
(ii) The nut on the swivel bearing and the two fulcrum pin bolts are tightened to the torque given in the “General Data Section”.
(iii) When a new replacement top wishbone link is fitted, the two nuts on the ends of the fulcrum pin must only be tightened when the weight of the car is on the roadwheels and a full front suspension check is carried out.
