Steering Swivel Joints

The steering swivel joint housed in the outboard end of both the top and bottom wishbones, uses a steel
ball pin located in a synthetic spherical bearing cup pressed into the wishbone and retained by a swaging op-
eration. The joint requires no maintenance other than a visual inspection of the dust gaiter, and is replaceable
only as an integral part of the wishbone assembly.

Damper Pivots

The lower eye of the damper is fitted with a zero compliance, through bolted, spherical joint which may
be replaced using suitable press tools. The upper eye houses a bonded rubber bush, with a steel outer sleeve
and an alloy inner sleeve. The bush may be replaced using suitable press tools.
CK.4 - ANTI-ROLL BAR
The tubular steel anti-roll bar is mounted beneath the front subframe in rubber bushes retained by extruded
alloy clamps. One clamp secures the bar at each side to a bolt fixed, alloy extrusion, bridging the chassis drop
towers for the lower wishbone front and rear pivots. Each end of the bar loops upwards through the lower
wishbone and uses a short ball jointed drop link and forged steel bracket to connect to the rear leg of the lower
wishbone. At each side, a washer crimped to the bar, bears against the inboard end of the chassis mounting
bush to provide lateral location of the bar.
The drop link ball joints require no maintenance, and are replaceable only as part of the drop link as-
sembly. The chassis mounted bushes are lubricated with rubber grease on assembly, but require no routine
maintenance.
