LR3/Disco 3
The upper control arm locates in brackets on the upper surface of each chassis side member. The upper control arm
assembly comprises the control arm and two bushes. The upper control arm is a pressed steel fabrication. Its outer end
has two brackets with slotted holes which locate the upper ball joint of the knuckle. The ball joint is secured in the upper
control arm with a cam bolt, eccentric washer and a self-locking nut. The cam bolt and the eccentric washer allow for the
adjustment of the wheel camber.
Two fabricated tubular housings provide the location for the forward and rearward bushes. The bushes, which are
pressed into the housings, locate between brackets on the chassis side members and are secured with bolts and caged
nuts through metal inserts in the centre of the bushes.
