| - 8 - FRONT SUSPENSION. See Ex.S.408-11. Independent front wheel suspension. The upper control arm is attached at its end to the shock absorber camshaft. The lower control is pivoted at its ends on a solid shaft attached to the underside of the frame front crossmember. The chassis coil springs are supported at their lower ends in sheet metal seats, bolted to the lower control arms, and the upper end seats in the frame front crossmember. Rubber Bumpers are provided to limit travel. To provide more control of body roll, a front end stabiliser is used in conjunction with near side stabiliser. The front stabiliser is mounted in rubber on the frame ahead of the front springs with "Wahl" type connecting links from the stabiliser bar to the coil spring seat on the lower control arms. BACK AXLE. See Ex.S.412. FRAME. The frame consists of side rails in 9 SWG. (.144) material and a cruciform torque member of 11 S.W.G. (.116). The Cruciform torque member is made as an I member and starts from rear of engine and extends to kick up over the back axle. The cruciform is tied up to the side channels by 3 gusset plates on each side. The rear cross member is 9 SWG. (.144) thick and stiffened by a short pressed plate at each end from top of member to underside of side channels. | ||
