2D – 2 REAR SUSPENSION
DAEWOO M-150 BL2
DESCRIPTION AND OPERATION
REAR SUSPENSION
The rear suspension consists of an axle with trailing
arms and a lateral rod, two coil springs, two shock ab-
sorbers, two upper spring seats, and two bump stop-pers. The axle structure maintains the relationship of the
wheels to the body.
Each coil spring is retained between a seat in the under-
body and a seat welded to the top of the rear axle.
