The rear suspension is a multi-link suspension,
which has been used for the previous models. The
layout of each arm and the rigidity balance of each
bushing have been rationalized to provide both
excellent steering stability and riding comfort.

INTRODUCTION TO REAR SUSPENSION DIAGNOSIS

M1341013100074

If the rear suspension is faulty, the vehicle will not run
straightforward or noise will occur. Incorrect wheel
alignment, malfunction of shock absorber, stabilizer
bar, coil spring, control arms or worn or out-of-
balance will cause these problems.
