GENERAL DESCRIPTION
M1341000100234
This is a multi-link type double wishbone indepen-
dent rear suspension. Because the left and right
wheels move independently with almost no change
in tire posture, the tires contact the ground firmly,
providing excellent steering stability as well as
improved riding comfort.

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 out-of-balance tires
can cause these problems.
