FRONT SUSPENSION DIAGNOSIS
INTRODUCTION TO FRONT SUSPENSION DIAGNOSIS
M1332009000281
If the front suspension is faulty, the vehicle will not
run straightforward or noise will occur. Incorrect
wheel alignment, malfunction of strut assembly, sta-
bilizer bar, coil spring, or worn or out-of-balance tires
can cause these problems.
