Question 5 a. A four-wheel drive (4WD) vehicle was sent to the workshop after involving in a minor collision. After the evaluation, this vehicle experiences some problems with the front and rear wheels which cause the shimmy vibration. Further checking found both front and rear tire conditions still in good condition which indicate the problems may be due to another issue. i. Suggest several problems based on the definition of shimmy vibration and by considering the above findings. ii. Based on one of your answers in question a. (i), explain the relevant method and step-by-step procedures for correction with the assistance of relevant diagrams. Question 5 b. In a different case, during the vehicle test drive after an adjustment of the rear camber with an excessive negative camber, it is found that the rear side of the vehicle vibrates excessively after driving several kilometers. Later it is found that the shims used for the adjustment have been damaged. i. Suggest several root causes that are suspected based on the findings above ii. Explain the correct methods in correcting the rear camber (negative camber) using a shim. Explain with the aids of relevant diagrams.

Question 5
a. A four-wheel drive (4WD) vehicle was sent to the workshop after involving in a minor
collision. After the evaluation, this vehicle experiences some problems with the front and
rear wheels which cause the shimmy vibration. Further checking found both front and
rear tire conditions still in good condition which indicate the problems may be due to
another issue.
i.
Suggest several problems based on the definition of shimmy vibration and by
considering the above findings.
ii.
Based on one of your answers in question a. (i), explain the relevant method and
step-by-step procedures for correction with the assistance of relevant diagrams.
Question 5
b. In a different case, during the vehicle test drive after an adjustment of the rear camber
with an excessive negative camber, it is found that the rear side of the vehicle vibrates
excessively after driving several kilometers. Later it is found that the shims used for the
adjustment have been damaged.
i. Suggest several root causes that are suspected based on the findings above
11.
Explain the correct methods in correcting the rear camber (negative camber) using
a shim. Explain with the aids of relevant diagrams.
