<![CDATA[One of the current trends is the LCGC (Low Cost Green Car), one of the LCGC cars that people are interested in is the Toyota Calya. However, like other automotive products, the Toyota Calya did not escape the complaints of its users. The complaint that is often experienced by consumers is that the rear shock absorber of the Toyota Calya has collapsed and leaked, even though the age of this car is actually not even 3 years old and the kilometers have not reached 40 thousand kilometers. In this final project, the author conducts several analyzes of what only cause damage to the shock absorber Toyota Calya. In this study, load tests and measurements were carried out on several factors that caused damage to the Toyota Calya shock absorber. From the results of the study, it was found that the damage to the shock absorber occurred due to the fatigue material in the shock absorber seal, causing oil leakage in the rear shock absorber of the Toyota Calya. The cause of damage to the genuine Toyota Calya shock absorber is due to deformation of the shock absorber spring due to the spring not being able to reduce the force load that occurs when the vehicle is fully loaded, so that the shock absorber has a stroke (shortening) that exceeds the allowable standard limit. This causes the shock absorber to last longer. One solution to prevent the Toyota Calya shock absorber from sinking is to replace the shock absorber and spring with Kayaba's after-market products. Kayaba shock absorber has a larger diameter spring wire and a larger shock absorber diameter than the genuine Toyota Calya shock absorber. The second solution to prevent the Toyota Calya shock absorber from being damaged quickly is to reduce the full load on the vehicle. To avoid deflection or sinking symptoms in the rear shock absorber of the Toyota Calya is to reduce the full load on the vehicle. This of course will extend the life of the shock absorber, because a large spring deflection would result in damage faster in shock absorber components.]]>
