One important goal of auto services consists in the correct prediction of replacement moment for each spare part. Starting by the parts sales analysis from AutoHaus Huber Sibiu, we studied the operational reliability at Opel cars in order to forecast their failure. Analyzing 3358 repaired cars during 12.01.2009 รท 31.01.2011 revealed that tie rods and dampers must be replaced quite early, to about 5 years. For increasing the reliability we propose an optimal design solution of the suspension system that finds parameters of stability and comfort under different exploiting conditions minimizing the discomfort during movement. Because the description of mathematical model, of the road profiles, of the optimizations techniques and of the integrating software applications represents extensive information that cannot be exhibited in a single article, in this paper we analyze the reliability of the suspension system, we provide software details and graphical results regarding different implemented road profiles.
