Thrust in SXE10 Altezza

I have realized after establishing zero thrust in SXE10 TOYOTA Altezza that even a slight value of wheel alignment discrepancy as to 0,21 minutes(12,90 seconds angle value) causes some indescribably unpleasant steering feeling, le the thrust angle has much to do with the straightness of the vehicle. Hmmm---, there exist several difficulties, for example, rubber bushes scattered everywhere in the axle construction designing for preventing noise and vibration from the ground and motor crankshaft knocking stimulation, yes, these materials has inevitable physical properties, changeable permanent elastic strain, viscoelastic hysteresis. They are all the criminals that prevent us to adjust and set up the axle constructive geometry and wheel alignment in the critically precise condition. It goes without writing there that the tires has also much to do with the upper condition, because they cause some uneven polarized wear according to use in unfavorably bad environmental condition. So, we should check and correct periodically the axle constructive condition if we desire to drive your vehicle in comfort, the importance is the wheel alignment.
