Inconveniences

It's difficult to seek and to find out that's invisible. The same is said on wheel alignment and axle construction geometry. But actually feel some differences on steering reaction comparing the before and the after, then getting accustomed to the situation sooner or later. These challenge were repeated for these several years with a little improvement.

On BC7 SUBARU Legacy LSi US model, almost satisfied as I am, some dissatisfaction remains, straight running almost OK, compliance setting OK, hysteresis are adequately eliminated no ploblem but the transient of steering reaction is not favorable gaining harder reaction proportioning with the action angle.

This phenomena must be caused by ill setting on TOOT (Toe Out On Turn) in frontal axle geometry. And main reason of this inconvenience dues to the change of height 35mm low down, causing the destruction of the important 3 dimensional relation between Rack end point and tie rod end point.

The best way to solve this unpleasant problem is the replacement of suspension coil spring from GC8-GDB's to original ones. Strut upper mounts including rear ones must be replaced at the same time if this task may be performed. The genuine parts number would be checked by Minami Osaka Kishiwada SUBARU.

Working place in my lab room #2 lacks the thermal fuse on oil pressure control solenoid valve by shortening for emergency.

The temperature of solenoid coil had been risen by water pilling on printed circuitry board leading to circuitry shortening.

Thermal fuse 185 degree must be replace instead of shortening, otherwise #2 is free from breaking fire dangers.
