SUBARU Legacy BC7 LSi

Any problem caused by mechanical defect or error would not be solved before it is corrected or repaired fairly however long it is used with enduring inconveniences, better expectation, prayer, devotion nor curse would not take effect if any or many specific religions might be devoted. Just watching or waiting without taking any measures, especially correction and establishing in the wheel alignment and fundamental error in geometric construction in axle suspension mechanisms require tremendous efforts and precise concentrations with patience, so we do not get in other(even professionals) leaving to others.   
Describing like this, it is a shame to write that, considerable set back value was found in my lovely BC7 initial generation Legacy sedan US model, the discrepancy value prevent me from proceed to next step, so, measuring step only is the task today. Remembering the past, this is my selfish mistake to make it run to the right to cancel the left side run habit, but my later research proved that the measures to makeshift like this is nothing but more hustle than it is worth and the cheap trick is consumed by the caster action, self adjusting and correcting caster actions on both side, so to speak "Self steer".  As a matter of fact, it was not canceled in pieces, strange bad habit is illusory with glimpses changing the rate and sometimes even to the opposite direction depending on the speed ranges. It's a matter for regret that this car has been used in ill alignment condition as long as 130,000 km distance, also it was an unfortunate situation for this model. Now, I have made up my mind to secure this with all my efforts from now. Eliminations of Set back, lateral offset on front and rear main bars, swung rear end and establishing wheel alignment on the former geometric construction are the indispensable requirement to drive in comfortable condition, this is my principle in my automobile maintenance. It's a good opportunity to do that, because VW 1302 Super Beetle is absent from my garage because of getting face lift(body painting in the original color, Marina Blue).
Ground plane for measuring and adjusting the wheel alignment and constructive axle geometry was re-checked so carefully as not to have any regret, because the parallelism and flatness of ground surface is the key to rely on and the obtained datum in future are fully based on the critical plane, horizontal and also vertical directions. So, I cannot be too careful to ascertain the accuracy of the reliable plane repeatedly and occasionally.
