Wrangler Rubicon Thrust adjustment

Too consistent nagging complaining about the stability while straight running on Wrangler Rubicon obliged my heavy hip to move the action, it is simply called "Parent Baka Chanrin".
He must seek the way to solve the problem like this as I had been making efforts in this field.
The standard value of wheel base for 2-door Rubicon is 2458.72mm, 2456.0 for the right and 2457.0 were obtained promptly for actual scaling, so right side wheel base was extended as to the same value on the left side. Calculation shows 2.3 minutes angle value discrepancy, it is within the tolerance at all according to the European Traffic Safety Standard, but he complains, so I feel worse.
Consequently, upper and lower trailing arm hinge bush holding bolt and nut loosening method was invited. No blacked long hole adjustment was required, just moving the inner lace of bushes was enough to adjust this time.
Unpleasant handling as my son declared, ugly wandering with bad taste, relatively shorter wheel base and wide tread  enhances the tendency at all.
All the bad habit disappeared as if nothing had been happening, after adjusting with trifle attitude so effective to settle the crying child so calm.
I have realized the importance of "Zero Thrust Angle" in any vehicle not only for comfort but also for safety.
Vehicles in Japan Left side going for Auto mobiles, with Plus Thrust Angle is very dangerous because it will collide face to face if a driver might fall asleep, this truth and fact should be known by every driver.
