VW Golf 7 GTI axle adjustment again

VW Golf 7 GTI is a mischievous vehicle, because she changes wheel alignment and axle construction whimsically. Although tried I adjustment 3 times, the condition does become stable. Probably, 5 years use with some different physical condition must be the reason. Continuous stimulation to the specific direction on the bushes scattered everywhere in the axle construction is the reason.
As we know, rubber material that has elastic physical property remains permanent distortion and rebound back gradually, in another word, so to speak Hysteresis phenomena.
So, long used vehicles have some difficulty to establish Zero Thrust condition.
As a conclusion, vehicles with rubber bushes in axle construction require periodical checking and adjusting.

Useless effort



Toe-in 10 minutes & Zero Thrust condition had been established in TOYOTA Caldina AZT-241W already, and no complaint in driving feel at all. But, only a problem to be remembered has been in my mind, right rear arm had a fixation on the outer thread because of rusting as shown. Incapable reuse feeling of premonition obliged me to go into the market to obtain. Replacement parts were prepared from Yahoo Auction prior to the correcting procedure, they were disassembled from 4WS model same parts as 2WD with common parts.
After disassembling the right lower arm I have realized that the fixation had been done by the manufacturer intentionally, a paunching pressure mark on the long nut revealed the fact, the criminal fixation was not rust but mechanical lock.
"Parturiunt montes, nascetur ridiculus mus."
It took me half a day to disassemble the rear axle and reassemble it as it was including thrust adjustment.
I have realized that I'm watched and checked by the neighbors, they came to have a talk with me while I was under the car.
Basic construction of this part, lower arm shows the quality of manufacturing with precision by TOYOTA.

Unprecedented loss

It's nothing but disastrous sadness to know the fire broke out in Paris, over 800 years old Cathedral was lost last night, my indispensable memory 30 years ago would never come back again, people in the news are all dark filled with sadness and disappointment.
I hope it would be build up fairly again ASAP.

Selection requirement

No similarity with another former works.
No common work.
Permissible what it is.
Composition.
Illumination.
Eye-friendly.
No artificial Hail.

Upper items are my judgment on the pictures in the contest.
Remember that there are no fundamental ones such as out-focusing, camera shake or subject blur.
Composition is the most important item among them, the energy of the subject must be surely printed on the picture.

New year began



Good wheel alignment and better combustion in VW 1302 Air-cooled Beetle invited me to sightseeing driving to Kameoka yesterday. Zero Thrust establishment makes me feel continue more and more. AD motor has enough advantage to be in the usual traffic flow with no inferiority complex.
All the Cherry Blossom are in full bloom as the best in the Western part of Kyoto. Though the recording camera is old as ten years, it has enough capability to play as a matter of fact, with surprise I recommend the great development of the micro- technology in this field.

Test driving in full bloom







Warm and fine climate condition took me out for a test driving yesterday. The purpose of driving was to know the alternations after establishing the wheel alignment and axle construction. Some used history of tire treads in a specific condition so to speak "Tire Conicity" affects on the steering reaction at the beginning, but the tendency changed into stable condition gradually.
Now is the season for Cherry Blossom, so several photos were recorded on the way.
