Shaken and Self Inspection Part 1B

In the last article we had a brief introduction to Shaken and why cars that have recently passed Shaken are good candidates for export.  The last article also introduced the Shaken Self-Inspection also started going in depth on the items the owner is required to check on the Shaken Self-Inspection before even taking the vehicle to the Shaken Station.  This article will finish the in depth look at the Shaken Self-Inspection.  Japanese auto owners often have a mechanic do the Shaken Self-Inspection, which means that most vehicles are fully maintained and inspected by a professional at least once every two years.  If you are looking for a well maintained JDM vehicle, Japan Car Direct can source one for you direct form dealer auctions and dealer lots across Japan.

The number and depth of the parts that need to be inspected keep the average vehicle in Japan in top working condition and maximize safety for the driver, passengers and others on the road.  However, because most Japanese people lack the place or skill to be able to do the inspections on their own, they elect to have their vehicles looked at and inspected by a mechanic every two years before Shaken.  We can locate a vehicle for you that has recently passed Shaken.

In Part 2, we will cover the actual Shaken Test!
