We have received results of test of our samples to taxi company number 2 (CH01L and CH01R – for Chevrolet Epica). The drive shafts were replaced after 27,000km. The taxi company told us that this is a poor result and considered a failure.
We think that it is the same issue that plagued the last shipment of Sonata driveshafts, ie vibration at certain speeds.
I have proposed to the taxi company number 2 that we will send them an improved version. However they have requested us to send them a stress test report first. I have written to SSL to check if they can do such a stress test.
