I recently noticed a 1997 Landcruiser with the front drive shaft out of phase. The marks were lined up but the shaft was not phased. I've always heard that drive shafts are supposed to be phased. Thought someone had put it back together wrong but found the same thing on my '96. Toyota says that they cannot explain it but that they all came that way. So first a quick survey to see if anyone has a properly phased front drive shaft and second why do they come this way? What is the logic behind it? Something with the viscous coupling system? Thannks ??? ???
