Hi Subi friends, I have a question about which I still did not find an answer. And I am not sure if my 96 Legacy BD4 has permanent or switched on four wheel. When there was snow in the winter I tried it out and especially when starting up or at low speeds when the front wheels were looking for grip went after a second a slight jerk through the car and I suddenly had a pure grip again until the next stop. I would like the four wheel I also noticed on my TSN 348 computers that only Subaru Legacy STH stands for Subaru Legacy. At 349 but Subaru Legacy STH 4WD. The same is true of 350 and at 351 for a combo. I always thought the BG would have been permanent, so I’m completely confused now what that means. I was already stupid and dubious but couldn’t find any clarity about Subaru’s four-wheel system. Wü I’d be happy if someone could bring light to the dark.
