So this new to me 99 impreza L,(with 147k miles on odo) may not have a functional AWD? When I test drove it, I did a full turned to one side, tight , figure 8 on pavement & could hear and feel wheels scuffing. This was the reason for getting a sub in the first place. (my road is not plowed)

.

On Edit; my buddy who worked at dealer told when I change fluid in dif, to add the additive, like the old LSD on American cars. My owners manual does not mention anywhere to do this.???? Who's right? The additive is slippery-er right? This kept the old LSD from chattering when making turns, right?

Yeah - the unit itself is tiny (like maybe 3" in diameter) and is all welded together with the fluid inside. Very similar to the 5MT center VC's.

yeah, it's buried in the middle of the diff too. Just as practical to swap it out - or get a different style, diff I guess.
