My other task today was a second drain & refill on the Viggen's transmission... it's an '02 so *should* have had the "new" fluid, but I didn't want to bank on it so drained $30 worth of special gearbox juice and put another $30 worth of special gearbox juice in.

I think it was worth it - very much so. A 50 mile drive today and it was tangibly quieter and easier to shift. Like, actually really good to shift.

Next up... figuring out whether the rumbling up front is the tires or the wheel bearings. Hopefully the former!
