2008 Forester NA. Iintermittant wheel or driveline vibration, seems to be up front.
I've previously replaced front wheel bearings/seals. Swapped axles around. One new axle at some point.
Seems to heat up randomly on highway and start grinding faintly, increasing, until speed changes.
It used to alarm me. Now I just slow down and find a speed where the noise remains constant, not getting louder or changing.
After stopping it seems to cool down and reset.
Every few days it happens.
I think I know why it happens on this year and model and not on my 1999 ForesterNA.
