Narrative:

Cleared RIIVR2 arrival to riivr then ILS runway 25L to lax. At or near dynmo at about 8500 ft on the VNAV generated glidepath we experienced an encounter with wake turbulence from the B767 ahead. TCAS showed the B767 ahead 8 miles and 2500 ft below us. Wind at altitude was 11 KTS tailwind coming from about 10 degrees off the left side of the tail. 8 to 10 seconds of thumping and hard wing rocking -- probably no more than 30 degrees bank angle. Mostly discomfort; not so violent that we thought the plane would come apart.
