Been a few years since I worked on a T-100, I remember pulling the wheel bearing cover but I dont remember if it was to pull off the rotor. We were dismantling a 4x4 T-100 with a salvage title that my buddy bought on E-Bay for $300, it had a low mileage (22k) running 3.0 that had the head/manifold recall done on it and my buddy needed the engine for his 4Runner.
Sorry I know that wasnt any help. But maybe you'll get a bump from someone that knows.
