At this point, id imagine its to far gone to clean. I have had good results myself with all brand clutches BESIDES centerforce. They seem to wear out extremely fast on these toyotas. I dont know if its the tiny engine, the gears in the trans, or the way we drive these trucks, but I swear I hear of more of those cf clutches going bad than any other.

Whaever your pocket can afford is what id go with.
