Watched the mechanic take out the clutch today, and he didn't even want to measure the friction plates - they were chewed down nearly flat. He is suggesting to also replace clutch driven plates (metal rings between friction plates). He didn't measure them either but thinks they looked burned and are likely warped enough so it would be best to just replace them too.
Now, the point I need advice with, he also wants to discard "wave washers", parts 21471-17G00 and 21472-17G00. He says they act as a spring, and can make clutch easier to disengage, but also can prevent it from seating fully, if I understand him right. Crazy talk or good idea?
