2007 FJ Cruiser new clutch

Maintenance/Repairs

I just had the clutch replaced on my FJ Cruiser, and the clutch pedal “grinds” a bit at the very bottom when pressing, and the same thing at the very bottom when releasing. I’ve never felt a clutch not be smooth at the bottom, when it engages. They can’t look at it again for another week, and it works, as I am able to shift and accelerate again, but I can feel the “shaking” in my foot and calf when driving. Does it just need an adjustment, or could this be something more? They did have to turn the fly-wheel as well.
