Mine begins a bit of reverse "grinding" when adjustment is off!!
You mention the clutch pedal is too close to the floor....Try adjusting to engage about 1" to 2" away from the floor and I think you will find the answer??
I have had a tough time with heat deterioration of clutch cables and have driven home a few times with no clutch...quite a challenge in traffic!!
I recently installed a new cable with insulation...Hope it works!!
Good Luck!!
