ok so i changed the clutch on the xterra with a few weird things going on. First of all. My starter makes a low grinding noise when starting up. I must inform that i put a new flywheel in as i did the project. I noticed the flywheels look different on the teeth ever so slightly but everything else is the same. Also my clutch pedal is pretty soft now. The biting zone is about the same but it is pretty soft before i have the clutch pedal hitting the bite zone. Meaning from the floor to the bite zone. It works wonderfully now though other than that. Shifting is smooth and launches and shifts are just fine. PLZ help. 2001 nissan xterra 120k miles.
