As for the eccentric slave cylinder, if the clutch pedal is sloppy/weak, doesn't spring back up, no pressure felt when depressed/stepped on & theres leaking, it has to be replaced.
While the transmission is down/pulled out from vehicle, might as well have the age/conditions of pressure plate, disc, throw out bearing checked or replace if it shows needs replacing. See the condition of the flywheel too.
Check the CV axles & their splines. If splines look wornout, chipped, broken, filed down or filed smooth, replace. Majority of CV axles last several yrs when vehicle isn't driven like a F&F or Need For Speed (NFS).
Have the transmission fluid/gear changed out if it's neglected, unmaintained, not changed. Don't fall for the "Closed for life, Do not service, No service need" transmission wives tales. That's a scare tactic to have owners come in & either trade in or buy new cars. It also puts 100% blame on grown adults that should've known better & hold them accountable especially if vehicle/s are under warranty & owners want warranty repairs. When warranty expires, then owners can do whatever they want to their cars. Can't complain when fluids aren't changed, poor lack of proper maintenance or "I'll do it later, next week"
All I.C.E. vehicles need their fluids, oils changed due to wear tear, thermal breakdown, metal shavings, thickening, heat cycles, extreme heat & friction.
Also, don't fall for & believe those 1 time a yr engine oil changes unless you drive 1 time every yr. Change your vehicles fluids/oils.
