We always make it a rule to check our clutch cable sleeve and
boots whenever we change a clutch cable for two reasons: 1)
You're already there, why not? and 2) A bad clutch cable sleeve
can lead to jitters in your car when letting off your clutch.
It's also never a bad idea to make sure your wing nut is looking
good when you change your clutch cable, when one gets
cross-threaded you are running the risk of it loosening up and
suddenly you have no clutch.
