Don,
It all depends on how one treats the beast. I have driven over 130K on
the same clutch that came with the used vehicle that had 115K when I
bought it and sold it with the same clutch. All I had to do was adjust
it twice.
I have sold parts for over 15 years. I have seen parts fail due to
improper installation, abuse by the owner, flat worn out due to it's
life span and sometimes because of a manufacturing defect.
Then again I sold the same part (rear axle shaft for a CJ-5 jeep) every
two to four weeks to a teenager that became quite accomplished at
replacing the axle shaft. I later found out that he was racing the jeep
with quite large oversized tires. I guess that he was winning!
