There is not a “ridge” per say to accept the crush sleeve. There is a steel sleeve inside the knob that provides the force to hold the crush sleeve tight. That steel sleeve is about 1/4 in inside the knob. Two issues I think:
-Maybe the shift lever is not clean enough: Next time I’ll give it a slight sanding to remove any leftover glue residues from the PO’s previous leather knob install
-as it requires very high force to go in, maybe there is a tendency for the knob to become slightly angled applying pressure on the plastic portion the protrudes past the metal sleeve, that would initiate the crack that propagates itself past the steel sleeve, so the knob can move on the tightly held sleeve.
So I’ll wait until my pride has recovered and try another knob. Or I’m tempted to go to the wood type one but I kind of like the stock look…
