Looks like I have a very intermittent squeal from the pilot bearing. May wait till it gets a bit more repeatable / frequent but am reading up on parts alternatives and what R&R involves.

A common piece of advice is to replace the clutch, PP, and throwout/release bearing when everything is apart. With only 13K miles the clutch action feels fine and I am loathe to replace it unless it really looks bad upon removal. But the TOB may be a good idea.

Not sure where to find a new TOB though! Jerry does not carry it. Rockauto and O'Reilly both list the AC Delco 614018 which seems to have the correct inside dia for the black label ZFs but sure doesn't look like the ZR-1 TOBs that I have seen.

Any ideas?

Edit: my car is a 1991.

TIA.
