Hey folks, having issues with my new clutch on my FJ60 and hoping to get some debugging help.
Namely, I feel a weird sensation through the clutch pedal during some actions. I feel a sort of pop (or a weak kickback) when doing one of: pushing the clutch down, coming off the clutch, or even sometimes when i have the clutch pushed down and just move the shifter out of neutral into a new gear. I think when the truck has warmed up it goes from some actions to most. It's really disconcerting. I think this might have happened a couple of times starting from a stop, and it has the result of feeling like the clutch has just released and I've slammed into gear. Worst it makes me feel reluctant to ride my clutch in the friction zone at all once I'm warmed up.
My leading theories after taking my inspection cover off: that the front surface of the throwout bearing is still dirty and might be catching oddly on the pressure plate (my rear main seal is definitely leaking, possibly my transmission too, the bell housing is all dirty). Maybe I can disconnect the clutch fork and wipe off the front of the throwout bearing. That, or maybe I have air in my clutch fluid lines and need to bleed them some more.
Secondary issue I have that might be related: I had to adjust my slave cylinder pushrod to be all the way out, and then adjust the clutch pedal beyond the FSM's pedal height adjustment measurement (instead of 7.13" it's over 8"), and the engagement point is still pretty low. I did get my flywheel re-machined and it doesn't look too off.
For background: I replaced my clutch two months ago with the Aisin CKT-032 kit, also got new OEM slave (adjustable pushrod) and master cylinders and hose that runs between the two. Had an issue for the first 300-400 miles/two months where the throwout bearing was squealing when in the friction zone (link), that's mostly gone away now.
