Bondtech LGX extruder binding

I have two LGX extruders. One is on my VCore 3.0 500 that has worked great with no issues even when the enclosure gets a little toasty (~70c).

However, I have another extruder that is brand new that I was upgrading my Pruda Bear with. Just finished FINALLY getting around to the Prusa 2.5'ish to Prusa Bear upgrade and moved to a HeroMe Gen 7 carriage and Revo hotend. Got everything going and was pushing plastic getting ready for test prints.

I noticed that the printer would stop extruding after a short amount of time. Chased several normal problem solutions (bump up temp, bump up current, slow things down) and nothing seemed to work. Took the extruder apart and lubricated everything. By hand it seemed to function just fine. Put it back in the system and back to not extruding again. Took it apart again and put it back together. Started testing movement by hand again and I noticed that there is a point where the gears seem to bind. Fairly repeatable at the same spot. Seems more related to the large gear rather than the stepper spur gear.

Has anyone run across this and found a solution?

I have a new LGX on the way to in theory get the Bear up and running. Just wondering if the misbehaving unit is salvageable.
