intermittent grinding noise after transmission replaced (1 Viewer)

[Eleanor]

My 1994 Cruiser (212k mi boat ramp rust bomb) began making a terrible quick grinding noise shortly after I had the transmission replaced. It seemed to only happen on deceleration initially. Then 2 or 3 times it did it for a much longer time (see video). My mechanic cannot replicate the noise and even with the helpful video, he doesn't seem to know where to begin. My brother seems to think the noise is related to the front axle worn pinion bearing and/or faulty pinion bearing preload since it appears there may be a leaking seal. I did have the front axle rebuilt several years and about 20k miles ago.
I'm not super mechanically savvy, so I'd appreciate any simply explained ideas!

Could be a front spindle bushing. There's a TSB about this moaning noise from front spindles, though I don't remember if it was for 80series.

Thank you Jim. Were you able to listen to the noise?
