These too are great responses. Many thanks! I was out of town yesterday with a friend at the junkyards. In the afternoon had "Black and Green" on jack stands and did some inspection of the front hubs and half-axles. (I had not read these newer responses yet, unfortunately.) But during inspection I saw that there really is no play in the front wheels that might suggest a hub bearing problem, but the hub, without the wheel on, did not make the grinding noise at low RPM in first gear (I wish I had tested at higher RPMs... forgot). Other things showed themselves: the CV boot on the passenger side half-axle is showing wear and there's a little grease leaking from the boot. The steering arm thing on the driver side is also leaking a little grease (nothing alarming in either case, but I'm gonna start collecting tools and reading-up on how to DIY replace the half axles with new).

That video is VERY helpful too. Big contrasts with my wheels.

So I'll get to these inspections today, after quality time with the family, and report back here.

Cheers!

I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
