With no load on the system could be just gear clash.. Have you driven it yet?

My hearing isn't that good. But what are you doing in 2 weeks? The annual Corvair College will have Corvair professors and students in the Portland area that can probably assist you with diagnosis.

> Looking for someone close to Cassville Missouri who has EM mechanical knowledge. As some know, I've got loud rear end noises that I can't pinpoint. Replaced rear axle bearing assemblies on passenger side and still have a noise coming from something. I'd prefer to have someone look at it before I throw more money at it and guessing. I'd even trailer it reasonably distance and pay for assistance. Wits end...Thanks..Steve

Springfield, MO area has several folks that are Corvair experts.
A look-up for fellow members of CORSA is available online at corvair.org.

I used to live around there, but moved many decades ago...

A friend is currenty moving from my area to Halltown, MO Send me a PM and I can perhaps help you contact him - he is a "top tier" mechanic. IMHO.

I took another video this morning. Me driving a mile down our blacktop road, turning around and driving back. No actual video, just sound. Phone was laying on back seat. You have to listen to entire clip but you can hear what I've been trying to describe in this "video". Thanks for all the help....Steve

Sounds like a bearing. Check the rear axle bearings, one at a time by jacking one side of car at a time. Unless it is a positraction!

Block the front tire and run in 3rd or 4th and see if one side is noisier than the other.

Drivers side...one I didn't replace, makes a similar sound. No noise from passenger side. Ordering new assembly today.... fingers crossed!

Thanks to this post, I was able to identify the noise. Got another axle assembly from California Corviars (FYI a WAY BETTER part than I got from Clarks, thanks Jeff) and my "noise" is history. Thanks to all who helped and gave a listen. smiling bouncing smiley
