I can take some when i get home in about 3-4 hours. Could it be the tech drive making that sound even though the machine is not moving? I will see if i can record a decent quality video when i take the pictures. | ||

 Gene,
It sounds like motor bearings to me. After sitting for nearly 10 years in a shed the bearings are most likely all dried out. You should replace both the front and rear motor bearings.
It also just occurred to me that the brush roller bearings are probably shot as well. I would not continue to run it until you replace both the motor bearings and get a new brush roller and new rubber belt as it is most likely dried and cracked. | ||

I agree with sptyks' assessment. It's most likely the motor bearings. Don't run it again until you replace them. And good for you for bringing that beast back to life! It should give you many years of good service and should save you money in the long run--not to mention the environment--over what you'd spend on cheap plastivacs.

I've swapped the motors already, so once I put the G5 back together with the G4's motor in it tomorrow I will record the video. | ||

worn bearings sound primer-
ball bearings usually make a rumbling sound, & the sound may come and go, they can can also make a high pitched whine
sleeve bearing usually make a scraping sound

I know exactly the sound you're describing. I had a G4 that made the exact same noise. I remember it well because the girl I was living with at the time mocked it. I consulted my G series service manual. Under section 4 - Troubleshooting, #9. Squeal noise from motor on wind down. > Probable Cause > Rubber seal creeps on bearing plate eyelet. > Solution > Apply thin coat of T159 S grease to eyelet under rubber seal.
I can tell by listening that you have a lot more problems than that. I don't know if you've worked on a G series machine before or not, but they are a lot more complicated than pre-G series. If I hadn't had my service manual the first time I tried it I would probably been in trouble. Unless you just like taking on work intensive projects, I wouldn't bother. The newer machines are much nicer. I have a Ultimate G Diamond Edition with the newer transmission that doesn't groan. It's a much nicer machine than a G4 and the can be had reconditioned from that place in Utah for around $400.00 with all the attachments. By the time you get done fixing that thing properly you'll have nearly that much in parts. And that won't include your work. If you just want to do it for fun, OK. But personally it seems like pounding money down a rat hole. | ||
