Rear wheel flew off
So, I bought the hubs I mentioned earlier. They are being sold by a Napa store in New York, so hopefully they are good quality. I bought 2 centric rotors and centric semi metallic pads. All in for $140, $1200 including wheels and tires. The hubs make me kinda concerned based on price, but I will let you know if they seem alright. I know centric is quality so i have no concern there.

The rear stuff is pretty cheap. It's the AWD front stuff that is expensive.
Out back, the parts are the same with every other G35 sedan and coupe on the road, so sheer scale of economics makes these parts cheap.
The passenger side wheel still spins. Would both sides seize or just 1? If I raise the rear and put it in gear and the opposite side turns, can I assume the rear diif is good. When it happened I was going uphill su I assumed the limited slip used the off wheel for power and thats how I got off the road.
If the bearing did seize up, it had to take some serious heat to do that. I would imagine you hear something leading up to that? usually before the bearings weld themselves togethet the race would gall up and that would be pretty rough to ride on.
Anyway, let us know what you find.
I was looking for a timken all in one hub and bearing, but i couldnt find any. I wanted a new hub since all 5 studs sheared. I will check these out to see if they have a good brand bearings.
The AWD front bearings, and rear bearings all usually come separate from the hub and must be pressed.
You can sometimes find a company who pairs them up pre-pressed, usually on Ebay or an off-brand company
Does the axle spin freely now? Any obvious noise, grinding, or play in the bearings on that side?
Also, out of curiosity - when was the last time you had the rear wheel off? Are the lug holes egged out now on the rim that flew off?
I only ask because I almost lost a wheel exiting the highway on one of my old cars - I also heard some squealing from the bearings while on the highway when the wheel was turned left or right, but it got really squirrely on the exit ramp, so I pulled over right away, and found three lugs sheared off. It turned out the two lugs that were left were really loose. In my situation, I have a feeling the lugs worked themselves loose, and caused the vibration and eventual shear of the studs...not sure if it was malicious intent (like someone tried to steal my wheels) or I forgot to retorque them. Just another theory for ya.

The Fixer, the reason I think something froze is the middle tread patterns on the tire are slick, like they were dragged. It havent had a chance to inspect it and wont until tomorrow. It is possible what you said happened as I am good about all maintainance except tires. I will go through a,set and never rotate them. That is the case with these tires. I use splined lugs and most thieves dont carry the tool for those. I will check the seat and hole for signs of attempted theft tomorrow. Thanks for the idea.
So, I did a tear down. Dropped spring buckets and removed half shafts. Bearing on both sides were fine. I put the car in drive and both hubs turned. Drained and refilled rear diff fluid and it looked and stunk like new. Drain magnet was perfectly clear. I inspected the sheared studs and found two have rust (next to eachother) where they sheared. I live in california and it has been dry since this happened. That, plus the other three were rust free leass me to believe the two lug nut were over tightened or just broke due to time and stress. The others must have broken from the wobbling. I should have done a better inspection at work. Pissed because the ebay guy said the part was the whole hub assembly, but it was just bearings. The picture for the listing shows hubs. Im gonna make him do right or file a complaint with ebay and paypal.
A search of the bearing model number reveals they are Timkin. Got both for $90, but still not happy with the seller misadvertising and false reply to my email.
