Thank you for the donation and our apologies for the delay in answering. Seems it is the story about the fish that got through. ;)
There was a Technical Sevice Bulletin on rear axle noise repairs with a improved parts kit.
It deals with limited warranty and I guess your vehicle must be out of warranty.
This repair is a specialised repair and I would recommend it to be done by someone who knows the job so the dealer is the best place.
No information is available on the kit cost but a break down of the items is rather costly, more than $ 1000 in parts.
I would suggest you get more info from your dealer.
Did you do the bearing replacements at the dealer? If yes you could ask them for a goodwill repair, ( at least part of it is better than nothing ) as they did not diagnose the noise correctly resulting in you having to replace the wheel bearings.
This type of axle noise would not cause the differential to break down suddenly and is only caused by improper adjustment or some wear of the pinion and crown wheel. It is not going to fail without a warning. At least the noise level would be unbearable before it would give way.
