98 4runner Limited - Growl in front end, diff internals?

Hey everyone,

I have a craigslist nightmare vehicle in the shop today, a 98' Toyota 4runner Limited V6. Runs and drives fine, but it's got a heck of a growl in the front end over 15mph. We removed the diff and found that when it was turned it had some vibration and a ton of noise. Disassembled it and found it to be full of metal flake, and it appears the spider gears are worn and causing a good lot of the noise. The bearings seem to be alright, but I'm planning to replace those anyway while we're inside, due to the amount of metal in the fluid.

My questions are:
1. Is this a common failure?
2. Where can I purchase spider gears? Most places don't seem to list them.
3. Is there a rebuild kit that includes bearings and spider gears so I can make one part order and run with it?

Any help is appreciated....

Bill S.
