I have a 2002 tundra. Because the previous owner didn't know the meaning of taking care of vehicles, both my front and rear differentials have hit the fan. Personally, i don't know much about it, but my mechanic (who i trust and has worked on my familys vehicles for the past 10 years) told my i need a complete rebuild for the front and back. According to him, the only place he could find the parts is the toyota dealership, and they want over $3200 for all the parts! Does anyone have any ideas for an alternative? I live in Alaska, and used parts are not very popular.
