I've got an FBO 2002 c5 base with a differential whine problem diagnosed by my mechanic. He's recommended essentially a full diff/trans rebuild (as they're one whole assembly usually), and recommended I ship it out to a facility in Texas as he can replace it but doesn't do rebuilds. My guy has good pricing and keeps it pretty real about what's going on, but I'm wondering if there would be any better options price-wise or if I should bite the bullet and get it done. Car's pushing about 400whp and has about 93k miles on it as well
