Something is starting to smell sour here... <img src="/forums/images/graemlins/barf.gif" alt="" />

Definitely have a tech show you exactly what they replaced, have them explain why, and report back to us so we can see if you really are getting stiffed. How much was the "center differential" replacement?

I don't think there's any way they would call the front diff a "center" diff. Not on a Tacoma.

Give us all the information you can about what they did, how much it cost, and WHY. Then we can see for sure if you need to take up a formal complaint with that stealership or not! <img src="/forums/images/graemlins/kewl.gif" alt="" />
