I am new to the forum and have been looking through it for some time. I have been hearing a slight grinding sound and thought it was a front wheel bearing. After reading through some threads I decided to take it to the mechanic to check the front differential oil and my heart dropped when i noticed the oil glittering from very small metal shavings. I am hoping someone can tell me where can i find a rebuild kit for the front differential for a 2005 V6. Differential p/n is 902-409-508k. Please help the dealer is asking $3100 for one and that is after a discount from a friend of mine that works in the parts department. I really need some help.
