I think I got a great deal on the t case and diff changes. Isuzu in Belleville told me $149.95 for the diffs and $129.95 for the tc oil change. I got it all done for $154.00 in Butler. I ALWAYS ask what it will cost before they do anything because I can always take it somewhere else if they're gonna try to rip me off. It's amazing how people take advantage.
