OK...I've searched and searched and am more confused than ever. Is there an equivalent out there?
I bought (last fall) a 2001 K2500 Suburban w/the 8.1l V8 and the locking diff rear. It now has 110,000 miles on it. Since I tow a fair amount with it I was going to change the rear diff fluid before a long trip next month. The previous owner had the rear serviced at the dealership using the expensive grape juice at 92k miles.
I called the dealer asking for the cost of the diff fluid (old part #12378261, new part #89021677) and it's $35/quart(!) Is there a consensus on an equivalent?
