The question, pulled from the end: Even if the differential was suppose to get 80w-90, why would it be so noisy all of a sudden?
Bit of an odd frustrating day I had, needed the gear oil changed on my rear axle. Having priced things out, I took it in to a lube shop, they look up the vin which indicates 75w-140, the second tag is missing though and so they put 80w-90 in the axle. After three hours of back and forth between myself, the lube shop, and Ford who verified over the phone that it was in fact a torsen, they (presumably) drained the differential and (I can only hope) filled it back up with 75w-140...
Driving the truck home however, the differential made one horrible whining sound. I plan on opening up fill plug to see if they didn't just empty it and send me on my way but the question remains..... Even if the differential was suppose to get 80w-90, why would it be so noisy all of a sudden? Is this normal? Should this be cause for concern?
