|269_Bob||I just pulled 4,000 miles with my 2019 2500hd pulling a 10,000lb trailer after changing to 75w140 Valvoline full synthetic. No problems, no noise.|

Noisy differential after fluid change?
I replaced my differential fluid with Valvoline full synthetic oil and now my differential is noisy. It drives me nuts.
Should I just put AC Delco gear oil back in?
What oil are you using?
2015.5 GMC 3500 dually.
