Recommend weight for differential
Sorry normally I would search but typing "differential fluid" in the search engine opens an entire encylopedia and I am at work 
. Don't have the time to search during work hours.
So if someone would be kind enough just tell me what weight, that would be nice.

Usually one checks their owners manual which like most owners manuals for the past 50 years lists all fluid amounts and recommended specifications.
More details are available in the Factory Service Manual which is available free or for a max of $20 to download in *.pdf format.
The are only 3 common viscosity [weights] for diffs. 75w90 in synthetic is the most common but 75/80/90w140 is quite usable depending on the operating temperature.
At what operating temperature will your diff be operating at peak?
