I have a 95 f150 5.8 4x4 and I was wondering what weight of gear oil goes in the diffs. ( on my 03 there was a tsb from 75W-90 to 75W-140) I don't know if there was one on the 9th gens also. But it's a 3:55 limited slip if that makes a difference ( I know Motorcraft friction modifier ) I believe it's an 8.8 inch

My book says 80W-90 + 2oz friction modifier for the rear trac-lok axles and "4x4 gear oil" for the front. I think I used 80W-90 for both.
