Differential
As stupid as this might sound, I have a question regarding the differential oil grade for my 88 Bronco II. Recently I've changed rear bearings. They had over 400,000 km on them. Now I have to refill my diff, but I can not find anywhere what gear oil to put it in. Before I had this done at varous shops. Now I get different replays from them. Owner's manual does not say anything and my Hayes manual is not helpful either.
Thanks
Tom
P.S. the diff is a bit loose too, should I put something thicker than recommanded? is 80w90 okay?
