drive differential fluid

I have a 2001 Affinity and do not know the proper fluid for the drive wheel differential. This coach has a tag. Any advice? Where could I research? Thx.

Usually 75-90W. I personally went to a synthetic differential oil. I will not extend my change cycles, as the cost is so minimal. I just like the extra protection, and have been told by those that did 'before/after' infrared temp readings, that the differential run cooler.

If in doubt, call CC with your coach build number, and they should be able to tell you the exact differential you have in your coach. Go with what that manufacturer say's is the proper weight. (You might look to see if our documentation package includes this info.)

And good for you doing this. I've been so surprised over the years, by the number of owners that have never changed their differential fluids. Out of sight, out of mind!

Yes chassis manual is y=the place to go. Depending on the temp. range mine runs 80w-140. If you are going to be somewhere really cold down to -40 then it states to run 75w-140, lots of other weights to run and as stated synthetic would be better for most applications. Are you just changing it or adding cause it is low?
