What weight is required in the diffs? Switching to synthetic.

Thanks

 

Nevermind, it appears in the manual that these came from the factory with synthetic in them. Thanks.

 

So depending if you live in a hot area you can also go to the 85W/140 gear oil for some extrea protection, and believe me our Rover diff's need all the care they can get. You can, here again if you are in a hotter area use the same 85W/140 in your t/case.
