Differential oil

[Gadget]

How often should the Diff oil be changed? I'm not near a manual or I would look it up myself, also went thru the FAQ thread and nothing there either.

Every 65,000-75,000 miles

Every 30k if non synthetic and every 100k if synthetic

Is usage not a factor? thought it was more frequent for towing and heavy off road use?

I change diffs at 15k, it may be my paranoia but it's not like it's a big cost to change more often than "necessary"

I personally wouldn't exceede about 20k on Dino oil, 40k on synthetic.

However, for heavy use and frequent water crossings it doesn't hurt to change it more often. I use Dino oil because if my auto lockers and change it every 10k max, usually less. Lots of unavoidable water and mud around me tho.
