and its easy if you buy the $15 from harbor freight tool that sucks the stuff out, you dont even need ot take the cover off, i would take the cover off every 60,000 or so and completely clean it down with paint thinner, but if you change it every 20,000 you shjould be good
For $200 I'll come up and do it for you.....talk about bendmeover pricing.

Total cost ~$40 + $12 for a pound of Starbucks French roast beans. Or you can get industrious and do all your fluids while you have it up on jackstands.
I bought the car at 33k miles and took it to the dealer yesterday at 35,950 to get some last-minute warranty stuff done. One of the things I noticed when I had it on a lift was that the front diff. was slightly leaking (really just looked wet but never left a spot in my garage). So in warranty I wanted them to fix it before I realized that it should have been done long before that. They did the rear too under warranty.
They told me it was leaking probably because it had never been done before.
I don't tow with it and mostly use it on-road. I probably won't have the dealer do the diff. service again even if I don't end up doing it myself.

Well, I can see fluid on the shaft and the Fluid stain goes to the U joint. I asked the oil change guys (express lube or something) what was involved and the were very helpful and said parts weren't going to be that bad $$ wise..... just time consuming. Reseal the diff cover or buy a new one then remove the seal around the shaft.... and I think this is where the problem or trouble or time really would come in....
Sorry If my writing is ambiguous.... I'm at work and typing as quickly as possible
