changing axle fluid

My maint. manual for our '04 Dodge Durango calls for the axle fluid to be changed at 30.000mi. I had it done by a shop at 15,000mi as it called for, but it was more money than I thought.
Can I do this myself? I did not see a drain plug for the fluid, but there is a rubber boot for the fill hole. I have a vacuum pump in case I had to pump out the fluid.
How difficult is this procedure?

Thanks.

carr,
I'm not familiar with your Durango but on my '89 Mustang, the only way to drain the axle is to remove the cover. Then you replace the cover and refill from a hole on the top of the axle. Your's might be the same.

They do make aftermarket covers with a drain plug!

most likely you have to take off the cover and it is alot cheaper doing it yourself

I'm wondering why MOPAR requires such an overkill on preventive maintenance. There are millions of vehicles on the road that have never had the differential gear oil changed and rear end failures are fairly rare.

I'm with tow guy on this....I'd not do anything to it until 100k.
The manufacturer writes these "service intervals" to keep their garages open....and many people follow them to the letter, $$$ for the garage. Now if you have a gasket or seal leaking, different story of course.

And if you have a 100,000 mile warranty and you have a seal leak at 60,000 and you did not follow the manufacturer recommendation to change the oil at 50k or whenever, then you might get some grief over the warranty coverage.

But I do agree...it is a rare failure, and if it does occur will usually do so in the first 5k.

It is a rare failure but when it does fail it is not a cheap fix. when I did mine the first time I drilled a hole in the bottom and tapped for a flush drain plug, just like the old days, now just pull the plug.

Just curious, but how much is the dealer charging for the service? I'll wager it's >$100.

I had it done at 15,000mi. $164; I told the shop I had a mini-stroke.

Fluid

I tow an RV and I don't service my differantial fluid. I check it and thats about it. At 100K I will probably replace the fluid. The fluid is like 90W and last a long time unless you have a leak.

Leo,
15,000 miles? Are you sure that mini stroke didn't affect the way you look at numbers? Maybe to you, the odometer looked like 150,000 miles, eh?

Why would you change your diff fluid at 15,000 miles? The car's not even broken in yet!

Think the diff fluid's been changed once on my wrecker and it's got 460,000 miles on it.

$164??? Lets see, $15-20 for the oil, $5 disposal fee, $10 shop supplies, $10 for taxes; that leaves about $120 for labor. Must have taken them an hour and a half to do. And people wonder why I have such disdain for dealers.
