Just got back from canping and my rear end started humming about 20 miles from home. Left the camper at a friends place and limped home real slow. I tow a 24' camper (4000lbs) not even close to my limit of 6500lbs. I am very unhappy with this car right now. I did the fluid upgrade about a month ago. Question is do they just replace it with the same junk or with an upgrade. If they replace it with the same junk, I have a 04 Armada for sale.
Sad thing is I just bought a 05 Titan truck.

They changed the fluid spec and the dif cover in '05. Your old rear end may have been shot from the old stuff. This is the first Armada rear I've heard going though and a lot of people tow much more than you on a regular basis. I'd get the new one and chaulk it up to a fluke. The new Titan rears aren't having the problems now either.

This is a perfect example of why I am petrified of dealer service departments. The techs are forced to play "beat the clock" and no one has the time nor the personnel to check their work. You don't know for sure that; (A) they put the upgraded oil in or (B) they put the right amount in, if any at all. This is the first Armada rearend I have heard of failing, I would be highly suspicious of your rearend oil service.
My last GM truck used the power steering pump to boost the power brakes (not vacuum). It had a leaking master cylinder ("normal seepage", but that's another story). I got it home after the dealer replaced the master cylinder and checked the power steering reservoir and zippo, nada, none, not even a drop in sight inside. I guess I should be thankful they at least put brake fluid in it. Thank heavens I just drove it about 3 miles.

I hope you are right. When we where going down the hwy my son said he smelled something burning. Then the high pitch sound started. At lower speeds the sound would come and go. We were going camping for Thanksgiving about 350 miles from home. I feel I have lost my confidence in this car. I hope I gain it back, I really feel this is the best suv on the road.

Just talked to the dealer, they said it was the drive shaft. I find that hard to believe, but they are a good dealer. They got the part shipped overnight and said I could pick it up Tuesday.

Just got a 2nd call from the dealer, after they replaced the drive shaft it still was making the same sounds. Guess what! They had to order a new rear end. Should have it back by Friday. They did offer me a car to take for the rest of the week.

Guess that's why they are car mechanics and not rocket scientists.

Just got my car back from the dealer. I looked at the old rear end and I swear that it is alot bigger than the one on my 05 Titan. I am not a engineer but it looks stronger than the one on my Titan. I still love my Armada.

Hmm.. I know the rear is different because of the rear suspension, but I thought the center section would be the same. I know our diff covers look completely different.

Does the Armada have the same Dana 44 rear end as the Titan, but slightly modified?

SCR38, I'm looking at you.

same ring gears different pinions, different housings. Equivalent to the Dana 44's except for the housing and CV joints. R230 Dana on one end and Dana 405 I think on the other. The exact models are in one of my other posts.
