2003 XLT 24K miles almost out of warranty first of August.
Calcification on rear axle noise?
I think my explorer in getting the famous rear end whine. At speeds
between 40 and 65 there is a loud whining sound BUT when I take my foot off
of the gas the whine sound quits. Is this what everyone has been talking
about or something else?
My 2003 Lincoln Aviator has a noise coming from the front drive assembly. It sounds like the old knobby snow tires sounded on dry pavement but not as loud.
Hate to burst ya'll bubble but I just got my 2003 lincoln aviator back after I had a front end accident took it in to have the oil changed and check for a transmission service also wanted them to check for a front end noise. Well go figure apparently its in the front differnential in something called the "vista clutch" anway it requires a new transfer case to be purchased. Apparently it runs about $2000 with labor included. Go figure the insurance company wont pay for it after already dumping $8000 in damages already to fix and stated they would not total my truck with 83000 miles on it. Well all I can say is i was told they only go out if they are burnt out from locking the wheels up and skidding and just 1 in a 1000 goes out so I guess we are just he lucky ones. Good luck hope this helps a little also make sure ther is nothing wrong with the gears cause it could create an even bigger problem.. Peace out!

Well, I can think of a couple of things. Number 1, are you sure the noise isn't comming from your rear diff. The independent rear end isn't as strong as the solid 8.8 axles of the older mountaineers. The toe links go out, and it causes the axles seals and rear bearings to go out. However, in this case I would look at the axle seals going into your rear diff. carrier. If it looks like your leaking, you could be blowing out the limited slip diff in the rear end. That would make a whining noise, and a lack of power because of the diff spinning instead of the tires. Now as for the transmission, that could be bad news. Ford does have a TSB for one of the internal parts wearing a groove in the casing. If I remember correctly it is one of the shift solinoids. That could be another cause the truck itself not going into gear. On the other hand some of the older Explorers had problems with the valve body gasket and that can do the same thing. So you may want to just change the valve body gasket and see if that fixes the problem before you have your whole trans remained. I know I threw a lot at you, especially with that added stuff about the rear end issues, but that is all items you might want to check.
While there aren't any open recalls I'm aware of for that concern, it may very well fall under the powertrain warranty (5 years, 60,000 miles). The most common rear end noise concern we get is a chattering/noise from the rear end in turns caused by the breakdown of additives in the rear axle fluid causing the limited slip clutches to chatter. The cheapest, easiest fix for that concern is an $8 bottle of "friction modifier", available at the dealerships parts department, that you can add to the rear axle. It will work its way into the friction material, usually quieting the noise after 500 miles or so.
Unfortunately, this is a somewhat common problem. Ford has issued several Technical Service Bulletins related to rear end noise. Without an extended warranty, this is something you will have to pay for.

REAR AXLE NOISE REPAIR
1997-2005 Expedition, F-150
Some vehicles may exhibit an axle whine or hum during acceleration, deceleration and/or cruise.
An axle repair kit has been developed which incorporates most parts required for a comprehensive axle repair. The kit should be used instead of installing a complete axle assembly to repair an axle whine/hum. Replace Ring and Pinion with Axle Kit and Components.

Summary: WHINE NOISE FROM REAR AXLE. *TT I just went through the same problem with my SS. It had 3000 miles on it and it was whinning while turning either left or right. I took it to the dealer and they replaced the entire rear axle. I am not the first person that I know to have this problem. I was told that there was a problem with some of the rear ends and I have had no further problems since having mine replaced. Thank you for using Fixya and good luck
if its a grinding noise while driving it could be choppy tires carrier bearings or axle bearings.
if its a whine while accelerating or decelerating than it is pinion angle.
if you can safly get both rear tires off of the ground than start it and put it in gear, try to locate the exact location "center chunk or out far in axle tubes" make sure vehicle is secure and safe befor climbing underneath.
i know for a fact that the bearing comes with the hub., and if the old bearing is badly damage you may need to heat it to remove it from the axel...so this may be a rather big job if your not equipt
with torch or other ...
