I bought a 2003 Ford Explorer in June of 07 with no problems in Sept of 07 I started to experience a load noise coming from the rear of the vehicle sounding like a tire was flat or something was rubbing. I took it into the shop and they told me that the rear diff was out on this and it was going to cost several thousand dollars to fix. I contacted Ford they acknowledge the problem but refused to fix it and said that it was not under warranty so they weren't going to do anything about it. I now sit hear with something that I owe money on and can not afford to fix. I have a wife and a son and this is our only mode of transportation. I am very upset that Ford does not stand behind their products like they should. There are numerous complaints on the internet about the same problem but with no solution.

I was driving my 2003 Ford explore and I started to here and noise from the rear end when I took off from a dead stop. I didn't worry about it right any, then it kept getting worse, so I took it in to the Ford dealership where I bought it and they said the clutch was bad in the differential and it would be between 500 to 700 to fix. This Explorer only has 49,000 miles on it. My wife drives this car and I know it has never been beat on. I still do not have my truck back yet it has been in the shop for about 4 days now. I am about up to 1200 dollars in repairs. I have read several complaints about this same thing on the internet. I juast can't understand why they don't have a recall.

I purchased a 2003 Ford Explorer XLT. I quickly noticed a noise from the rear of the vehicle when speeds of 55-60 mph were achieved. After bringing the vehicle to the auto repair shop I was told that the rear differential needed to be replaced and that it was not only dangerous to drive but extremely expensive. After some research I have discovered that this is a common issue with the Ford Explorer. Should this type of repair that could result in human injury, be addressed by Ford. I am hopeful that your answer will be yes!

- the contact owns a 2003 Ford Explorer XLT. The contact stated that the vehicle was making noises, wining, and grinding. The contact stated that the differential system failed and needed to be replaced. Also, the following components needed to be replaced: Clutches, ring, pinion, carrier bearing, pinion bearing, and pinion seal. The contact had to update the axle seals. At the time of the original failure the vehicle had an odometer reading of 37,000 miles and the warranty had just lapsed. The contact did not believe that the weather was a factor, and the sounds were always when she was in the process of accelerating. The contact stated that it started very slowly and became an every day occurrence.

My 2003 Ford Explorer 4X4 has developed a severe binding, shudder sensation in the rear axel during low speed turning maneuvers. It also has a whining sound at highway speeds, typically 55 - 70 mph). This vehicle has only 34,000 miles on it and the dealer wants to rebuild the rear axle/differential - at my expense since the 3 year warranty time limit is up. If let go, the Ford dealer indicates the rear axle could 'blow up' (their words), resulting in a complete loss of drive to the rear wheel. I have discovered at least six (6) technical service bulletins issued by Ford on this problem! this is obviously a bad design and latent defect which can effect the safe operation of the vehicle.

2003 Ford Explorer eddie bauer. 50 to 60 mph rear axle whine started at 6000 miles, at 12,000 miles dealer inspected and said the rear axle assy was unsafe to drive and replaced the assy. Whine returned and dealer replaced the assy again at 24,000 miles. Whine has returned and I am considering going to independent shop to repair since beyond 36,000 mile warranty. Can't understand why Ford can't fix this widespread problem.

Roaring sound coming from the back end of the truck.

- Glasgow, KY, USA

Purchased new 2003 Ford Explorer. At around 9000 miles had rear end replaced due to infamous loud whining noise. Problem improved...but was not completely fixed. After complaining that there was still some noise, sale Ford in kingston, nc said it was "uneven tire wear." Replaced 2 tires. When taken back and told there was still a problem, we were told that they had "done all they could do except offer us a good deal on a trade." (like we will ever buy from them again). At 59,000 miles, we are now having rear end "chatter" when starting or stopping. Ford is crap and so is their customer service.

Whining noise coming from rear became louder 41,000 mile on odo dealer advised rear wheel bearings seals and strut inserts, we had the repairs made $1000 one year later we noticed more noise and chatter when turning, dealer advised rear differential needs rebuild, and new clutch packs. We are having the repairs made at this time. These are expensive problems Ford should be held responsible.

2nd rear differential needing replacement (replaced rear end and both axle bearings). This replacement at 73,971 miles. Previous rear differential replacement about 12K miles earlier. Neither replacement covered under warranty, however 2 failures and the second at only 12,000 miles.

- Decatur, GA, USA

After a shudder was felt in the steering at 14,580 mi., it was discovered that the problem was in the rear-end. Ford recommended a rear-end additive. (which was performed). At 37,000 mi. The shudder returned and a new clutch pack was installed in the rear-end. After receiving car from dealer, a whine started to occur between 50 to 70 mph. Took back to dealer and was told this was normal. I called Ford motor and they recommend that a "ring and pinion repair kit" be installed to prevent failure. Dealer does not think this should be installed and that vehicle is O.K. to drive even though the tech can hear the noise.
