We put two new tires on the front of the vehicle in July 2006 on our 2004 Mercury Mountaineer awd. In Dec 2006 we took the vehicle into the dealer south hills Lincoln Mercury for a transmission problem and state and emission inspection. The dealer fixed problem with transmission, and did inspections. Then two weeks later,on new years eve, we broke down. Vehicle was towed to nearest Ford dealer in bedford, PA. The bedford dealer said due to the different "circumference" of the new tires on the front and the older tires in the rear it ruined the differential and transfer case on the highway. Our manual states nothing about this only says to put on the same style and type of tire which we did. They said the circumferences of the tires can not be more than 1/4" different. The factory rep says if we would have taken the car to the dealer for tires they would have told us this. They are blaming the tire dealer for not knowing this tolerance. The tire dealer says 1/4" tolerance is ridiculous. The cost of the repairs and rental car is over $5000. 00 south hills Lincoln Mercury in pittsburgh was going to honor the warranty secretly for me, because they sympathized with my problem and I think the service mgr there knows Ford has a bad engineering drivetrain. However bedford Ford notified the Ford factory rep and now south hills Mercury is backing out of honoring warranty. My complaints are: why doesn't the manual state anything about the tire circumferences? is this really the cause? 1/4" tolerance is way to small in the engineering of the drivetrain? - if one tire gets damaged after 10,000 miles you have to replace all four tires I guess? why was one dealer going to honor warranty and the other not? why didn't the dealer notice this problem when they inspected the car and worked on the transmission problem? part of the inspection process is to measure tread depth. If there was a big difference shouldn't that have been a red flag.

Purchased the 2003 Mercury, Mountaineer, awd vehicle new on 6/17/03. On 05/10/06 at 50515, the left front hub bearing had to be replaced. A visual exam indicated water damage with bearing seizure. On 11/24/08 at 88826, the same problem as the earlier hub replacement was diagnosed. At this time both the left and right front bearing hubs had to be replaced. The right front hub was practically frozen and showed signs of heat fatigue to the outer casing. Both hubs showed rust and pitting. I maintained possession of both hubs for future reference. There is no doubt in my mind that had the hub locked up on the highway while traveling at highway speeds, (70mph) a potential for a rollover accident existed. On 11/21/06, a rear differential noise was diagnosed. The rear differential was rebuilt. On 11/24/08 the noise was again heard coming from the rear. Apparently the noise from the front bearings damage shielded the rear diff. Noise. I notice only one other complaint for the particular model year, however the basic drive train design has not changed for Mercury or Ford explorer for some time and other model years may also have experienced this problem. There is no reason that a rear differential should not go 100000 plus miles without a problem and likewise there is no reason that the front hubs should not be able to roll up 100,000 miles without a problem. This is clearly a design flaw.

The contact owns a 2002 Mercury Mountaineer. While driving 35mph and losing control, the vehicle was in a ditch on a dirt road. The tie rod broke and two front tires had to be replaced and the truck is damaged. The contact has paid over $6000. 00 in repairs since purchasing the vehicle. The contact had to repair the front differential, lower ball joints, sealing for both shafts, four brake pads, bearings on all four tires, and the rear transfer case was flushed twice. Ford stated that the vehicle can be repaired. The contact is aware of the safety risk involved and request that the dealer purchase the vehicle from her. The failure mileage was 72,000 and the current mileage was 102,000.

2004 Mercury Mountaineer has hub bearing defects, transmission defects, drive train defects, rear axle and differential defects. There are thousands of complaints about these components of Mercury Mountaineer and Ford explorer yet NHTSA does nothing. Ford will not fix these problems and has been doing band aid fixes under warranty. They deny there is a problem yet there are thousands of complaints on the various web sites. It makes me believe NHTSA is in bed with the auto manufacturers and really don't care about the public. Wheels fall off cars cause hub bearings fail yet there is no recall. . Ford puts the wrong transmission fluid in cars, transmission fails. . . There is no recall. Rear axle seal fails and no recalls why!!!.

Defective front axle seals. Dt.
