In November 2002, I purchased a 2002 Ford F-150 extended cab, which was made in Canada 09/01. After the break-in period I noticed that at speeds of 80-85 mph the vehicle would whine, but I assumed that was normal because after 85 mph the whine went away. At about 89,000 miles and the end of the warranty, at 35-50 mph the vehicle would have loud roaring/whining noise from the rear end. Took vehicle to dealer for repairs on 10 January 2007, . the dealer replaced the pinion gear and assembly at a cost of $1501, and the dealer said it was fixed. I drove the vehicle less than 1,500 miles after the repair was made, the vehicle started doing the same thing again at speeds 40-50 mph, but with an added twist this time, the truck would whine even when I accelerate. I put the truck back in the shop for the same problem again on 01/23/2007. The truck has a 3.55 rear end.

At about 75K miles, a very faint whine was coming from the back end of the vehicle, mainly audible with acceleration and at speeds of about 35 mph. It slowly progressed, we took it to a local Ford dealership and was told that this is happening with many Ford 150's with this year, it was a defect in the parts (the material it was made with). We were told to continue to drive it until noise was too loud. At 92K miles, it was a pretty loud whine at all speeds except about 70 mph, and then progressed to a grinding noise. I just took it into the dealership, they said the rear differential, pinion and carriage gears were "torn up". they found a replacement and total cost is $1800. At this point Ford is not fixing part, since there is no extended warranty, but this is not a part that should be going out at 90K miles either, and with the dealership saying this is happening often and there was a defect in the part, Ford should be recalling this, or at the very least paying for the fix when it starts to go bad.

2002 Ford F150.

- Wilson, NC, USA

The contact owns a 2002 Ford F150. The rear end differential made a whining noise. They told him that it will not hurt the vehicle but it was not normal since the June 16,2005 contact was trying to get vehicle fixed. They replaced the rack and pinion twice, but problem recurred. The manufacturer told contact that they could not fix the vehicle. Technician at dealership said he owned the same vehicle and it was doing the same thing. The dealerships laughed when contact brought the vehicle to be fixed. At 40-45 mph contact could hear the noise, and if when pulling ta load the noise got worse. The dealership tried to fix this problem, but Ford kept sending wrong parts that were not correcting the problem. Contact has have an extended warranty on vehicle.

Truck is a F-150 with a 3.55 limited slip axle. There is a very noticeable whine coming from the rear differentail. Noise starts at 40 mph but is most noticeable at 60 mph. Noise is with slight acceleration, if I take my foot off the gas it stops. I have had the truck to the dealer three different times. They have replaced the bearings, drive shaft and gears but it hasn't helped. This is a widespread known problem but they don't seem to have a fix for the problem. I would never be able to sell this truck with this problem.

Loud high pitched whine in rear end at open highway speeds (3.31 gear ratio) detected day of purchase on March 25th 2002, reported to dealer of purchase (homer skelton Ford, olive branch, ms) next date. As of March 25th 2003, one year, two dealers, 29,000 miserable miles and some five repair attempts later I still have the same problem. There is defiently a problem with the 3.31 Ford rear end. I have recently driven another new 2003 Ford truck with 3.31 rear end, vehicle also had noise. Then drove another new pick up with the 3.55 rear end which was totally quiet. In the course of this year I have filed numerous complaints with dealers and directly with Ford. One week after purchase, when the first attempt to fix the truck failed, I attempted toget the dealer to take the truck back but they said that was not an option. This vehicle is suppose to ba a top of the line Ford pickup retailing for over $30,000 with a 36,000 mile bumper to bumper warranty. Ford either can't or won't fix it. They have just offered me a buy back on the truck which if accepted would cost me as follows the out of pocket expense at the time the truck was puchased. $1,875 cash down payment $6,162.10 equity of trade in $874.52 sales tax a total of $8,911.62. In addition to the cost of installation of personal equipment which totals about $400. This is not even considering payments on the truck for 12 months. Now Ford has offered to buy the truck back if I pay them over $5,000 additiional dollars for the mileage on the vehicle. This would make my total cost over $13,900 for owning a defective Ford pick up for 12 months. In essence there is no warranty. It should be Ford's responsibility to fix the defect in the vehicle. If they could not fix it they should have given me another truck long ago. It is their fault that it has taken a year to get to this point. I travel in my job and had no choice but to drive the miles on the truck. They certainly were not pleasant ones.
