at 26250 miles my f150 xlt supercrew 2wd needed the ring and pinion and complete drivshaft replaced.I took the truck in for whine in differential previously before warranty expired.Ford dealer in Riverside CA said mechanic could not hear whine at freeway speed.Told CJ that whine appears at 75 to 78 mph only. CJ assured me that complaint was in their system if problem gets worse.Four months after warranty expired truck had annoying clunk upon takeoffTook to same dealership and talked to CJ again.He said Ford would not honor fixing and complaint was not logged in their system.After numerous calls to Ford corporate they agreed to assist me with problem since i was a loyal Ford customer with 2 other Fords.I had to pay $850. for more poor quality.If you suspect something is wrong with your Ford and your near end of warranty do not accept their promises...leave it their or ride with the technician to get fixed the fist time. 21k miles front rotors worn. 26250 miles differential rebuilt with new ring and pinion.also entire driveshaft replaced. 31333 miles rear door window motor and cables fall apart.This is a family transportation truck only. No commercial use or offroad...NEVER another Ford....

Noticed that the truck stuttered and shook when starting from a complete stop. Thought it might be electrical and one shop actually thought is was the plugs. After several shops went through troubleshooting they found that the rear had to be rebuilt and possibly replaced if they found it ground up too badly (working on it now). Last truck I had was a 2002 F250 and the rear axle wheel bearings went out (completely shot) at 67,000 miles.. This is the last Ford I will own. Ford needs to step up to the plate since its obvious others have had the same problem.

After replacing all 8 spark plugs (3 which broke off in the head and earlier then required) , both cats (1200), and all differential seals front and back, I thought I was good. Then every time I turned left or right I would get a bad vibration, almost like I was hitting several holes. Turned out the rear dif is chewed to hell. I can't believe that ford would put out a product that fails on so many levels. Screw ford to the floor if you can.

After reading this forum, it sounds like I need to have the differential rebuilt @ 50K. For the past four months I have ignored the shuttering in the drive train when turning and accelerating. The rear end feels like it�s spinning on gravel when starting from a stop. Ford knows there is a problem and they won�t have a recall. Sounds like another future class action lawsuit.

I had just bought this vehicle used when the differential starting grinding and shaking while turning and accelerating. The local Ford dealership estimated $1200-$1400. I took it to a local powertrain service and got it repaired for $600. Apparently this is a chronic problem with this model and I would highly recommend purchasing a Chevy.

Rear differential failed. Heard grinding sound and felt grinding sound under rear passenger seats. Took to Ford dealer where truck was purchased and they said one rear rack and pinion bearing went bad and they rebuilt it. Ford offered up 50% of the cost because I had to complain about it multiple times. Trucks are usually getting to the "broken in" stages around 60k miles seems to me that Fords are broken in and beyond at end of standard warranty 36K miles.

OK, this is f150 # 2. The rear diff. started shaking when starting from a stop. It felt like the tires were spinning on loose gravel. This is the same problem we had with f150 # 1! Dealer fixed it under warranty.

For the past five months I have ignored the shuttering in the drive train when turning and accelerating. I recently talked with another person who owns a 2004 F-150 and his differential failed last summer at 38,000 miles. I have not had the truck fixed, but now understand this is a widespread issue with Ford F-150s from the 2004 model year. I hope Ford addresses this problem, else I hope for a class action law suit to help cover the costs of repair. My truck is mostly (99.9%) a paved road vehicle and has not been abused. This is not ford tuff. I expect better from a KIA. If not properly addressed I will move to Toyota. I have owned three F-150s (2000, 2001 and 2004). Until now I was very happy.

I thought this was a tranny problem. Symptom was a hard shift at low speeds. If your Truck is doing this, have the rear diff checked!!!

Had to have the differential replaced right after the truck came off warranty. There was even a TSB issued on 11/28/05 in reference to the faulty differential. Of course, Ford only offered to pay for the parts, so it still ended up costing me $850. If Ford knows there is a problem why don't they recall the damn thing. Of course, my letter for full reimbursement was rejected. Hello Toyota, anyone wanna buy a Ford?

Ford is a great Toyota spokesperson. My 1989 F150 differential failed at 100K miles. My 1995 F150 differential failed at 100K and again at 200K miles. Now my 2004 F150 differential has failed at 100K miles. Maybe I'm a slow learner.

F-150 Lariat 5.4L V8
Bought my 04 F150 4X4 in Feb @ 68K miles. In May with approximately 70K, started feeling vibrations when turning from a stopped position. The local mech said that the rear clutches were locked up? He also said that the truck would probably run for another 100K miles, but that it would annoying. Either way, it was going to require a rear end rebuild. How would the process start for Ford to do a recall, or extend a fix of this problem?? Obviously it's a design flaw of the rear differential.
