1) driving down a paved road going about 35 mph. 2) heard a loud bang and then a metal grinding sound. The driveshaft forced its way and busted through the center carrier bearing. It only needs to happen once and it cannot be fixed. The center carrier brearing is snapped. This part holds the driveshaft. Without the bearing, the drive shaft will hang down and grind against the pavement and throw it out of balance and damage it. Eventually the driveshaft will break in two. Then the truck will lose power to the wheels which can cause an accident. 3) the driveshaft from Ford is nonserviceable. If any 1 part fails you are buying a complete new driveshaft for upwards of $1,200. None of the parts can be replaced. The driveshaft for my truck costs $1200 from Ford. The center carrier bearing could not be replaced because the bearing is installed before tube was friction welded (bad) in place. The bearing cannot be changed without cutting driveshaft apart, destroying the driveshaft. This part is only $35 but you have to buy a complete new driveshaft. I found a company that specializes in driveshafts and makes serviceable driveshafts for Ford trucks. I have heard others have this problem so this is a common driveshaft defect with 04-05 Ford F-150 trucks. I bought the new driveshaft from www.driveshaftspecialist.com F or $725 + installation. This is less than what Ford charges but is not something I feel should have to be replaced on a newer truck with this mileage and that is driven very lightly unless there is a defect in design like there is with Ford F-150 drive shafts. This is something thiat is supposed to last the lifetime of the truck.

Ever since delivery of vehicle (2005 Ford F150 lariat 4WD), vehicle "shutters" or "jerks" on acceleration from a complete stop. Initially there was also some "popping" on turning and acceleration, which was fixed by the dealership. The shuttering has been fixed, but after 3 repair attemps, the truck continues to jump/jerk on acceleration from a complete stop. The dealership states this is normal, but the driveline only jerks when in 2wd mode - it does not jerk in 4WD. To get the shuttering to stop, Ford installed a shim kit to align the driveline, which they state is a problem they finally found.

There is a loud clanking noise in the rear end when taking off and when shifting gears. It jumps so bad sometimes you have to stop the vehicle and let it cool off before resuming ride. It's being having this problem for the past 2000 miles. Have taken to the manufactor and the dealer. It's been at the dealer 3 times for this problem alone. No parts have been replaced. The dealer told consumer that if there was no recall they couldn't fix it because all the trucks 2005 F150 regular cabs have the same problem.
