2005 Ford F-150 2dr Regular Cab XLT Rwd Styleside 6.5 ft. SB (4.2L 6cyl 5M)
When I first got this truck it pulled hard to the left during braking. it took 3 months for them to fix the problem. It has 3 vibrations, 1 in the motor they say it is normal per Ford. They replaced the driveline, they rebuilt the rear end replaced the rotors, the calipers, brakes, and changed something in the fuel economy system. It now gets 16 mpg, through all this I still have two vibrations and a wobble at 35 mph. I now have a different mechanic looking at it. He says it looks like a driveline problem and motor vibration, and something to do with the transmission, due to the 45 to 55 mph vibration.
Exterior and interior is great.
Fix the vibration from v6 motor, driveline, recheck the calipers.
