Hi Pearl, I'm having a very unusual problem with my Ford F150 4.2 liter 2003. Whenever I am driving on roads that have wavy concrete patterns in the surface of the road it causes my truck to begin to shudder slowly and to vibrate the entire vehicle and sometimes the shudder and shake becomes so intense and forceful that I feel as if the truck will fall apart if I don't slow back down and try to reach a smoother surface road. This violent shaking only occurs over wavy concrete roads and it doesn't occur at all when driving over smooth surfaces.
JA: What year is your F150?
JA: Are you fixing your F150 yourself? What have you tried so far?
Customer: I have had both lower ball joints and control arms and tie rods replaced by A Ford dealership service center, including alignment. I have replaced both front brake
calipers and caliper brackets and brake pads n the last week as well
JA: How old are the rotors? How many miles are on the car?
Customer: I have 125,000 miles on the odometer. The rotors are original to the the truck as far as I know as I am the second owner
JA: Anything else you want the mechanic to know before I connect you?
Customer: I can't think of anything else to add at the moment
