Normal-- replace rotors and pad
Vibrating between 45-55 mph took it to have the driveshaft checked out and was OK. Now goign to change trans fluid to see if it fixes the problem.
Truck is pretty quick, Handle good until about 80mph then the steering gets a lil wobbly. Haven't had any problems so far just rountine repair just don't know why it's vibrating a a certain point.
I have a 93 jeep Cherokee, it also has a vibration at around 45-50. It also starts to get squirlly at around 70. The larger suspension doesn't work very well at high speed, air under the vehicle. For the vibration it could possibly be the drive shaft or transmission, but my Cherokee stopped vibrating after I had all the wheels balanced and rotated. Good luck with your Explorer!
Look dude, if you want to post a comment about your cherokee, then take a hike over to the CHEROKEE section, and besides, what exactly does your cherokee have to do with a ford? jeep...ford...jeep...ford.
