I recently purchased a 2001 F150 Supercrew. It is 4x4, 5.4L, with auto trans. w/overdrive. It also had new Michelins installed prior to the purchase. I have noticed that when braking , the truck feels like its trying to hop or vibrate. The stering wheel does not vibrate like a warped rotor. It does not do this every time the brakes are applied. Also, just before you come to a complete stop, say at a light, You can sometimes feel the same pulsing or vibration but at a much lesser degree. Im wondering if it could be the torque converter in the transmission. I am taking the truck to the shop Thurs.for recall service and plan to have the transmission flushed then with a new filter installed. Any other suggestions of what to look for? Thanks.

so what did they say the problem is?

Sounds like the new Michelins could be the problem. Are they a much different size than what came on it? Were they properly balanced? Did they tighten the lugs up properly? Are they aired up to MAX?
