2011 F150 Shudder
Just about three weeks ago I bought a brand new 2011 F150 Lariat 4x4 Super Crew with the 6.5' bed. For the most part I love the truck. However, it has a REALLY obnoxious shudder going between 1st and 2nd gear. The dealership told me it was driveshaft shudder due to the two piece driveshaft. They shimmed the driveshaft and it's no better. To me it feels like the truck is almost "fighting itself" in first gear, kind of like its not free to rotate the driveshaft. I don't even have the license plates yet and have had it in for this twice now. It's really frustrating.
Is this normal for these trucks? Can it be fixed? If not, what kind of damage can expect from the shudder as I continue to drive the truck?
