Drive line Clunk
My 2010 Ford has been in the shop three times in less than 5000 miles to have my driveline clunk addressed. I am being told this is occuring in all of the new trucks which I don't believe. The issue has been addressed by removing the drive line and lubing slip yoke with teflon grease. I have been told that this is normal and my solution will be to have it lubed when my oil is changed. Is anyone else having this problem in their new ford f150?

Here's the TSB that addresses this problem, the reason some experience this and others don't, is that it applies to trucks built before 1 Dec 09. Although my truck was built in Oct 09, and I haven't experienced the bump.

I have an 08 fx4 thats been in the shop about 5 times in the last year and half. Had its greased and replaced, still having issues with it. The bump is gone, but the noise is still there. Its annoying, but they said its normal. Thats there way of saying we dont know what else to do.
