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?

I've got it. I had the slip yoke greased once and that helped temporarily. Now it needs it again.

Do you guys have a one or two piece drive shaft?

It still amazes me how so many are having this problem when many others aren't!

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.

• REAR DRIVESHAFT SLIP/BUMP - BUILT ON OR BEFORE 12/1/2009

Publication Date: December 7, 2009
FORD:
2009-2010 F-150

ISSUE:

Some 2009-2010 F-150 vehicles equipped with a 2 piece driveshaft only and built on or before 12/1/2009 may exhibit a rear driveshaft slip/bump concern on light to moderate acceleration from a stop or when coming to stop with light braking.
ACTION:

Follow the Service Procedure steps to correct the condition.
SERVICE PROCEDURE




It is not necessary to remove the entire driveshaft from the vehicle for this repair.

1. Place orientation marks on the rear driveshaft flange and differential pinion flange.
2. Mark the center slip yoke barrel across the boot and the clamp crimp heads to the rear shaft spline stud shoulder. (Figure 1)
   
   
   Figure 1 - Article 09-25-5
3. Remove the clamps from the center slip yoke and discard.
4. Remove the rear axle to driveshaft flange fasteners and remove the rear portion of the driveshaft only.
5. Remove the boot
6. With a clean towel thoroughly clean old grease from the splines on the slip yoke and the stud shaft. Do not use solvent.
7. On 4X4 vehicles only, using hand tools, loosen the center bearing bolts and slide the center bearing fully rearward in the slotted holes. Torque fasteners to 35 lb-ft (48 N-m). Refer to WSM, Section 205-01 for detail.
8. Evenly coat the driveshaft splines with 0.53-0.71 ounces (15-20 grams) of Motorcraft® PTFE Lubricant.

10. Install the rear portion of the driveshaft into the center slip yoke.
11. Fasten driveshaft flange to the rear axle using the previous alignment marks for reference. Refer to WSM, Section 205-01 for detail.
12. Position the clamp heads in-line with the alignment mark on the slip yoke and stud spline shoulder to minimize any balance shift.

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.
