Right on Crystal.
The F150 community and/or Ford Service representation on this forum should be keeping a mileage or affected user log for this wide spread problem.
My example is as pathetic as everybody else. Meaning brand stinking new 50k dollar 2013 truck, clicking problem started at approx 6k miles and TSB was first performed at 9k miles. We'll see how many miles this buys me before needing the TSB service again.

I had this exact issue with the snapping and popping while shifting and driving in reverse. After they "tightened" the pinion nut this happened - https://www.f150forum.com/f38/scary-...veable-206415/
They replaced the rear diff with a new one and the snapping started again about 3 months ago. I was told they used "bearing mount" to fill the voids between the pinion and spline instead of manufacturing the proper tolerances. I sold the truck the following week. To me this is bull**** and I will not stand for it so they have lost my business for life.

^ This is why if I end up with a 14 F150 I'll probably check the pinion pre-load and make sure it's within spec. I don't have much faith in dealers working on axles. Not much axle work gets done anymore with FWD's and not many techs are truly experienced in building axles. If my new '14 develops the snap/click and they want to rebuild the diff, that's fine, but I need to witness it and see the gear pattern, lash and pre-load. and with the TSB out there with everyone getting the axle rebuilt for the click/snap I think the techs are wanting to over tighten the pinion pre-load to avoid come-backs. But then a few weeks later your rear end locks up, drive shaft falls out and post on the forum. I rather have a click/snap and personally know that my axle is within spec vs some idiot at the dealer rebuilding my axle that has never done one before and only does lube jobs. I built all my own axles in my rock crawler. That's the kind of job you have to personally know gets done right.

And if these axles are locking up think of the problems this poses on sudden stoppages... On the tranny, transfer case, mounts, bushings....heck even the tires would prob have flat spots...does the dealer even think of this stuff that could show up after the axle is fixed, I bet not

Fixed
2013 EB 4x4 3.73 gears Tow Package E-Locker - 12k miles or so, developed "The Clunk" and I lost about 2 MPG.
Dealer replaced the ring and pinion, bearings, slinger etc....all the "pumpkin guts" as I saw it called, except for the e-locker parts. Problem solved including MPG. During the weeks before this fix I had to really feather the throttle to get 16mpg..after the fix.... 18mpg when I feather the throttle.
For me, the MPG was s sign of problems. The first year I consistantly got 17.5 mpg combined town/city driving conservative. The past 3-4 months I struggled to get up to 16.0MPG, more often than not it was low 15's. Whatever was going on in the rear end was affecting my gas mileage. Driving around after the fix, no problem getting 18MPG (probably will go down as I put more city miles on).
So, along with "The Clunk" sound, there was some extra friction/binding going on that caused gas milage to suffer. I've seen several threads about gas milage going down to 12's and 13's ... maybe the rear end has something to do with it.
Happy with the fix...hope "The Clunk" stays fixed.

I noticed a click-snap after 6,000 k breakin period with a new 2013 f150 crew 2wd short box.I operate a small home based transmission repair shop.37 years in the driveline business so I like to think I have some experience.After a couple of months of hearing that frikin click snap noise I put the truck on the lift and removed the rear tires,calipers and rotors.Then removed the 4 driveshaft to diff flange bolts.Note:This was done just to see if the pinion preload was way too loose.Tried to turn the diff flange with one hand and it wouldn't even budge [the pinion bearing preload was maybe 3 times over the specs......]It took 2 hands just to break it free.I quickly got a bit pissed-off with whoever that did such a thing knowing that crush sleeve and new pinion bearings, seal etc would have to replaced .So a couple of other glitches started to show ie: right front abs sensor fault,low battery warning etc. So I went down to the Ford dealer and had a tech go for a road-test to deal with the trouble codes.When we got back to the lot I mentioned what I found with the overtighted pinion nut.Well.....he got a little pissed-off and said to me ....This truck is under ford warranty and you have no business touching anything because Ford has the right to refuse a warranty claim.Well you may know what happened next..My bloodpressure spiked and told him what I thought of his bull-crap reply.The tech then said he has 20 years as a Ford driveline tech ....... I ordered pinion bearings, crush-sleeve ,slinger nut etc from my own supplier and will just do the job right here in my own shop....screw FORD
Something in the rear end was either binding or causing a lot of friction.

Does anybody know if the rear axle has a temp sensor and what the Ford PID is to call the data values? I have an OBD-II monitoring tool with extended Ford PIDs.
