FWIW, I've tried lubricating those plates twice now. Once with silicone spray, and once with break-free. No effect on the clicking noise.

 

Yeah - this. Anyone tried it? Or anyone stuck some gasket goo or a homemade gasket in there? If no one has - I'll take a shot this weekend.


I'm just going by the picture posted in this thread (first time I've "seen" the actual cause - and I've followed a few threads on this issue) and it looks like if A & B in the pic are whats making the noise, there's no reason why we can't shove something in between them - from what I can see - that might quiet that pop/clank noise down.


Anyone have any thoughts?

 

Gentlmen, Please dont put anything between the two plates. The bolts are doing all the driving from the driveshaft to the pinion plate. Any movement will cause a failure. Bad things will happen.
If you think the noise is coming from there, take the bolts out, check the two plates for signs of movement or chaffing, gauling etc. Check the bolts for signs of movment or side shearing. Check the ujoint for free playin all directions.
On reassembly, clean the rust from the mating surfaces with sandpaper or scotchbrite pad. If the bolts look ok, clean the bolts and the threaded holes with some brake clean. Let dry and put some loctite on the bolts and torque bolts to spec.

 

This issue just started on my 2013 with 32K last week. I have an appointment for Tuesday with the dealer.

 

Be sure to let us know how things go on Tuesday, dtaylorfd. I'll be happy to do what I can to help if you need assistance after you get a diagnosis.

I wish the dealers were even interested in getting a "diagnosis." Mine told me it was probably the brake pads shifting (it's obviously not, and I explained to him why that would be impossible). He went on to tell me that he could chase that noise for a month and still not find it, and that noise on a truck are what give it character. Pfft.

 

Same here as everyone else. My dealer just said "it's normal" - service writer said his 2014 does it as well and he just accepted it as part of the normal operation of the truck. Funny stuff.

 

Your parking brake pads retaining pin can make that same noise too.
