'09 1500 pinion snapped
#21
FWIW...that is an opinion, not a fact. I looked into this, and had my original pinion nut Loctited and peened. That was 8,000 km ago. No issues, no leaks, no noises...all good. I'll report back in another 100,000 km....

What I'm having a hard time understanding is that you NEVER hear of this issue from the 3rd Gen owners, even though SUPPOSEDLY the axle/drivshaft combo through the '09s (and some early '10s) are the SAME AAM (Chrysler Corporate) 9.25 axles.
Too many reports of this issue abound to ignore the problem - so what did they do that's different for the 4th Gens??? I'd sure like to know...

FWIW - loctiting a pinion nut is also wrong. You can't set the torque correctly when you have smeared any kind of gunk on the threads, the torque value is a dry value.

I heard that! I learned the hard way about welding the spiders and then getting a tire wedged between a rock and a hard place once many years ago, LOL...

No pun intended but I think some of these parts are made in China no to mention are'nt some of our truck parts assemble in Mexico? I'm pretty sure I remember something about the defected tie rod ends were made in China anyway. Could just be better material on the 3'rd gens...just saying.
Could be - but made in china doesn't = poor quality any more than made in USA means good quality.

Typically pinion nuts are either the staked type or stover type and are designed for single use. Diff kits always include a new pinion nut so that they are not reused when replacing bearings - then again, some folks will reuse crush sleeves

Interesting. The NHTSA and Transport Canada recalls for pinion nuts coming loose states the nuts were installed "without the proper amount of adhesive". Guess the factory doesn't know the torque value is a dry value. Driveline shop that checked my pinion nut said "nothing leaves our shop without Loctite"
Well, I could post up the page from the FSM that shows the proper way to do it, but I suspect that wouldn't matter since you have "heard" so much. Good luck to you.

My comments have nothing to do with hearsay or what I've "heard". Your post stated that you shouldn't use Loctite with pinion nuts. The recent recall for pinion nuts coming loose cited an incorrect amount of adhesive was used. So, there is a contradiction based on published information not hearsay. Anyway, I'm content to agree to disagree. Good luck to you as well.

That said, I think I remember seeing that the reason for the tie rod end and rear end failures was because there were some bad batches of parts that were made in China. Not to mention the drain plugs were drilled in the wrong location on some. I'm well aware that some of these parts on our trucks could have both good and bad parts from both countries but I still like "Made in the USA".
