Knock in rear with Dana 44

[entropy]

I took it to the dealership Thursday.

I had two noises for them to look at. This one and another noise I have. I gave detailed instructions on how to verify the noises, and of course, they didn't hear anything.

So I'm going down tomorrow to show them and demonstrate the noises.

The other dealership in town verified my other noise, but said that my pads and rotors were corroded and were making the popping noise. They wanted $660.

I hate dealerships.

660 for pads and rotors! dear God.

Yep, ridiculous. I done them myself for a little over $220. I had to. They noted it on a vehicle inspection of which I had to rectify.

And no, it didn't fix the problem. I and they knew it wouldn't. I haven't been back there. They get good reviews too.

20k mile update on the AD rear axle.
My passenger side axle seal wore out and was leaking. Ordered the parts myself and spent an afternoon at my cousins place using his lift to replace.
Rear diff oil looked good when we drained it. There has been zero issues with any knocking...and I'm running 35"s instead of 33"s now.
So, so far so good! But I'm still planning on going ARB rear locker when I finally re-gear though.

Now, I don't know what color Mopar dif fluid is, but this is dark, right? This has 10k miles on it.

Seems I saw some folks saying their dif fluid was dark that was having issues.

Diff fluid in a LSD is going to be dark by nature after any decent amount of use. It's the glitter and chunks that get you.

I didn't really see any metal shavings, and I assume the check plug is magnetic?

I put my phone in the storage compartment in the back. Is this the noise people are hearing?

Not for me, more a toc toc toc noise.

All of mine were nothing like that. It was a constant thunking sound while decelerating/coasting around 10-20 mph. I've got loud Magnaflow exhaust, so it was hard to pinpoint for the dealer, but once I removed the rear cargo cover it was obvious.

Mine does it when decelerating and coasting, especially down hill. The noises that I have on video from previously are all from inside the vehicle.

I got this one yesterday. You can hear it better the slower I get. If this isn't the sound people are hearing, this might not be my issue. But I did notice after going to bigger tires and wheels. I put the old tires and wheels back on and I did hear it a time or two, but was very faint and but not nearly as often

Sounds like it's gone bad from that video. It was louder for me on 33"s vs the stock setup.

thats fine. the LSD additive makes it dark too.

I went with 33s and noticed it immediately. The dealerships around here aren't open to anything on the internet.

Send a PM to @JeepCares about your issue. They helped me with number 2 replacement.

This is the noise i have. Dealer acknowledge but said nothing to investigate until noise gets worse. Ooened both diff and all is fine. Mime sounds louder but the toc toc toc when decelerating is the same.

You know what's causing it?
