I need help identifying a noise.
Just got back from the garage and the news is not good. First off let me say that it really pisses me off when a mechanic dogs my vehicle for twenty minutes on a "test drive". At 3.59 miles per dollar no less.
So, according to Evil Knievel, my whole rear end needs to be rebuilt. He said that the axle gears are wore out, the pinion and bearing are wore out and the locker is wore out. He surmised that the rear end had been run dry at some point and that "they just put any old oil in it". Bear in mind, he never even checked the oil, I did previously and I cannot verify the weight of the oil but it is sure smells like rear end oil. He also said that the transfer case was shot. I don't know how he came to that conclusion, my mind was stuck on "the noise you hear when you really get on it and turn sharply to the right"....
Sorry if I sound miffed, just not been a great day.
Long story short, they wanted to do an 80 dollar dif service knowing that it was going to be a waste of $ for me. I told them thanks but no and made an appointment instead with the guy that re geared my 62 Ford F250 so it is going there on Monday morning and I will get his opinion and let him build it.
I will update with the end result.

Here's the latest.
I took the Durango to a guy that only works on rear ends. He test drove it and said it sounds like either a wheel bearing went bad and wore out the axle bearing or vice versa. That caused the pinion gear to tilt slightly which is the noise I am hearing. He said it would probably need a new carrier bearing and hopefully the pinion is salvageable. This was his opinion on a 1 mile test drive. It goes in Tuesday so that he can tear into it and get it all fixed up! YAY. He also said that if the pinion is still useable and that it may still make some noise, not much, but that it would be fine. Anyway, we shall see.
I will update again when I have more info. I appreciate all of the input from you guys.

BTW, for anyone interested, I found a really good page that describes the majority of noises that may be going on in a rear end that might be hard to diagnose. I wish I had found it sooner! Just Google Diagnosing Drivetrain Noise by Randy Lyman.

Now that sounds more plausible then the last *** hat!
The only thing I didn't like was the axle bearing and wheel bearing part because there is only one bearing on the outside of the rear axle, and that bearing is called a wheel bearing. But other then that, he again sounds like he knows rear differentials. Your better off having a guy that only does differential work because those are the ones you want. Regular mechanics either wont touch em or have screwed them up because they are really hard to work on. If you don't get them right the first time it is a HUGE PITA to fix.
Anyway, with that said he should replace all the bearings including the pinion, carrier, and wheel bearings as a minimum. Also he should replace the yoke seal. All of this comes in a master kit and that is what he should have bought because you get a great deal when you buy them in the kit. The kit will also include shims and a crush sleeve. The one I bought for my old 1998 Durango was about $120 bucks or so from www.sixstates.com
So most people mark up parts 100% plus they charge labor, so plan on spending $200 for that kit, fluid,,,,ect, and install.
You mean this.....LOL http://www.4x4now.com/gt0699.htm

I think he was talking about the bearing on the differential end of the axle, that was how I understood it, but I really don't know. He did say he would use a master kit on it, that it would be cheaper. He also said, which I just remembered, that the posi-trac (spelling) was messed up, probably why it has acted up on the gravel on my rather steep driveway. Anyway, he said he would fix me up, I just hope it doesn't cost a small fortune.
"You mean this.....LOL http://www.4x4now.com/gt0699.htm" yeah, why, no good?

No, I've used that same informative link is all......
Yes what he described is in fact the wheel bearing. It goes on the end of the axle that is inside the axle housing. Now you do not have a Posi-Traction rear differential, there are 4 styles used.
Chrysler Corporate 9.25
Chrysler Corporate 9.25 Trac-Lok (Limited Slip version)
Chrysler Corporate 8.25
Chrysler Corporate 8.25 Trac-Lok (Limited Slip version)
Anyway, I think he was talking about that you might have a Trac-Lok LS rear end and if you do then he is most likely talking about installing new clutch packs, which at wholesale cost is about $100 bucks on top of the master kit. All in all, it just depends on what you got in there.

oh, okay. He said that, whatever it is, would prevent me from being able to pull out in the snow. I have a 9.25 rear end, he sounded somewhat surprised when he saw that, said it didn't usually go bad. Anyway, I will know more on Wednesday, he should be into it by then. I am so hoping this doesn't go much over a grand...hard times ahead.

That sound...
I think I'm having the same problem. That sound you talked about -- is it like a whirring/straining sound? I've noticed my '02 4.7 has just started doing this. It happens when I accelerate or declerate, once i'm over like 10 mph. It almost sounds like amplified road noise. I don't know how else to explain it. Almost like the the brakes are on while I'm accelerating. Is that similar to what you are experiencing?
