About 2 months ago my LDS started moaning on turns so changed to oil to amsoil 2000 its still moans took to dealers yesterday saying i didnt put the additived I said the oil has the additives he no it doesnt thats the problem I said no its not its was doing before I changed the oil thats why I changed it in so there r going put new gear oil and additive. I,ll be laughing when he calls and tells me there is a problem I cant stand dealers they talk to u like u r a dumb I been a mechanic for over 20 yrs and its not to listen to this people

Amsoil gear lubes do not require the use of an additive. But for some reason not all diff's respond the same. I still had noise, so I went with the addition of Amsoil Slip-Lock which Steve recommended in a prior post which eliminated the noise.

@26k on my 2k dakota quadcab, my independent mechanic did the scheduled differential fluid change ... and out comes a piece of one of the clutch clips and metal filings. My mechanic suggested I talk to Dodge. Dodge tried to sell me an extended warranty. I ended up with a transmission shop my mechanic recommended. He said I caught it early enough to save the ring gear and pinion, but had to replace the balance of the lsd (9.5", stop-sign cover). Cost 885 for the part and 345 for labor. I'm going to talk to a dodge cust supp guy - can't hurt to ask and clearly Dodge has a lsd problem here.
Any comments? Was the price reasonable? Is Dodge likely to do the right thing? Thanks.

Thanks Dak1979,
True: Per one of my prior posts --- AMSOIL Synthetic Gear Lubes DO NOT require the use of an additive. However, not all differentials respond the same and if chatter is noticed, the addition of AMSOIL Slip-Lock will eliminate it. For chattering differentials not running AMSOIL Gear Lube, this product is an excellent solution to the problem.
Additives? -- AMSOIL Slip-Lock Differential Additive
Effectively Eliminates Gear Housing Chatter
When making a turn, the outer wheels of a vehicle must travel faster than the inner wheels. It is up to the differential to act as a balance arm, establishing constant equilibrium of torques and forces between the left-hand and right-hand driven wheels. In standard (or open) differentials, power is directed to the wheel offering the least resistance. This works well when making a turn, but in a situation where one wheel is lifted off the ground, it causes the suspended wheel to turn while the other remains motionless.
Limited-slip (or positraction) and locking differentials are traction-increasing devices. Locking differentials transfer all available torque to both wheels. The teeth of the spider assembly engage with those on the locker clutch, causing both axle shafts to operate as one. Locking differentials don't allow one drive wheel to spin while the other remains stationary. Instead, they keep both wheels in drive mode, but unlock to permit different wheel speeds when turning. The engaging and disengaging of the teeth on automatic locking differentials often causes a banging and clunking sound. Manual locking differentials usually use an electric motor or vacuum diaphragm to engage the locker, reducing this noise.
Limited-slip differentials allow different wheel speeds when turning, but when one wheel loses traction, greater torque is transferred to the wheel offering more resistance. Limited-slip differentials make use of friction between clutch plates, as opposed to the meshing teeth employed by locking differentials. Transferring less torque per side, limited-slip differentials are generally smoother and quieter than locking differentials, but still sometimes "chatter" when transferring torque to the wheel with traction.
In some differential applications, a friction modifier additive is necessary to reduce chatter. AMSOIL Slip-Lock Differential Additive is formulated with advanced friction modifiers and is designed to eliminate gear-housing chatter in cars, trucks and SUVs equipped with limited-slip, positraction and locking differentials. It also reduces the banging and clunking associated with automatic locking differentials.
AMSOIL Slip-Lock Differential Additive is formulated for use with both synthetic and petroleum gear lubricants and safely replaces manufacturer recommended friction modifiers. Its convenient flip-top dispenser provides quick and easy application to the gear housing. One four-ounce bottle of Slip-Lock treats differential capacities of two to four quarts. It is not for use in automatic transmissions or other applications requiring ATF.
Repeat: AMSOIL Synthetic Gear Lubes DO NOT require the use of this additive. However, not all differentials respond the same and if chatter is noticed, the addition of AMSOIL Slip-Lock will eliminate it. For chattering differentials not running AMSOIL Gear Lube, this product is an excellent solution to the problem.
__________________________________________________
FYI - Gear Lube Information:
High quality gear oils must lubricate, cool and protect geared systems. They must also carry damaging wear debris away from contact zones and muffle the sound of gear operation. Commonly used in differential gears and standard transmission applications in commercial and passenger vehicles, as well as a variety of industrial machinery, gear oils must offer extreme temperature and pressure protection in order to prevent wear, pitting, spalling, scoring, scuffing and other types of damage that result in equipment failure and downtime. Protection against oxidation, thermal degradation, rust, copper corrosion and foaming is also important.
AMSOIL Series 2000 Synthetic 75W-90 Gear Lube delivers unbeatable protection and fuel economy (independent testing shows class 8 vehicles with AMSOIL Series 2000 Synthetic 75W-90 Gear Lube in the differentials obtained up to 4.83 percent more mpg than vehicles equipped with another popular gear lube).
Amsoil Synthetic Gear Lube has the film strength required to deliver all the protection heavy-duty and high-stress applications need in a fuel-saving viscosity grade. AMSOIL Series 2000 Synthetic 75W-90 Gear Lube is recommended for use in all passenger vehicles, commercial trucks and race vehicles.
AMSOIL 75W-90, 80W-90 AND 85W-140 Gear Lubes exceed the lubrication and performance requirements for gear boxes where API MT-1, GL-4 or GL-5 lubricants are specified.
--------------------------------------------------
A lot of people ask: 75w-90 or 75w-140? Personally I would use the synthetic 75w-90 since synthetic 75w-90 will perform above and beyond the recommended petroleum 75w-90.
I have Freightliner customers driving Class 8 Tractor Trailor Trucks using 75w-90 synthetic gear lube in their difs. Tuff enough for them ... Tuff enough for me.
--------------------------------------------------
Helpful Differential Recommendations:
-Flush (drain) as much of the old fluid out.
-Differential fluid capacity depends on ring gear and axle housing size.
-Do not over/under fill differential. This could mean a capacity difference of a quart or more and may cause overheating problems. (See the owner’s manual for proper fill level)
AMSOIL gear oils are formulated with friction modifiers for limited slip differential applications. There is no need to add limited slip or additional additives.
-After changing the differential fluid, drive the vehicle in 7 or 8 figure eight turns, so the new lubricant can work its way into the axle assembly.
Synthetics provide the long-lasting protection, fuel efficiency and dependability needed for top performance, even extreme-pressure conditions. Stays fluid in cold temperatures for easy cold-weather shifting.

I get a hum from the rear end on my 2wd dak sport at low speeds like driving through a parking lot. Dealer says its normal.
What do you think? Would Amsoil help quiet it down?

I had this same moaning (ghost like) noise in my 2000 QC 4x4 with the 3:55 rear. A mechanic checked it out at 40K miles and found metal filings in the oil and suggested I call Chrysler. My warruntee was up at 36K. I called customer support and talked with a nice lady there. I told her about the noise and how it had been there for a while. I mentioned that if she would check she could see from the dealer service record I had asked about it before when the truck was in for a new A/C under warruntee. I told her that I had been changing my own fluid and using high grade synth with the additive included.
After she called the dealership to inquire about my service record she came back to me and thanked me for being honest about what I had done on my own to the truck. She then said that Chrysler would cover it out of warruntee for me since it had only been 4K miles and told me I only needed to pay a $100 "deductable".
I took it in for repair the next week. The mechanic said both the clips had come off the differential clutches and the the ring gear was damaged. All of it was repaired and now the truck is fine again. I hope it doesn't need another diff at 80K though.
The Chrysler rep was very nice and very willing to make me happy. I guess at least its worth noting that if you have this going on calling them might go a lot better than you think. The customer service number is in your owner's manual.
Hope they help anyone out that needs it.

My vehicle has 31k and I noticed a chatter in sharp turns at slow speeds. Changed the fluid and used an additive designed for limited slip differentials and now the rear is quiet. No noise whatsoever.
Thanks to the insight offered on this forum I fixed the problem myself.

Took my 03 QC 4x4 in to have the backlash checked on the rear diff. this past monday. After about 45 min. the service manager calls me over and tells me that both diffs. are trashed. Rear has to be rebuilt and the front has to be replaced, and only 25,500 on the truck. They didn't make any noise that I could hear. Oh well, I'm just glad the problem was found and that it's covered by warrenty.

Slightly different issue but everyone should have their rear differential checked prior to 36,000 if possible. I own a 2002 ext cab 4X4 My ABS Sensor had come off inside the rear differntial causing metal contamination and ABS light to come on. If it had been out of warranty the labor alone would have come to $300+ let alone all the seals that had to be replaced I have a parts list with 16 different items on the bill! Turns out this little sensor doesn't hold up very well in offroad conditions. The mechanic told me extreme jarring will knock it loose.

Why are you guys paying for repairs to the differental at such low miles and only three years old. Dodge warrants the power train for 7 years or 70000 miles. Any problems that show up after 3 years or 36000 miles is repaired for $100 which is the deductable. Read your warranty.

If you have a Dodge 9.25" rear you can expect to have it rebuilt MANY times. Mine failed twice! Once at 46,000 and again at 70,000. The clutch retaining clips broke and metal destroyed all the bearings. Do yourself a favor and when it fails 1st time install an Auburn non clutch type posi.
good luck!

Just wanted to make a note and thank all of the posts
about noise coming from the rear end. I thought I was
going to need to replace my entire rear end on my 2000
DAK QC 4x4 to the tune of $1400.00 at the dealership.
However, I took advice posted here and simply drained
the diferrential oil - it was burt - put a new gasket on -
filled with synthetic gear oil - and bingo problem solved.
Thanks again for helping me save some coin!!

IP: Logged
Message:
For the DIY'er ...
The new AMSOIL Hand Pump was designed to make it easier to dispense lubes in awkward, hard to install applications. Specifically designed to fit AMSOIL quart, gallon and Twin Pack bottles, the AMSOIL Hand Pump guarantees efficient, quick dispensing of AMSOIL gear oils, transmission fluids and any oil that may need to be pumped. A larger pump and thicker hose make it possible for the AMSOIL Hand Pump to pump one ounce of fluid per stroke versus the 1/4 ounce per stroke of standard pumps. This four-fold improvement in pump efficiency saves you time and hassle.
_ 
The AMSOIL Hand Pump's versatility also makes it well suited to many automotive and marine applications, including fluid fills in differentials, transmissions, transaxles, boat lower units and boat sterndrives.
With the AMSOIL Hand Pump you no longer need to transfer your fluid to another bottle in order to dispense it, saving time and eliminating the possibility of contaminating your fluid.
The AMSOIL Hand Pump kit includes all necessary hardware such as the hose, hose clamps, a cone applicator for boat lower unit fills, 3 pick-up tubes (one for each AMSOIL bottle size) and a hose retainer clip to eliminate hose dangling and oil messes.
High quality and high efficiency make the NEW AMSOIL Hand Pump a nice compliment to the entire AMSOIL product line.
