Hmm, interesting info from your Dealer. What I posted came directly from the Dakota Service manual I downloaded from here.

I ordered that 75W-110 Amsoil Severe Gear oil the other day (I'm a "Preferred Customer-meaning I paid them $ to be one, lol) so will change mine out with that once I get it. I am a little over 16k at this point. I will spray the diff cover at that time too--Probably just satin black though (it shows minor surface rusting)--Unless I find a chromed replacement cover before the fluid change. Amsoil states that its compatible out of the bottle with LSD, but I bought a pint of the LSD additive anyways, that I'll add to the lube, so I don't have to do it later if I get chatter.

 

Might as well grab a couple of quarts of ATF as well for your transfer case.
I think I will try it as well, along with the modifier. 2 quarts and modifier is just right, other wise it takes a little ofer 2 quarts.
I am going to do all, front 75-90, rear 75-110 and tcase ATF.
18K miles here.

How much did you save using the preferred customer?

$9.70 qt for 75W-110, $5.50 LSD additive and $11.65 for EAO42 oil filter (for my next change)...I am 4X2 so no transfer case or ft diff. I will be changing tranny fluid over to Amsoil once I find a shop that has that suction machine....

 

What is this "suction machine" you so speak of? And how does it work?

I'm gonna be doing my tranny and front diff. and transfer case this week.

Explain, please?

 

I found this from : http://autos.aol.com/article/general...05115609990001

The advent of the transmission fluid exchange machine was a great step. In the past, automatic transmission fluid could only be changed by removing the transmission oil pan, which only holds three to six of the eight to 10 quarts in the transmission. The second you started the car, the new fluid mixed with the old, eliminating much of the benefit of the service.

The fluid exchange machine, which some people choose to call a flush machine, cuts into the transmission cooler line at the radiator. As the car runs, old fluid goes out into the waste tank while new fluid is simultaneously pumped in. If the shop is really thorough, the car is lifted and actually driven through all the gears while the exchange is taking place. And if the service is done properly, the transmission oil pan still has to be removed and cleaned and the filter replaced -- a solid hour and a half of work. So if a quick-lube shop is offering it to you in 35 minutes, something's not being done.

 

Ok. I rcvd the Amsoil 75W-110 Severe Duty Gear Oil today and put it in the rear diff tonight. I'm glad I did this (16,150 miles) as there was indeed a silvery tint to the bottom sludy area of the old fluid. There is a 1"x1" magnet on the bottom of the housing that catches the metal shavings that accumulate.After draining the original fluid, I sprayed the gears down with brake cleaner and wiped it down. All looks good. I will post a couple of pics. First one is of the cleaned gears, 2nd is the cover with RTV sealant applied awaiting mounting and the last is the rear cover attached and torqued to spec, with the aid of my new Craftsman Torque wrench, purchased for this project (always wanted one anyways). Pretty easy project, just a little time consuming and dirty/smelly--That fluid in the diff does not smell like motor oil--most sulfur-ey.

whats with the teeth on the ring carrier?

 

I don't know what/wherethe ring carrier is. Why, do you see something funny?

 

I have done many gear swaps and locker installsand never seen the teeth on the part that the ring gear bolts onto( pic 1). It may be part of the limited slip but that is generally clutchesin where the spider gears are. No idea I also have never done a dodge rear only dana 44 and 30 found mostly in jeeps. anyone have some imput on the mystery teeth?
