Has anyone changed there's? Is there a gasket out there? Did you replace bolts with stainless steel ones? and what type of gear oil did you use? I'm looking at synthetic (royal purple) Any feedbacks will be appreciated.

You don't need a gasket, use a good silicon gasket sealer, like Form-a-Gasket. You can replace the bolts with stainless if you want. Use any good synthetic gear oil, be sure to add Chrysler (only) friction modifyer (4 oz) if you have a limited slip.

i used mobil 1 gear oil (synthetic). Pretty easy job. Looks good. I temporarily put caps on the bolts. I have a open differential, but i added friction mod anyway. Said on the bottle it wouldn't hurt

Rock, where did you find that Differential Cover? I was thinking that while I am changing the fluid in my rear differential I might as well put a new cap on. Makes sense to me.

Well you've been digging through the old post again. I'm on here bored too

 

[GOON'S D]

Well I actually now I just got some work to do. Thank god!!!! I was not really digging however. Thought crossed my mind while I was playing solitaire on my computer and did some searching online without finding too much. So I did a search for "Differential Covers" on this site and Rock's Chrome Cover popped up. And this is pretty much what I wanted. Might as well make a nice touch up mod to my rear end while I am changing the fluid right?

why not unless your gonna get a drop then theres no point cause you wouldn't be able to see it

 

[GOON'S D]

I am not considering doing it to be flashy or anything. I could actually care less about that. More to just dress up the stock things that are on my Durango. That's all. I saw a couple for cheap on the internet so It would not be that big of a deal to swap out the old black one for a nice new chrome one or even just regular brushed aluminum. The amount of money that I will be spending on the fluid is the only thing that will really hurt my wallet.

Why Chrysler only friction modifier? I have never used the Chrysler brand stuff, just whatever is available at the local parts store for years.

every manufacturer has guidelines to fluids. transmission is ATF+4. I've been research'n and the only fluid compatible is amsoil. I was gonna put mobil 1 in, but even they're site doesn't recommend it. however I did put mobil 1 in my differential.

goon I picked it up off of ebay. I think it was $20. I like mod'n and I think it adds a nice touch. let me know if you can't find it.

remove the spare tire and get some ramps. makes the job real easy.... the smell will KYTFO

 

[GOON'S D]

What makes the fluid smell. Do you happen to know the important specs on that diff. cover? I don't want to order the wrong one if I decide to do it. I already have the ramps, just need to get the fluid, silicone, and time, and money. :jester:

 

[DirtyR/T]

didn't know they were only $20 I'd get it then. I seen some Amisol on ebay for cheap

 

[rockadaous]

the manual calls for SAE 75W-90, API GL-3. limited slip Mopar hypoid gear oil additive friction modifier. 4.4 - 4.8 pts. (12 bolt configuration) I used mobil 1. no problems

 

[GOON'S D]

I got that chrome diff cover for $16.00!!!! Not bad I think. Now I just need to get the gear oil and friction fluid. Unfortunately the cover does NOT come with bolts. So I will have to go to Home Depot or Autozone to find some stainless steel bolts to match. Does anyone know what the threads size is for these things? I would rather not go to the parts store covered in gear oil with the bolt in my hand if I can avoid it.

why not half the people in there are lol

 

[rockadaous]

I went the cheap route. I bought caps..... haven't lost one yet (2 years)

 

[DirtyR/T]

me too I have chrome caps on my tag bolts and haven't lost one since i put them on (+1 year)

 

[rockadaous]

go through here http://www.dodgetalk.com/forums/showthread.php?t=14389&page=1&pp=5&highlight=chrome+cover there's a link to the bolts. I think they're $30. sizes for the caps are in there too.

 

[GOON'S D]

I definitely think that chrome caps is the way to go. it is just easier than trying to find bolts. Plus the chrome will come off the bolts when you tighten them down and that will look like sh!t. Thanks for your help guys.

Rock, which friction modifier did you use.

Also, how often are you suggested to change the rear diff fluid.
