Since I saw this bouncing around, I stopped on the way home and got fluid for mine. I just changed them both this evening...not too bad of a job. Getting the top bolts off the front diff is a little pain cause the PS rack is in the way, but other than that no issues.

The front fluid was thicker, almost cloudier, than the rear. It looked like the diff fluid on my old Ranger that ran 80w-90 gear oil. The rear looked brand new, but did have a few small metal flakes in the fluid. I don't have the rear LSD, so I'm guessing that's just normal wear?

BTW, the front took almost exactly 2 qts, and the rear took just over 2.5. I can't believe the service interval is 15K miles. That seems excessive, but this is only the 2nd truck I've owned.

 

What you said is true....the friction modifier os for the clutch pack on the limited slip...

 

How do I know if I have a limited slip? did they come stock off the lot?

 

There should be a label inside the glove box that says what rear axle you have. The LSD was an option.

 

I can get u an exact amount it you want, as far a fluid or diff type or anything else, call a local dodge dealership and talk to parts. All you need is your VIN number, and they can tell you what diff you have and fluid to use (as far as weight)

 

well i was gunna do it today but now that i got 3 inches of snow under the truck it may take a while to shovel it all out
