differential fluid requirements
 
Im going to take off differential covers off tonight. Can anyone tell me how many oz required to refill, as i do not have a manual, and what is a good brand to go with?

any 80w90 gear oil is fine, valvoline is usually everywhere and priced well. to be safe i'd get 6 bottles 5 will cover it but its hard to get all the fluid out sometimes, it helps to pour what you can't get out into another bottle and you can usually get most of it in there.

isnt it about 2.5 bottles for each diff?

and if you have trac lock you will need the 4oz of that limited slip stuff as well..

not sure brand name.. made by mopar

plac 10-13-2009 03:24 PM

ya a tag on mine said something about LSD or fluid or something

RAGMAN 10-13-2009 03:50 PM

here it is.. straight from manual:


Axle Differential (Front) Mopar
Gear & Axle Lubricant (SAE 80W-90) (API GL-5) or equivalent.


Axle Differential (Rear)

194 RBI (Model 35) and 216 RBI (Model 44) - MoparGear & Axle Lubricant (SAE

80W-90) (API GL-5) or equivalent. For trailer towing, use Mopar

Synthetic Gear & Axle Lubricant (SAE 75W-140) or equivalent. Models equipped with Trac-Lok require

an additive.


Rubicon 216 RBI (Model 44) - MoparSynthetic Gear & Axle Lubricant

(SAE 75W-140) or equivalent. Models equipped with Trac-Lok require an additive.



doesnt say what the heck the additive is or specify weight or anything that i can find yet.

I use the lucas oil brand additive. I don't recall the specific name but someone at the parts store should b able to tell u.

i was gonna do my rear ends but then i read my tag that said "limited slip diff fluid only".. I just got the basic 80-90W gear oil, about 5 quarts. (just for rear to start with). I dont want to mess with it until I know I have the right stuff. I'll try and find some additive in my local Kragen/CSK..

is mine some kind of upgraded diff over the base, or does everyone have limited slip? Mine is a Dana 35 as far as everyone tells me. It has a rubber fill plug on the back, no metal plug.

might my front dana 30 also have that requirement or is that usually only for the rear?

You need standard 80W90 AND a little bottle of "friction modifier" for the limited slip LSD.

thanks bro.. damn is that special order? i hope i can find something generic local.

plac 10-16-2009 06:50 PM

I found this:

CRC: Equa-Torque "Limited Slip Additive" (4 fluid Ounces)

but..

Applications: Should be used in conjunction with conventional GL-5 or HP level gear oils. DO NOT USE IN AMC JEEPS WITH QUADRA-TRAC.

If here is no Jeep Dealer in your area. The Nissan LSDs use the same stuff. You can also buy it at a nissan dealer.

Your 80W-90 diff fluid should be GL-5.

You donīt have Quadra-Trac.
