differential fluid amount?

[zEus]

can someone tell me how much gear oil i would need for both my 99 dakota R/T and for my fathers 99 Ram with the same drivetrain setup( i think his would be the same as mine wouldnt it?) i cant find the info in his owners manual and mine didnt come with one

and is there an easier way to do this then taking all the bolts off ive never done this before

This is for a 2001 Dakota ,but it should be the same.

thanks.... so its 2.32 liters plus the friction modifier

Just use two and a half qts of Royal Purple Synthetic Racing gear lube and dont worry about adding any more friction modifier because it is already in there.

I used royal purple in my R/T and I am very happy with it!

[zEus]

royal purple or amsoil then scott?

[Scottcba1]

use Royal Purple........has the friction modifier right in it and you can grab it off the shelf at any speed shop and have the whole job done in less then an hour.

There are two varieties of Royal Purple one with and one without,when I went to get some for my diffs I remember they were both synthetic 75w90 but only one had the modifier,I'd double check before buying .I'm rushing out the door at the moment ,I'll check their site when I get home to clarify.

2.3 quarts, not liters. Just buy three quarts of Amsoil's finest and be done with it. :D http://www.amsoil.com/products/svg.htm.

Here is the Gear Lube that I used. http://www.amsoil.com/performancetests/gearlubetest.htm I didn't add any extra FM to my gear lube and have had no problems with the LSD in my Ram.

Yeah Zeus the 20th of November....I am DEFINITELY going. I hope to finally meet you there!

you know anything about transmissions mines starting to do like my old tranny again...... it sometimes will travel all the way up to 5800rpm and shift into neutral if i roll out the punch it then it likes to short shift on the 2-3 gear shift now errrr auto trannies are so stupid

[Scottcba1]

try adjusting the TV cable....if that doesnt work go back to that damn trans shop!

-Scott :cool:

[zEus]

but i dont want to go back to the damn tranny shop again :bawl: :bawl:

[Scottcba1]

Try adjusting the TV cable and see how that helps you.....How many miles you put on it since they had the truck at the trans shop/???

-Scott :cool:

[zEus]

5-6k..... that or its 2-3k i know it was either 89k or 86k that it went into the shop but i dont really remember

did you ever figre out how to get the old fluid out?

[bigNATEŽ]

did you ever figre out how to get the old fluid out?

take the 12-14 bolts that hold the cover on - out and pry the cover off with a flat screwdriver, pop out the fill plug, take razorblade and scrape off old RTV sealant, clean with brake cleaner and towell dry, then reapply a bead of the ORANGE RTV (which contains the high temp copper :crazy: ) let it set for 5-10 min while the oil drains out of the axle tubes, scrape the gunk(if any) out of the bottom of the inside of the pig and then clean off the mounting surface with brake cleaner and then throw the cover up there, hand tighten the bolts then bust out your handy-dandy torque wrench and set it for 20 ft lbs and go to town torquing the cover down like you would lugnuts, wait 15 min for the RTV to start to cure and then dump in the gear oil,... use no modifier if you like a stiff differential that is amost like a locker, and use 1 bottle if you like a medium to medium-light breakaway

total time to acomplish this should be 30-45 minutes
