My dealer just gave me a quote of approximately $289 plus tax to service both differentials. If that price is correct and the cost of the lube is $70 a quart..... man, I think that will be a dealer job for sure..... unless lube is a lot cheaper elsewhere.
When I changed my fluids not too long ago, my front diff drained 45 ounces from the factory fill, and was actually slightly overfilled as it poured out of the filler plug when removed.
Mine took 44 ounces to refill, it did not want any more. I subsequently checked it a couple of weeks ago, it was still full to the bottom of the filler plug.
All your other capacities jive with what came out of mine.
I pulled this up for the tranfercase from a Chrysler Techs handbook
Grand Cherokee SRT8
Transfer Case Fluid Service
The Grand Cherokee SRT8 will be arriving at
dealers any day now and we wanted to remind
you that it will introduce a new transfer case, the
NV146. There are a couple significant differences
with the fluid and fill level on this transfer case
compared to other Grand Cherokees.
First, t he fluid full l level is 1-1/8 inches below the
bottom of the fill plug. This is different from the
other Grand Cherokee applications. Second, the
proper fluid is Mopar NV146 Transfer Case Fluid
(Part number 68001758AA). This fluid is also
different from other transfer case applications,
and any other fluids are not recommended. It is
important that the transfer case not be overfilled
and that the correct fl ui d i s used. This is important
information for the people doing PDI on these
vehicles and anyone who services these transfer
cases. Past experience has shown us that having
the fluid fill level below the fill plug can cause
some confusion.
I did my front and rear differentials at home with 4 quarts of synthetic gear lube from Wal Mart for $10.00 per quart. I don't know the brand but it seems to be working. You will need 2 different tools to remove the drain plugs, the rear takes a square drive ratchet but the front has a drain and fill plug that take a big metric allen wrench, for which I had to buy a whole set at Sears for $40.00 just to get the one tool I needed. The fill hole is in a tight place on the front of the front differential and I had to remove the allen part of the tool from the 1/2" socket and turn it with a wrench to use it. It was a pain but I got it done for $80.00, versus almost $300.00 at the dealer!
I just changed mine. You have to use the Mopar transfer case fluid. For the front/rear diffs, I used that Royal Purple stuff. I can honestly say changing all those fluids really quieted my Jeep down. I used to have this loud muffled noise when I punched it, coming from underneath the Jeep. Now I dont hear a thing, only the engine and exhaust. Hope this helps.
anyone got a DIY with pics for the transfer case/diff installs? where drain plugs are exactly...if anything needs removal...how long to wait for drains..etc
where are you guys coming up with 2 quarts of transfer case fluid?
I just changed mine today and I only pulled out 1 quart, and put back in 1 quart of fluid from the dealer. The dealer also told me it shouldn't take more than a quart anyways.
Idk why the dealer would tell me that 1 quart is more than enough.
Do you guys fill those cases up til it starts overflowing and then levels itself off?
I just wanna make sure I don't **** up that transfer case.
Fill level is 25-35mm (0.98-1.38 In.) below the bottom of the fill plug. You have to fashion a dipstick from a piece of rod, putting a 1.5" or so right-angle bend at the end. I made one and painted the end flat white, as on the rod piece I originally used (from coathanger) the oil would run right off it making it hard to measure the level.
I assume you drained the fluid while it was warm/hot, and let it drain 15-20 min.?
Looks like the dealer put limited slip additive in with the axle fluid.... Besides being inappropriate for our model, is it going to hurt anything staying in there or do I need to get them to replace it all?
