Thanks "God_help_me".Just asked because here in Portugal 1Lt of Mopar Nv247 costs 73€+vat and 20 Lt Mobil 424 costs 88+vat,so i am buying 20Lts of mobil that i will not use!I´ll try to resell the rest.I had it serviced for

It sounds like the QDII clutch is binding aka chattering.
That sounds like a very high quality oil (based on the spec-sheet.), and has friction modifiers for LSDs... but getting the "right" pre-mixed diff oil seems to be hit-and-miss.

The official factory technique is to use "plain" non-LSD diff oil (no friction modifiers.), and add the specified quantity of mopar friction modifier until the desired level of chatter (ie, none noticeable.) is achieved.

But, most of us here are using pre-mixed LSD oils successfully.
I use Penrite Pro Gear Full Synthetic 80W-140 - Which you probably can't find in Portugal.

Oh sorry I just noticed you have a WJ/WG not WH/WK.

My understanding is that the WJ (Quadra-Drive 1 diffs) is more prone to chatter because the gerotor pressure isn't controlled via a solenoid (in QDII the clutch-pack is only pressurised when the solenoid is activated.).

Your best-bet is probably to find a compatible friction modifier (I'm sure FUCHS would tell you.) and add small quantities to the oil until the diffs run smoothly.

You should add in small quantities though, so that you have "just enough", otherwise you'll reduce the amount of locking you get from the diffs.

The problem isn´t in the tranfer case?I used the FUCHS Titan sintopoid ls 75W-140 in the TC and in the diffs the Castrol Syntrax LS 75W140...2.7crd QDII
