Thread: Continuos whine. (Not me, the truck.) Lol!

Mmm, i've the same kind of whine; at speed it's load dependant (unlike the 'are we there yet...')

I would prefer the Captain bring me my whine though, rather than from the other seats in the car.

Interesting about the Mobil fluid - I can get that stuff cheap.
A while ago I put a Nulon fully synthetic trans fluid in the classic Borgwarner, and it made some awefull noises. Changed it back to the Mineral stuff and it was all good.

Interesting, I was about to put a post up regarding a whine/hum mine has developed after a pretty full on and wet weekend. Sounds very similar to this, starts at 30km/hr, reduces in volume and increases in pitch as you speed up. Like you, when the load is off the driveline the noise is reduced. Changed the diff fluid and re-greased the drive shafts marginal improvement. Next will be the tranmission fluid, so is this Agrifluid is good? What Fluid would people recommend? Synthetic or mineral based? Googling reveals a wealth of issues with fluid compatibilty! Also, correct me if I'm wrong, but you don't tend to change all the fluid, merely dilute old with new so you want to be sure the new is compatible with the old??

I don't mind a hum every now and then but getting bored of this tune

Mobilfluid 424 is the 'new name' for Agrifluid 424. NOTE: it's NOT to be used in automatic transmission. more details here Mobilfluid 424.
I found several Google references (positive) to the use of Mobilfluid 424 in Jeep(1999-20xx models) transfer cases.

Having owned a 1957 Series One I thought the whine from my P38 was just normal transfer case noise

Since I have it on my to-do list, I think my transfer case is due for some MobilFluid 424 !

MobilFluid 424 seems hard to get, but the guy from Central Coast Tractors rang Castrol and they said AGRI S AF TRANS is their equivalent. $40.00 for 5 litres though he did offer me a 50 litre drum

Apparently the "S" stands for anti-squawk, probably works as anti-whine as well

Tomorrow I am servicing my ZF Transmission and replacing my diff oils etc, so the transfer case is getting some of that good juice in it !

Ahhh, I'm talking about an auto, preety sure the manual fluid would not have the desired effect has anyone has this whining/hum on their auto box? Any fluid recomendations?

Mine is an auto and i get the whine between 40 and 60 kph, I shall let everyone know what happens once i put that Agri S in it.

Was talking to an ex oil depot manager today and he was saying the mobil424 and the agri trans is a 30w dexron oil with additives for heavier duty use, but cant be used in the zf because of the type of transmission that it is.
