Re: '02 wj differential service

so i did some research and i was partly wrong the auto parts stores does sell the friction additive mixed in sorry for the miss leading you.. the reason i said you had to get the stuff from the deal was because thats what i have always been told and have done... i talked to a mechanic at dodge and they say that the after market stuff could cause a chatter in the front diff, well that what he's seen any... thanks for the info.

Re: '02 wj differential service

Basically, I don't want to be rude but don't ever listen to anyone at a "stealership". They will tell you your missing a tire to sell you a new one...

Re: '02 wj differential service

or sell you a stock intake filter, when you have CAI.......


since your in the process of changing fluids, might aswell check the rear brakes for any diff fluid leaks, just a time saver IMO....

Re: '02 wj differential service

The quadra trac uses the 44 not the 35 in the rear. 35 in the front. The 44 has an aluminum housing or magnesium, just use a magnet on the housing and see if it sticks. Not the cover though. If it doesn't stick it's a 44. Just use a bg lube called ls2 most parts stores have it, if you have the 44, not needed in the 35.. The fluid is not important as their are only 2 manufacturers of 75-140 in the world. So no matter what bottle it's in it's the same.

Re: '02 wj differential service

Something to remember about taking the cover off. First, if the fill plug screws in, loosen or remove it first because it can be difficult to screw out once the cover is off. Also, I didn't see any comments about the magnet that I think is fixed to the inside of the cover. My 2004 had the magnet and it can pick up matelic particles from wear. It's a good idea to clean it when changing the fluid, but you cannot do it if you only suck the old fluid out through the fill hole.

No gasket needed is true. Just use RTV or the sealant they use at the "stealership". It does work good!

Good Luck

Re: '02 wj differential service

Thread bump I guess, but I need it haha

Going to be changing the fluids on both diff's tomorrow. I have the QUADRADRIVE system.

As far as I understand I need the LS additive in both the front and rear, correct?

On the topic of the brands that have the LS additive already in the gear oil (outside of RP) I don't know if anyone else noticed, but a lot of them clearly state that even though it has the additive it still is NOT FOR USE WITH JEEPS. Just food for thought it was something I noticed.

Re: '02 wj differential service

Yes, Quadra drive requires the limited slip additive in both diffs, because there is a vari-Lok differential in both. The additive permits a bit of slip in the Vari-lok, which is necessary to be able to make turns without wheel slip.

Re: '02 wj differential service

Thanks for the info Frango100

I thought so b/c the manual states the same but 2 dealers I asked said "only the front." Someone was sleeping in class


Ohhh, also when it is cold I feel resistance when I let off the throttle. Almost like driving through mud. I'm assuming this is the fluid in the drivetrain being cold, or maybe a problem?

Re: '02 wj differential service

When very cold out (around freezing or below) I have noticed that the jeep drags a little until its warmed up. I've always attributed that to cold drivetrain fluids, especially the thick oil in the diffs. We will see if things are different this year as I just refilled both diffs with amsoil severe gear 75w-140. It already seems to have less rolling resistance but that could be in my head. I chose Amsoil because I read a study that showed it maintained viscosity better at both low and high temperatures, has excellent cold flow properties, and it did not need any additive as it already contains a friction modifier for limited slip diffs. I have been running it for a few weeks now and the jeep seems to lock up well if not better than before when off road and there is no on road chatter when turning.

Re: '02 wj differential service

Hey thanks for all the info!!

Ok well the past weekend I know I said I was going to change the fluids, well I couldn't.

The person who previously changed the fluids tightened the bolts on the differentials to the point that I couldn't get them off!

In fact, I was using an air impact wrench and shattered a Snap On socket trying to get a bolt off the front diff.

So at this point I have all the fluids, just not the ability to get them in the diffs.

I was going to go to a mechanic and ask them to change out the fluids for me, but before I go....

Does anyone know how much it should cost for them to change out the fluids. I would only have to pay for labor since I have the fluids. I want to have an idea so I don't get ripped off. I mean as far as I can tell it should only be about an hour of labor to do both right? Thanks!

Re: '02 wj differential service

It took me working at a moderate to leisurely pace just over 2 hours to do both diffs a few weeks ago, but that didn't include breaking loose any over tightened bolts.
