Re: Diff Cover Removal - 60K Service

2005JGC,

Lets see some oil analysis at 15k vs 30k then. If the book says 30k for schedule A then ill change it at 30k. Is there something you know that jeep doesnt?

I changed my front diff fluid in 2010. That was about 15k ago. I checked it recently and it still looked like i just filled it, golden and clear. Why change it then? Seems like a waste to me. It its ability to properly cool and lubricate the gears suddenly compromised at a magic number? Likely not.

Re: Diff Cover Removal - 60K Service

All - I just took mine to the dealer for service and asked about the differentials and was told that the new recommended service interval for them under normal use is around 80K miles - sort of confirms what Walt mentioned previously.

Re: Diff Cover Removal - 60K Service

Guys, during the last two days I have been feeling as if the Jeep is being held back. What I mean is, if I am driving and let my foot off the gas, it feels like the Jeep slows down a but quicker or like its hesitating and isn't as free feeling. I hope I am explaining it in a good way. Almost feels like I get a bit of resistance. Would this be from anything I performed this past weekend with changing out the fluids?

I was on an even surface and filled the T-Case and both front and rear diffs until it oozed out the fill out. Just want to make sure before I take any other action.

Re: Diff Cover Removal - 60K Service

The 3.7 Nag 1 combo always does a bit of that it's more than normal I gather. Chas if I remember correctly you haven't had the vehicle too long maybe you aren't used to it? It took me a little time t get used to the normal feeling from the combo. You added fluig until it seeped out correct? Do you remember how much you added to each?

No haven't had it too long just got it in January I put fluid in until it seeped out and it took all the correct amount of fluid there was a tad bit left in bottle for the front diff but not much, the rear took two full bottles and the tcase took almost the whole bottle I think there might have been a tad bit remaining of old fluid in there maybe I should open it back up but it oozed out a good bit I made sure before I sealed it up

Again to bikemobile I have an 06 srt8 at work with 50k miles on it current owner has had it about 15k miles and 3 years or so, metal in front and rear diffs, hums like a mother, the point of a service is you not get to the limit if the fluid, because once the limit is reached changing the fluid won't fix anything. But keep preaching putting off maintainence... I need the work

Re: Diff Cover Removal - 60K Service

Chas your front diff should've taken two bottles make sure your level, and double check it.
My .02 on the frequency of changing fluids is like 2005 said to always stay ahead of the curve. It cannot hurt your vehicle to change it too often. People have told me before I'm a bit crazy about these things, but most of my vehicles last me years!!!!!!!!!!

Very reassuring to hear a mechanic say that he needs thr work. Imagine that a mechanic suggesting early service intervals.

So an SRT8 is having diff problems. Imagine that.

Lets see your oil analysis from 15k vs 30k. Im curious. Ill send mine in.

Lets take a poll:

How many wk owners did not change their diff fluid every 15k but are doing just fine with over 100k miles?

Chas,

If you are anal about lube oil levels (like me), you can do the following:

Park the Heep with the nose on a slight uphill slope (like a driveway). Pull the front diff fill plug and add until it overflows and do the same for the transfer case (my fill is in the front). Then, turn it around so the nose is slightly down and do the rear diff.

Now you know that they are full.

Re: Diff Cover Removal - 60K Service

I did that with mine slightly overfilled the front diff and tcase. Then same with the rear. Just a little extra insurance in a non pressurized system.
