|Schwheelz||I really dont even have that much experiance in vehicles in general yet but my mechanical background with tools is really helping me, but this thread has gone from helpful to eye opening for me, my differentials had'nt been touched. Btw for everyone to know they were trying to sell me the service for $250 and then replace the air filter yes, THE AIR FILTER for $50 all i said was what the **** and cut my losses, i needed the evap canister and they kept saying you cant buy the plug without the canister, ripoff|

Personally, I LOVE rolling into shops like that and messing with them. Asking them questions that lead right into their "trap," then talking circles around them, but with knowledge, not lies. Very entertaining while on road trips, say Mark W.

Wow great call on that. You can save sooo much money with this.

|Work4Mud||Funny how that works, I was told the EXACT same thing at a local lube shop. They said how terrible the fluid looked in the front and rear diff, transfer case AND transmission. They wanted about $300 before tax and fees to change all of them for me, NO THANKS. Lets pretend for a second the fluids were bad, ill do it myself for a fraction of the cost.|

|thaduke2003||As daggo said, there's NO way of telling if there's water in the gear oil. They're full of shit. Unless they pulled the fill plug, and water came out, they're lying. Find another dealership, ASAP- Mark W.|

|Schwheelz||Is there anything you can put on there to tell the water/fluid concentration in the diff?|
|10-28-2010 03:18 PM|
Duh on the rest of us.
Unless the tech had xray vision of course.

|daggo66||Unless it's super contaminated, they can't tell there's water in it until it's drained.|

Ha! I had my oil changed the other day and they told me the same. I told him it had just been changed 3k miles ago, and he was dumbfounded that I even knew what a diff was, let alone that I was smart enough to get the fluid changed in it with out them telling me to.... Idiots. He also said my PS and transmission fluid need changing, but when I checked them my self they looked pretty darned good..... I hate maintenance shops sometimes.
But yea, if you've been playing in the water, then you likely need a change....

Yes it's common to get water in there.
Yes you should change it yourself.
It's not really a dealership scam; they're just hideously expensive for the book hours spec'd on this service.
I change my diff fluid at every-other oil change as part of my PM schedule. Overkill maybe but it brings piece of mind and is that easy to do.

|Peepers||You should stop fording rivers. or its possible you might have gotten some down your vent tube while wash your jeep, or a really heavy rain storm.|

FAIL!! Change it yourself for less than $20 and 20 minutes of your time. It's easy to do. No doubt they'll want $300 to change out your diff fluid. It'a a scam. Super easy to do. Check out the Diff fluid change how-to on the Project JK website.
