Diff. Fluid Change instructions

Anyone have detailed instructions for changing the Differential Fluid? Dealer wanted $480 and I can't swing that right now.

Jeep should be ~level, put pan under diff, loosen fill plug, unscrew drain plug, let drain, replace drain plug, unscrew fill plug, pump new diff fluid in until it just starts to run out, replace fill plug... clean up.

When draining, some use a pump through the drain hole to suck more used fluid out. Some just go in through the fill hole, less mess.

I think the fill/drain plugs are pretty obvious, but drawings are below.

That price could be for both axles, transfer case, maybe transmission.

Thanks for the info. It is possible that price could be for all you mentioned. Do you have any instructions on the transfer case as well?
Thanks.

Chrysler has a differential service coupon for many dealers for $89 per axle, special fluids and full synthetic lube extra. That's still a little more than $180. You will probably spend near $70 on mopar gear oil doing it yourself.

How often are the differentials suppose to be changed?

Most other vehicles I've had are around the 100,000 mile mark.

They've revised most when using synthetic gear oil to much shorter OCI's.



To the OP make sure you remove the fill plug 1st before anything else.If you drain the diffs and then can't get the fill plug out your SOL in a big way.

Follow your owner's manual. In 2011 Jeep recommends checking diffs every 24K miles. If you run a taxi or tow heavy frequently or drive like you stole it, change every 24K miles, otherwise they do not call for a routine diff fluid change, at least as far as they go (152K miles). Mopar synthetic lube is recommended.

Basically the same, locate the drain and fill plugs and have at it.
