I made a quick video on how to change the oil front and rear differentials my 4.7L, 4X4 Grand Cherokee and thought I would share here since they have the same drive train. Hope this helps someone out if they have never done their own maintenance before!

Diff Service at Dealer

Thanks for the video.

I was at the dealer for regular maintenance and the service rep told me that I should consider getting the front/rear diff. oil changed out. I have an '07 LTD HEMI with only 25,000 miles on it.

They wanted $315.00 all in just for the diff. work.

Do you know if any warranty would be voided if I did the work myself?

Thanks

It shouldn't be voided as long as you stick with products that are approved for your vehicle and as long as you keep receipts and mileage with it. That's what I have been doing. I would still consult with your warranty provider first though. The dealer is a rip because they have to pay all the staff, plus insurance through the roof, chemical pick up fee's, blah, blah,blah. Do it yourself and return the used oil to pep boys. This took me about 30 or 45 minutes to do in my garage - well worth saving several hundred dollars in my book!

Amazing, thanks, will take a look for it. Makes sense there would be!

This next question may seem a bit stupid (as I presume ou should always keep it as level as poss) but am I able to drain the front diffs and transfer case having jacked up the front slightly so I can get under a bit easier or will that affect the drain and refill amounts badly? Probably only talking 10cm raise or something. Same for the rear diff. Thanks

The Front Diff and transfer case have drain plugs - think a 1/2 inch drive ratchet fits the diff one and possibly the transfer case. The rear diff does not have a drain plug - remove cover to drain. To put oil back in get one of those pumps that fit oil bottles - cheap at auto parts store or many retail stores.
