30K Mile Service Question (Dealer to do service)

Hi Everyone.

I purchased a CPO 2007 Grand Cherokee Limited at the end of January. It currently has 20,950 miles on it.

1) I am looking at the manual and it says at 15K miles it needs a front/rear axel differential fluid change. I have no idea if the vehicle received that service or not since it was not in my possession. How important is this? the car is easily 5K miles over on this service. The car has never been off-road and has been driven fairly lightly (in stop and go traffic 50% of the time. the other 50% is free flowing suburb streets).

2) Should I just wait until the 30K mile service where they change the front/rear axel differential fluid AS WELL as the transfer case fluid and spark plugs?

3) How much did your 30K mile service cost on your Grand Cherokee?

4) I have a fluid evacuator (you know the thing that will suck up the fluid through the fill holes). Is it easy enough for me to do the front/rear differential with the evacuator?

6) what do you suggest I do with my dilema of being in limbo between the 15K front rear diff fluid change and the 30K mile service. I'm sort of in the middle but again I dont know if the previous owner did a 15K mile front/rear diff change (I dont think they did).

7) finally, the car is up to date on oil changes - I am running synthetic oil...does anyone see any problems with that necessarily? I've never owned a jeep/truck before and I'm used to putting synthetics in my sportier sedans/coupes.

53 views and no one has an opinion? I find that hard to believe...

I'm pretty sure that the service department can pull your vin number and see if any services have been done at any dealer in the past. I would check that first.

The diffs can go 30k under normal conditions, 15k for heavy duty use. The rear is easy to suction out, although most of us take the diff pan off and clean it out/reseal. The front dif and transfer case need a 14mm hex wrench, but otherwise is pretty easy to drain out and refill.

I would wait until 30k for all of this. DIY, it's way too easy a job to let the dealership screw it up and overcharge you. I assume you have the 4.7. Use synthetic gear oil for front and back, no additive needed. get the transfer case fluid at the dealer, take your vin in and make sure it's the right stuff.
