2011 Pentastar axle service schedule?

I recently read a service schedule chart for my 2011 GC with the V6 motor & 3.06 gearing. It stated that the front and rear axle fluid should be changed at 36,000 mi, is this correct? It seems like it is very early to do this? My last ford explorer had a 100k mi interval on the axle fluid.

Any help or advice is greatly appreciated...

Where did you see "change"?

My Manual states: "change if using your vehicle for police, taxi, fleet, off-road or frequent trailer towing"

Re: 2011 Pentastar axle service schedule?

The maintenance schedules in the manual state to "inspect" the front and rear axle fluid every 24,000 miles and to replace if vehicle is used for police, fleet, trailer-towing, etc. So by following the manual's recommendations you should be inspecting the fluid every 24,000 miles and replacing if necessary.

On WK2Jeeps (Jeep Grand Cherokee WK2 - Maintenance information and schedules) it shows that for diff fluids should be changed every 36,000 miles for vehicles operated under "Service Interval A" and 18,000 miles for vehicles operated under "Service Interval B".

You should at least inspect your fluid at 24,000 miles and replace it if it needs to be.

Re: 2011 Pentastar axle service schedule?

I got it from the link below and it says nothing about severe usage; only to change the front and rear axle fuid at 36,000.

Having conflicting answers on here anyone know what is correct? Very strange to change a synthetic fluid at 36,000k mi. Most cars are 100k plus mi

If you don't already have it, download your owners manual and follow it as far as scheduled maintenance goes.

The page you link to does indeed address severe usage:

Service Interval "A" (Light)
Service Interval "B" (Heavy)

Depending on the model year, Jeep recommends changing it at 20k (2013-2014) or 24k (2011-2012) for severe usage. The WK2 site lists 18k, I will update that info to reflect the differences.
