This is what I can read off the paperwork;
Main oil seal...??? Something or other
Reseal pan gasket
Steering gear, steering fluid, alignment
Induction...??? Something or other
Plugs...??? Something or other
Rear Diff...??? Something or other
What I can make out is;
Engine, transmission, drive axle, transfer case
Engine cooling system
Coolant recovery reservoir
Most of that is not needed, check your manual or Jeep Grand Cherokee WK2 - Maintenance information and schedules
. Some really good reading at wk2jeeps. Most of the stuff they called out are inspection items.
-Unless you tow, transmission service not required until at least 60K (and can go longer).
-Rear differential/transfer case fluid exchange could be required at 36K, but can wait if you don't tow
-Coolant service not due until 5 years or 100K
-If V8, plugs were due at around 32-36K
-If V6, plugs aren't due until 100K
-Regarding alignment, are your tires wearing poorly? If not, probably fine until you replace the tires
-Fuel induction service not needed (use a top tier fuel and drive happy)
Sounds to me like they were trying to up sell big time ... for longevity, you can't go wrong with early fluid replacements, but according to the owner's manual, unless you tow, operate a taxi or are in very dusty areas, it is not needed at that interval.
Having said all of that, if your rear main seal is leaking, that may be covered under the 5 yr/100K powertrain warranty ... worth the question to the dealership, worst case they say is not covered.
Hope this helps.
