I did all the maintenance on my Liberty for the 60,000 mi. mark. Was wondering if I should change the front and rear differential fluids, and transfer case fluid. I have heard of some people doing this, I would like some more opinions. Should I use the recomended lubes and such listed in the manual if I do change them, any recomendations on other lubes. Thanks in advance for the help |

Yes. The manual recommends 12K intervals for the diffs and 60K for the t-case. I recommend 30K interval for the t-case. |

Thanks for the info. It looks to be an easy job. I would rather change everything to be safe. Thanks again |

I just did my 60,000 mile maintainance. I would strongly recommend getting the transfer case and transmission serviced. As for the diff's, it's probably a good idea to have them serviced, but if the fluid looks good, it probably won't hurt anything if you hold off. |

The sooner you get the tranny serviced(and often) the less likely of a failure after a service at high miles.I don't know about others KJ but my t-case fluid is black after 10,000miles so I change it every 2nd oil change(6000miles),it only costs me $8 and 20min do do the t-case.The low mileage for the diff service is mainly for the front diff since it doesn't hold much fluid and doesn't get much airflow for cooling(if you have skids),the rear should be changed often if you tow or offroad,if you have a LSD(factory or aftermarket,excludes the Detroit TT) in the front/rear the friction modifier is pretty shot after 15,000miles anyway. |

In the owners manual it has the recomended lube, and how to drain and refill the transfer case. But how much lube goes in the front and rear differentials. |

The front diff holds 2.6pints,the raer 8.25 holds 4.4 pints,if you have a clucth driven LSD you need to substitute 4oz of gear oil for 4oz of friction modifier(most full syn gear oils have friction modifier in it already,most but not all).So all in all you need 4qts of gear oil and will have about 1/2qt left over,the front diff has a drain plug so you do not need to remove the cover,the rear diff you need to remove the rear cover and re-apply RTV to seal it up(wait 45 min) then refill.

Thanks If you have the OEM Tracloc(LSD) you need to look on the rear axle,there should be a green tag on the right axle tube,by the right brakes backing plate,it will state the gear ratio and if you have the Tracloc or not,or you can get a build sheet from a dealer.
I have a '02 FSM,Haynes manual,and a Chiltons manual for my KJ that states capicities,but the owners manual will state the capicity of all the fluids in it,look under "capicities" in the index. |

I did all the fluids and lubes but the rear differental. I couldn't find the tag to tell me what I have. There are tags an labels all over underneath there but nothing for thr rear end. I did find out that the Jeep was built on 4-18-05 at Toledo. I guess I have an excuse to have a birthday party for my Liberty. |

can anyone do a write-up for it (transfer case) with pictures and all fluid amounts? Tranny would be an easy job if it had a drain plug. Thinking of getting one of these next time: Universal Drain plug For the transfer case pretty easy. Here is a link, not for the liberty but it has pictures and its the same concept: http://jeep.us41.org/transfercase/index.html Capacity depends on what t-case you have: NV231: 3 pints NV242: 3.4 pints |
