I'm gonna change all my fluids... Need some advice!

JeepKj03 · Jan 6, 2010

Transfer Case will be ATF+4 i belive. They are all the same they have to meet the same standards. Some fluids are better than others becasue they put this or that in them. That is what makes them more or less expensive. You can look at this on the back of oil bottle. They will all meet the SM standards (If it has not changed) but some will add addittives and other things.

What should I put in the T case?
And is power steering fluid generic like brake?

ATF+4 in both.

If I am mistaken feel free to put me in time out, but the early KJ's actually had basic power steering fluid. It wasn't until later that the KJ's started using ATF+4 in the rack and pump.

Ive heard that too.. He has an 05 though.

JeepKj03 · Jan 6, 2010

you would be correct

sleeve · Jan 7, 2010

OK.. so just make sure you read the owners manual on the PS fluid.

Long Live the Liberty!

Well, I'm thinking I might not have enough money to do an entire fluid change, so I need to make a priority list of which fluids are most important.

Here is what I'm looking to change can you guys prioritize it for me?

Motor Oil
Engine Coolant
Trans Fluid
T-Case Fluid
Differential Oil
Power Steering Fluid
Brake Fluid

okay... make sure that I have this correct...
Transfer Case - 2Q of atf+4
Front Diff - 2Q of SAE 75W-140 mobil 1, as per my owners manual.
Rear Diff - #Q of SAE 75W-140 mobil 1 and #Q friction modifier (for the tracloc) it says 75W-90 for non towing, so which is best? Also, is RTV needed here... how much/ what kind?
Transmission - #Q atf+4 from my research I believe it to be 8 Q. What is the filter I am supposed to use? Also, is RTV needed here... how much/ what kind or should I use a gasket?

and if someone could fill in those #

RageOfFury · Jan 11, 2010

For the transmission I'd go to the dealer and let them do a proper flush/change filter/fill the ****** back up with fresh ATF+4. If you only drop the pan, your only getting a 1/3 of the fluid out.

Front diff : 1.31 QUARTS of 75W140
Rear diff : 2.19 QUARTS of 75W140 + friction modifier if the rear axle has a green TracLoc label on it.
Selec-Trac : 1.70 QUARTS of ATF+4
or
Command-Trac : 1.50 QUARTS of ATF+4

As for the RTV for the rear diff, get Permatex's Gear Oil RTV Sealant

For my own piece of mind, I'll take our Vehicle to a Chrysler dealership and have a
professional ****** flush/service done.
Yes it costs more money, but at the end of the day, it is less expensive than having
a transmission replaced.

riptricket · Jan 11, 2010

okay so I got some fluids today... $100 worth actually!!!
but if you consider they wanted $350 to do the diffs and tcase, it is worth it.

Rear Diff...

You must be registered for see images attach

Front Diff...

You must be registered for see images attach

T-Case...

You must be registered for see images attach

Now yes, I am a pest, but are these the correct fluids for my vehicle and yes I have trac lok

sharpy · Jan 11, 2010

you wont need the limited slip additive with the royal purple

riptricket · Jan 11, 2010

i just saw that it is limited slip... does that mean I need to get something different for the front? because it does not require limited slip fluid.

HoosierJeeper · Jan 11, 2010

Front is open from the factory....if that's what you were asking...

riptricket · Jan 11, 2010

i know it is open, but will that fluid work? also, should I take back the $6 bottle of LSD fluid?

ThunderbirdJunkie · Jan 11, 2010

Yes, it will work.

riptricket · Jan 11, 2010

so take back LSD bottle or keep it?

ThunderbirdJunkie · Jan 11, 2010

Can't tell if you're serious

riptricket · Jan 11, 2010

i just don't want to mess this up. i'd rather be **** and get it perfect than eff it up... ya know

ThunderbirdJunkie · Jan 11, 2010

If somebody tells you "yes you can use it"

Why would you take it back?

I'm gonna change all my fluids... Need some advice!
