Replacing all Lubes
I have been using the search engine on this forum alot but I have yet to find a list of lubes that are recomended for the jk.
So far this is what I have
1. Transfer Case - Synthetic Automatic Transmission Fluid
2. 6-Speed Manual - AMSOIL Synthetic Synchromesh Transmission Fluid
3. Differentials - SAE 75W-90 synthetic gear oil
Are all these right or have i done somthing wrong?
I have read up on all the fill amounts and the techneques for doing it, so that will not be a problem.

Automatic Transmission Mopart ATF+4 Automatic Transmission Fluid
Manual Transmission Mopart Manual Transmission Lubricant or equivalent (meeting the requirements
of DaimlerChrysler Material Standard MS-9224)Make SURE you use the correct API GL rated oil in the manual transmission. I once used the wrong number and the synchros went straight to hell. The synchros need the correct additives, as defined by the API GL number.
Transfer Case Mopart ATF+4 Automatic Transmission Fluid or equivalent.
Axle Differential (Front) Mopart Gear & Axle Lubricant (SAE 80W-90) (API GL-5) or equivalent.
Axle Differential (Rear) 198 RBI (Model 35) and 226 RBI (Model 44) - Mopart Gear & Axle Lubricant
(SAE 80W-90) (API GL-5) or equivalent. For trailer towing, use Mopart
Synthetic Gear & Axle Lubricant (SAE 75W-140) or equivalent. Models
equipped with Trac-Lok require an additive.
Brake Master Cylinder Mopart DOT 3 Brake Fluid, SAE J1703 should be used. If DOT 3, SAE J1703
brake fluid is not available, then DOT 4 is acceptable. Use only recommended
brake fluids.
Power Steering Reservoir Mopart ATF+4 Automatic Transmission Fluid

One more question for yall.
I have a 4 inch rancho lift on my jk. Will i need to replace the diff cover with one that has a higher fill hole in order to get the right amount of fluid into the differentials?

It will make it easier to get the correct measured amount in there.
