Diff oil?

[Brant 1]

Quick question,



I have to change the gear oil in my front and back diffs. What weight or oil should I use and how much do I need? Also can I just use RTV silicone to seal the covers or is there a gasket?

2002 4x4 w/o limited slip.

Edit: I just did a search and it worked this time... first time I did it it didnt turn up anything... a well. Looks like the back end will be simple but I might just get the front done, they only charge 44 dollars a diff anyway...

Max-Gear is recommended for use in truck, motor home / RV, and automotive front or rear differentials, manual transmissions, and lower gear units of marine engines that specify use of an API GL-5 or GL-4 fluid. All viscosities of Max-Gear are formulated with hypoid friction modifiers necessary for use in clutch or cone type differentials. No additional additives are necessary.

Can Mercon V be used for the transfer case?

 

[Todd Z]

Gavin,



I was always curious about that, But the research I have done says to just use the regular ATF...

Yeah, I thought it was curious that Ford recommends Mercon V for the transmission, but plain Mercon for the Power Steering and the Transfer Case.



Now I understand that Mercon isn't available anymore, and Mercon V says on the bottle that it is an acceptable substitute for plain Mercon. However, if it is an acceptable substititue, why doesn't Ford just recommend Mercon V in everything?

They like to keep you guessing and they like to CYA !!!
