Did the 2002 full size Montero come with standard or synthetic fluid in the transfer case and diff's? I want to change now and can't find this info.

 

Mineral oils with additives for transfer case and rear LSD.

Mineral oil for front and rear non-LSD.

If you are doing this yourself please read the following to ensure you are aware of the SAE J306 Specifications changes affecting SAE 90 fluids.

I am running Amsoil 80W-90 in both diffs. The LSD has performed perfectly without any additives.
For the transfer case, I chose the Amsoil Severe Gear 75W-80. Gear selection is smoother and has less lag time than ever before.
Good Luck

 

Thanks everyone. I've been an Amsoil guy for 25 years and was considering that for the change. Mr. Z, you helped make my decision for me. Thanks.

 

where is the fill plug on front gear case any pics

 

Full size Montero has a big plug (hex bolt) on the front side of the front differential. That is fill plug and level indicator. Drain plug is on the very bottom.

 

Its the transfer case big hex underneath driver side suspension bar running right in front of it,so fill plug is?

 

The big hex bolt is on the very bottom but on the side facing out on driver side ,where is the fill plug relative to that position?

 

Is the same oil in front and rear differentials
