im picking up a 94 reg cab 22re 5spd 4x4in a couple of hours and wanted to know what are the first things i should do to make it a little better. i figured:

air and fuel filter
owner said he changed plugs and wires recently
differential fluid probably hasnt been changed
grease bearings



can you think of anything else?

1 question. this is my first 4x4, but i am very mechanically inclined. So, are the front and rear differential pretty much the same setup? should i change fluid in both? what about the t-case? Regular 90 weight stuff be ok?

sorry for my newbness!

 

7.5 inch diff in front standard 8 inch in the back both have drain and fill plugs...
