Had the plugs replaced at 75k and fuel filter, bled the brakes, should I change the fluid in the diffs, tranny, and transfer case?

What fluid is everyone using in their trannys?

From everything I see it's to my interest to just change the fluid and not 'flush' it with some sort of additive.

Worth my time to do the ball joints? or just wait till there ready to go?

What about a coolant flush? The dealer was asking me what color I had in my truck when I asked them, apparently after its first service they go from a green coolant to an orange one if I heard correctly.

Didn't really plan on doing too much, but I figured it couldn't hurt since I bought the truck used

Thanks!

 

Anyone?

Was thinking about getting a mag tech diff cover, mostly just for looks but the added oil capacity and protection is nice too

 

depending on the condition of your wallet, and the ball joints, id go ahead and replace them for a nice piece of mind.
