HANDS UP ON THAT ONE....lol I changed my Spark Plugs every 15K and front and rear differential and Transfer Case Every 15K with Royal Purple 75W90 Synthetic and transfer case with ATF+4 cause thats what it calls for and changed the Transmission fluid at 20K and will do all of those when i get except for the front end...cause i never use 4WD its hardley used except once a month when i put it in 4WD just to lube it up! but what can i say i'm very **** about my truck and keep her up even if she doesn't need it! Wish my dad felt the same way so i didnt have to sit and wonder whats going to break on my truck or look like crap or need to be repaired when i go home! ugh hate it when its in someones hands that can't even do little tasks! lol

I haven't gone more than 2500k on an oil change since I bought my truck .... lol. I get bored easily and I figure I'm hard on the truck sometimes so changing the oil can't hurt.

Whistle Pig -- what did you use to suction out your diff fluid? Also, did you suction out your trans fluid (to minimize the mess when you drop the pan)? when you change the trans fluid, did you drain and refill or flush?

BTW, your front differential spins whether you're in 2WD or 4WD, so there's no need to "lube it up" once a month.
