Buy some AAM gears. They will be just fine for what you are doing.
Did you guys not hear what Tanz said? He has to do the front and rear gears at the same time cause he is 4WD. 3.42s up front and 4.10s n the back won't work guys.
Where/who do you play soccer for? I played for 21 years, and for 2 in DIV 1 in college...
hmm i must be a something special then ,cause i just put mine in this weekend just the back only on my 04 ,and theyre working just fine.i was concerned at first,but when i went to take the driveshaft out ,to be safe i realized it was freerollin wile in park .so that tells me were good.just my 2 cents,because i had alot of people tell me the same thing,and we are here too help each other from our individual expieriences.maybe this info will help someone in a pinch or that cant afford too change both at the same time.so i would say you dont have to change both in order to swap rears.if it was a perfect world i guess it would be smart to do both,i know i would of liked to .but def. change em out b4 you push that 4wd button tho.lol.
