Need help with spider gear ??
the jeep is at the mechanics now on the hoist. the jeep is a 91 yj 4.0 with 3.07 gears. i bought a set of 4.10's and carriers off someone on jf and we are having them installed. the new gears did not come with spider gears. they are factory gears out of a 4cy. yj. problem is i dont know what year. the spider gears from my 91 i am trying to use in the new carrier are too big of a diameter to seat into the carrier......what do i need, a new carrier or new spider gears? would a carrier with abs ( if the donor jeep was 93 or newer) be a smaller diameter for the spider gears? please help!!!!!
