what gear does it have now?
how about the front?
this would be a direct bolt in,,,,and you should have no problems as long as you have the 3;08 and higher carrier,,[that you do have],,,,
i have done this a few times,,,,
you intall the pinion bearing..if it has a spacer behind it use it,,if not dont...put it together the same way it comes apart with the 3;43...also,make sure you dont mix up the spacers on the sides of the carrier..keep the right on the right and the left on the left...it should come out correct without any special spacing
if you arent going to be using the same carrier,,it will need to be set up....if using the same carrier,,you can just put the gear in and use the same spacers in the same places..and the backlash should be correct.
sense you are using the locker,,you will need to set it up with the spacers that came with the locker and do as it says in the instructions..the locker carrier is likley to be different width than the stock.....thus ,,meaning it will need to be set up..
yes...no need to remove the axle housing
