tiki al , you may find you have put your springs on back to front , some off these lift kits come with stickers on two off the springs that say " heavy duty discovery rear " these should go on the front not the back , i've done this conversion several times and had the same thing happen . also make sure the ones you have on the front now haven't altered your dif angle to much , if they have you need to swap them around asap or you will run it dry .
also 2" is about as much as you can go without changing radius arms and trailing arms . among other things.
i put 3" lift kit on mine and it's a pain in the arse it leads to all kinds off problems .
