I currently purchased some 4.10 for my 99 cobra and i was wondering if anybody has a step by step explanation on how to do it...i know u need a dial indicator to measure end play and backlash but does anybody have a website that shows step by step??

 

i would let someone install it that has done it before. it would be cheaper if you drop the irs and get the hog head out and take it to them. i would also get the rear diff bushinhg from mm, and have them install it
