    My sister's boyfriend wants to put lower gears in his 93 Chevy Z71. I was wondering the difficulty of putting these gears in. Not worried about the rear axle, I have done straight axles before. I am worried about the front IFS. How hard would this install be? This is a 1/2 ton truck. What size is the front ring gear, a 9.2" or a 8.2"? Also is the rear a 8.5"? Any comments or suggestions would be great. Thanks.

    i have heard that it is way easier to just buy another diff with the gears you want. To even get to the point where you would be able to change gears you will need to take apart almost the entire front end.

    Had to disassemble my friend's IFS S10 a couple of weeks ago. You don't want to do it...'nuff said.

    There a PITA. Sometimes the stub shafts dont come out. You split the cases. To get the carrier bearings out its easiest to get the races out by putting the case halfs in a parts washer and it will expand and then beat them on the ground to get them out, or run a bead inside the race and flip it over and beat it out that way. Knock the pinion races out, new races in. pinion in and set the carrier ion and bolt the halfs together, take out the vent plug, check backlash and pattern and adjust from there. NOt hard, just a pain.
