I Grenaded my diff at the track a couple weeks ago and I am replacing it and the halfshafts early next week (as soon as I get the parts). I was wondering if it was necessary to drop the entire IRS to do this, or could I just remove the differential and halfshafts without removing the entire IRS. I have done some searches, but I just keep finding write ups on removing the whole IRS. and nothing about removing just the Diff. if anyone has done this or knows someone who has, please send some info my way. any help would be really appreciated. thanks!
