About to upgrade my axels. Now would be a good time to install my D30 Axel sleeves that I have sitting on the work bench . Has anyone installed a set from IRO? My understanding is that Ill need to pull my carrier . Was told that they fit so tightly thst all the muck from the Axel tubes will get forced into your diff housings and you must clean out before puting it all back together . I would like to install some USA Alloy oter shaft seals and wonder if the sleeves will interfere?? Welding?? Does anyone have pics?
