8.75 Sure Grip axle end play - left side

just went thru this...checked it all before assy put in new diff and dr side axle is loose even though pass side is adjusted perfectly... i had another set of axels and plopped in one of them and voila it now adjusted perfectly on both sides... i never checked the axel play before i disassembled so it may have been loose before.. but i must conclude the axel bearing is simply pressed on too far for the amount of travel the differential spacer provided..maybe the old unit had a spacer with more clearance/play [meaning it was WIDER than this one] ... but problem solved!... swap that dr axel!
