8.75 Sure Grip axle end play - left side

the splines are NOT the problem... that's about 1/2 inch or more..not .060 or so.. possibly clutch sure grips have a more narrow thrust button compared to non s/g or cone... maybe some rear end guys could enlighten.. mines fixed by swapping the axel... even reinstalled the old one once more to double triple ck and it was the same still.. find another axel
