8.75 Sure Grip axle end play - left side

rub2stix, when you installed the axles did you get them seated in both sets of splines on EACH side?

This might be your issue, if you're saying one side has a gap.

Huh? They pushed i the way- enough to tighten the axles onto the backing plates. Wouldn't that mean they're seated?
