If you can't see a spot of light coming through right in the center where the axles go in, then chances are the thrust buttons/block (depending on which suregrip you have) is in there, it needs to come out.

Here is what I would do, if it's a clutch type suregrip pull the center section and knock it out. It's only held together with a pin, see here:

IF it's a cone type suregrip then the suregrip must be disassembled in order to remove the block, in that scenario it might be easier to shorten the axles a tad. You will still get good spline engagement because the green bearings allow the axle to set in just a touch more.
