Axle too short

I have a set of +5 and mad rhino axles for the rear. I am replacing the a arms on an 08 raze with the plus 5 high clearance arms. Front went together fine. On the rear the axles seem to be about an inch too short. I can’t stretch them out long enough to seat the axle against the inside of the wheel bearing. I have some rhino +6 rear axles from a previous kit and fully extended the +6 is 2 inches longer. Do I have an axle problem or am I doing something wrong? I have never had a problem putting axles in and I have done plenty of them. Mostly stock or rhino brand. Any advice
