I wonder if anybody else have the same issue with the hexes on the front MIP's. The problem is when tightening the wheel nut, the hex slides inward on the axle and compresses the bearings so that the wheel can't spin freely.
No matter how hard I tighten the set screw on the hex, it won't prevent it from being pushed inward when tightening the wheel nut. I'm sick and tired of stripping grub screws.
The axles are so hard that the set screws barely put a mark in them.
On the rear I have no problems, probably because of the spacers in between the bearings.
