Replying to Marker Jester toe piece problem

I have Marker Jesters mounted on salomon guns, with spk boots. The were mounted by a good shop too. The problem is towards the end of last season there was some play in the toe piece. The piece was screwed down right and tight, but the toe of the boot was able to move up and down about 1/8. I know I should take them back to the shop, but im going to sell them soon and would like to save the 2 hour drive to the shop. Does know whats up with the toe piece?
