I've got a Snap-Off on mine at the minute and it is good but does have a downside that it introduces a small amount of play between the boss and the hub.
I'd get it checked m8
I have a snap off on mine and there is NO play or extra movement

only diffence is that the wheel is a small amount closer towards U so when indicating etc u have to stretch your fingers

lol to reach the switches lol!
ps U HAVE TO BE ON THE LOOK OUT FOR PEOPLE WALKING AROUND WITH A PIECE OF WOOD WITH 6 ALLEN KEYS BOLTED TO FIT THE BOSS SO THEY CAN STEER UR CAR AWAY
