Finally decided to take a look at this after washing my car. if you take a pic or a small flat head screwdriver and pry off the GTI emblem at the top(its only lightly glues on) it will reveal a 3mm allen-head bolt. simply tighten that and the top and bottom haves of the golf ball will stop rotating. wait re-glue you gti emblem until after you re-install the knob so you can make it straight! hope this helps!
