Hello - while it is possible that there are simply loose nuts/bolts for the fan, it is most likely the fan clutch is failing, hence the wobbling fan. I recommend a fan clutch replacement as soon as possible, performed by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, replace this critical component, and get you back on the road quickly.
