During the off season I will take my bow to the pro shop and have them give my bow the once over and make sure everything is up to par. Last year they greased the axle's on the wheels. For some reason a week or so later I had a squeak develop. What type of lube should I be using on my bow. Was sort of worried about WD-40 or gun oil because of the petroleum smell. Should I lube any other parts besides the wheel axle's?
