I never changed my wing bolts, and I had no problems to date after 2 yrs... But I asked
this very question on a set that's on my UCD... (and I have to say I am one that always
says... Ahh just a little more...*#%*!!! [:@]... Seems like I'd have learned better after a
few auto wheel stud replacements because of the same thought ) Club members had about
the same answers as above... I get mine from Ace hardware, the price is not bad... So I am
going to start and replace them say twice a year....
