Just wanted to share some helpful advice. I am a firm believer in maintenance over fix it when it breaks. After re-packing my trailer bearings, I must not have tightened the lug bolts on my trailer tight (we all make mistakes). Anyway, entire wheel came off the trailer on the road. Now, we all carry a spare tire for the trailer, but how many of us carry extra lug nuts? I now carry an extra set of lug bolts in the truck on every trip. I figure if I have them, I won't need them. I hope none of you end up stranded on the road like I did .
