I have had my rack on for about 6 months. Its the standard basket. I was re torquing my bolts yesterday and i discovered this. It look it was caused by stress. Any insight would be greatly appreciated. I tried to contact Baja Rack but no answer after 5 attempts. I the sent an email with these pics asking for an explanation. Oh, I have not had anything loaded on my rack yet. Saving money for a tent. Once again thank you for any input.
