I was so proud of myself. I fixed it! So I bought a cargo trailer at a good price because the tires were worn out and needed replacing. Why would anyone put locknuts on the wheels of a cargo trailer? Better yet, why did they sell it to me without the lug nut tool? My mistake! So Revane rushes to the rescue. An emergency tool kit is a lot cheaper than going to an auto parts store. I checked. So it is wise to buy here. The tool works exactly as advertised. I used a pry bar and pushed the end of the nest with my hand to get a bite. I added this because I saw that some people need an impact wrench. I'm not in my case. Back. I had to buy two, one for each wheel. Why that? Because once you've wrecked the nuts by removing them, they stay in the extraction socket forever. If you can get it out of this sucker you'll find a trick I didn't have. I caution you not to expect the worst for reuse, but expect the best for the task at hand. I hope the review gives you a piece of mind.
