cracking the rear axle nut
- Thread starter badger27
- Start date
I had no trouble loosening the nut, but I did use a breaker bar. If I had trouble, I would just use a longer bar. My breaker bar is homemade. It's a hollow brass tube that fits over my half inch socket wrench handle, but I still have less than 2 feet from my hand to the axle nut, so if I did have trouble, I would need a longer breaker bar. You could try penetrating oil or even WD-40 or heating the nut too. I have occasionally had to do that but that was with nuts that had stripped threads after which I had to replace both the axle nut and the axle. Just try a longer bar to get more leverage. When the axle nut releases it isn't like a sudden release such as with the oil plug either. It's slower than that with continued resistance until you get the axle nut much looser.

spray with plus-gas leave for 5 minutes then it will crack no problem. much better than wd-40.
