My sway bar end links mounting bracket that is welded to the lower control arm keeps breaking on me the factory one broke at the weld on the lower control arm I bought a bran new control arm and that one broke near were the sway bar link goes in any ideas what would cause that to happen all the time

 

Does one side of your Blazer sit lower than the other? If the ride height is out of spec, and one side is sagging lower then it could cause excessive stress on the sway bar link. The ride height is adjusted with the torsion bar screws. Check this post for trim height specs: https://blazerforum.com/forum/tech-a...rements-38019/
