I have a 2001 SE with ford racing lowering springs and roush struts and shocks. For some reason I keep having to replace my rear wheel bearings. I have probably installed about 4 different sets in just about 2 years. I have been torquing them to spec and my spindals are not damaged at all. I am wondering if this is a normal issue and is there a way to fix it. It have been happening even before I put the new suspension on.
