Hi there. It is always a good idea to replace wheel bearings in pairs. If the center spindle nut kept coming loose, it’s possible that it was not properly torqued, or you have a spindle thread issue that should be addressed as soon as possible. In some cases, the howling sound can come from over torqued wheels or the brake caliper being loose. It’s also possible that the wheel bearings may not have been properly packed with grease. I’d recommend having a professional mechanic, such as one from YourMechanic, come to your home and diagnose your noise problem to determine exactly what’s causing this howling and to recommend the right repairs.
