Wheel Hub Bearing squealing
I have a 2001 ranger edge plus, its 4x4 so my front wheel bearings are connected to a CV joint. I recently hauled a 1000 lbs. load and i did over drive off and all and i was not speeding or doing any hard breaking. But after a few days i began hearing a sort of metallic squealing coming from the front, and just like anyone else, i thought it was my brakes. I have new pads and rotors on and the squealing continued. A guy i know said that the wheel hub and bearing were shot, but i have another guy telling me mostly it has to deal with dryness of the bearing and maybe try greasing.
My question is, is there anyway to diagnose the sound, greasing, packing anything?
If so, whats the best way?
If not, whats my best option?
