just sounds like you got a cheap hub, try a pricey one

 

I would say before you go looking for loose grounds buy the timken with a lifetime warranty so if it goes bad just go get another one. I replaced both of my front hubs with timkens about 30k ago and I have had no issues whatsoever.

yeah i think im gonna... i gotta wait to get paid first... but the guy at napa swapped my hub for the pass side and its mint... he just switched boxes... and yeah
