Ok this is the dummest thing I ever did, recently changed brake pads, all good until 2 days later I started having a grinding sound coming from the passenger side, started low but ended up seriously bad, the car was un-drivable. Took a test run with the guys that replaced pads, and they said it sounds like I need to replace bearings, then I started getting quotations for new bearings, chose the cheapest then drove the very same car very slow to fetch my friend so we could go buy the bearings. When I got there I see him staring at my passenger side wheel then he said, "WHY ARE YOU DRIVING THE CAR WITH ONLY 2 NUTS ON THE WHEEL?" I'm like what?? I checked and all the nuts were missing except for 2 and they were also loose! The damn guys from the Brakes Dealer forgot to tighten the nuts after changing pads. I've just replaced new ones and problem solved. Almost caused serious problem for nothing.
