Review on DRIVESTAR 698-139 Left Rear Steering Knuckle for Ford Explorer 2006-2010, Explorer Sport Trac 2007-2010, Mercury Mountaineer 2006-2010; Replaces 6L2Z5B759A 6L2Z5B759AG by Sin Gabriel

It came and bent on the dust cover, no big deal so I straightened it out, installed it and within a day my wife was driving home, the brake pads and dust cover were falling apart! I had to replace the dust cover bolts (metric) and remove the brake pads as the brackets were damaged. If you're buying this part, I recommend removing the brake pads and checking that the dust cover bolts are tight. You can add Loctite to these screws, there are 4 pieces. I don't know if the pads were loosened but I would check everything and don't trust the standard manufacturers.
