Please help
So I recently replace my rotors and pads all the way around my 2004 Ford Explorer. While doing this I realize I needed I rear left wheel bearing and the front left CV axle. I decided to go with what they call a loaded knuckle rather than replacing all the oldie brake parts and pressing the wheel bearing in and out. For $340 I was able to purchase the entire hub assembly with all mounting brackets knuckle and wheel bearing and e break Hearts all assembled all I had to do is slide it on. Saved hours on the job. After replacing all the rotors and pads and the front left CV axle everything was fine. For about 2 weeks then I hit a patch of mud on the edge of a road and had to turn the wheel to the left and steer away from the ditch to avoid the muddy soft Edge. After doing that my automatic four-wheel drive engaged pulled me out of it without incident. Within a hundred yards my ABS light came on and my 4 x 4 high light was blinking. Since then there's been a grinding you can feel in your feet that's been getting worse over the last couple days. Similar to metal on metal brake pad or a failing wheel bearing. Where do I start trying to diagnose this problem

Id guess you have one or more stones wedged into the knuckle, jack each corner and manually rotate the wheel and you’ll soon find it.
Your post read like you changed a single rear hub/brakes and a single side rotor and pads on the front, you should always renew brake components on both sides of an axle together...hope you did but thats not how I read your post.

Could the grinding you are feeling in your feet be pulsation of the brake pedal due to the ABS pump engaging? Is the "grinding" consistent in speed or does it change based on vehicle speed while the brakes are applied? When you connected the ABS sensor cables for the new loaded hub did you ensure all the weather seals for the connection were in tact, and did you make sure to fully seat the connector and tie the cabling back up the way it was from the factory? Have you removed any of the wheels and checked for obvious signs of damage yet?

Rod: and simonsi: thanks for the advice. I had been working on replacing brakes and found bad wheel bearings. While replacing hub assembly found cv axle shaft needed replacing as well as sway bar links and ball joints and tie rods/ sway bars. It's been the most wet April in New Hampshire history I think so if I wasn't working it was raining and have a dirt driveway with handstands to do my work. Well the thing that turned out to be the curve ball was the grinding and dash lights all came on suddenly after driving through muddy roadside ditch. So never did I think wheel bearing. They all usually growl for a week or two then come un****ed. So I planned on finishing my brake rotors and pads on the other side and then address what else I could find. As soon as I jacked up the new cv shaft front left side I found the bearing was junk. After replacing that hub assembly with bearing rather then pressing a new bearing into the disgusting corrosion of the old hub I cleared the codes and it ran and road as good as new. Thanks
