Front End grinding/knocking?
I'm having problems with a front end grinding, knocking noise. Its started doing sence having to use 4wd during the winter months. Ive checked the hubs to make sure theyre disengaged. I also checked my shocks, and front end componets for anything obvious.
The grinding seems to be from the front driver side wheel. Its on and off doing it, usually a bump or so will bring it on. The front brakes were recently done with new rotors so it dosent look to be brake related?
Thanks as allways for the help!!

Also check your swaybar link ends. You can't move them but look close at the rubber bushings. See if there is split rubber in them. You can also take them off and tie up the swaybar, then drive around and see if it still does this. I changed mine a while back because it would clunk when I hit a bump.

I thought of the swaybar too, but didn't think it would be able to be heard from inside unless the bushings were really, really hosed. Mine are worn I know but I can't hear anything while driving the truck.

I just recently solved this exact problem. It sounded like I was riding on rumble strips and I'd engage 4X4 and it would go away. Hit a bump and it started back. There is a needle bearing inside your "NON-serviceable" hub assembly that your stub axle rides in. Pull your hub assemblies off, knock the needle bearing out and go get one for each side from NAPA (Part number B2110) for $12. Do both sides and grease them every 60-80K. You should probably change the large yellow o-rings on your hub assemblies. Ford has them for $5.00 each

Wow guys thanks for the fast responses!!!
Ill tear into those bearings this weekend then, because the sound is very annoying... thanks for including the part number on those as well, having to search for this stuff can be painful.
Definitly not the ball joints, had those all redone about 4k miles ago.
Thanks again!!

ok I got the new needle bearings in, and the problem still is happening. I'm at a lost again. The knocking/rattling noise i can hear happens when ideling occasionally. The noise also happens when turning or changing lanes to the left, but goes away when going right.
Any more suggestions will be great!!

Did you check for play in the wheel bearings? Jack the truck up, wheels still on. I use a prybar and stick it thru a hole in the wheel and pry against the center of the hub. Gently pry on and off feeling for play. Sounds like one of them are going out. Sorry the needle bearings didn't fix it. Did you do both sides? When I did mine it sounded like the left side was the bad one, but actually ended up being the right

I'm thinking it isent the wheel bearings because the sound, and what i can feel is occasional and happens when im at a stop light, or when the truck is ideling. Also on my way into work today i noticed it also happens when i accelerate, when i let of the gas is go away? I imagine a wheel bearing would be all the time??
For the wheel bearing i did check them for play and to see if they were loose and they are still very tight, no noticble play at all.
So I'm not sure to say the least.
