please help - LOUD rumbling/scraping noise coming from front end
There is a very loud rumbling and grinding noise coming from the front end of my ranger. It is hard to pinpoint wether its form the drivers side or passenger. I can hear it at any speed, mostly when turning, even just slightly. the best way i can explain the sound is it sounds like there is a rock grinding away inside the brakes or wheels.
I have remover the brake and caliber and there doesn't seem to be anything in the way. when i spin the wheels as the truck is jacked up there is no obvious noise. only when i drive it. If I'm going downhill in neutral the noise persists. I've heard people say that it could be a bearing but it just doesn't sound like it to me (on youtube videos)...
Any ideas? I'm stumped...
thank you in advance!

Front wheel bearings hubs most likely.

^+1 Also check for the rock shield rubbing the rotor. Mine did that and made a hell of a lot of noise until I took some tin snips to it. Could be something stuck between the rotor and the shield. That's happened as well.
Last thing, make sure your caliper brackets are on right. I lost a bolt on one of mine. Made insane noise until it put a hole through the rim. Look at the inside of your rim and see if somethings been leaving a wear pattern.

Re: please help - LOUD rumbling/scraping noise coming from front end
That grinding noise while turning is most likely because the wheel bearings are worn or loose. Turning causes the short axle-shaft to bend, and the worn bearings no longer hold it in the exact center of motion. That's why the axle-shaft splines are starting to catch hold of the matching splines inside your 4x4 hubs. Also, it could also be that your axle-shaft Universal joints are worn too, which leads to the same out-of-center effect. Both are DIY repairs.

If it doesnt happen when he spins the wheel with the the rim off that leads me to believe it could be related to rim contact?

Re: please help - LOUD rumbling/scraping noise coming from front end
It could be the TELL-TALE on his brake pad itself that's grinding (by design), to tell him that his front brake pads are almost gone. Here's a photo of the little TELL-TALE on a Ranger brake pad:

If it's bearings, then it would stop making noise when he locks or just takes off the hubs, even w/o removing the rim. That "catching" I mentioned is the actual grinding noise. Spline against spline, not quite fully meshed with each other, so they catch & let-go many times per minute, which kinda sounds like poking a stick in your bicycle spokes. It also damages your hubs. Removing the weight allows the splined shaft to re-center itself, so it stays quiet.
Yes, it could be a rock behind the rotor.

Re: please help - LOUD rumbling/scraping noise coming from front end
OP in post #1 said he's had the calipers (it's not caliber) out, this naturally means he was right there looking right at the pads, etc, etc, so.....if he faithfully inspected for abnomalies and found none, then it's time to move on to the wheel bearings.

When you say turning, do you mean normal turning or at full lock? When I'm turning in a parking lot or doing a K turn on the street and get to near full lock, I get a bad grinding/rubbing noise. Little bit of a shake at 70mph and over as well, not sure if that's related

Re: please help - LOUD rumbling/scraping noise coming from front end
Normal turning. That's enough to cause it. Depends how worn your bearings are. The splines grind against each other (ie, axle-shaft splines against hub splines) cuz the flexed axle-shaft goes slightly off center. If grinding isn't a big enough red flag for you, then Youtube can show you how to wiggle your tire to check for worn out bearings.
