Grinding Noise

Thank you. please I need this vehicle my wife just had knee surgery and need to get back to work.

Hello, I'm Danny.

It's hard to diagnose a sound without hearing it in person.We usually ask people to use their cell phone to make a video of sounds/noises and upload it here. Is that a possibility? Hope this helps and thanks for using 2CarPros.
Danny-

No, that don't help. it runs fine it's not the motor.

See if you can tell if the noise is front or back then jack the truck up and spin each wheel to see if you hear the noise here is a guide to help.

Please run down this guide and report back.

I was able to do a video.

The differential is junk you will need a used or rebuilt unit. thanks for the video take the guessing out of it.

Yes, the ring and pinion is destroyed.. It's possible the differential can be rebuilt/salvaged and not need an entire replacement.. Thanks again for using 2CarPros.

When driving truck makes grinding noise

With no other details or observations to go on, have the brakes inspected. Ford uses relatively soft metal for their brake rotors to reduce noise, so by the time you hear the brakes grinding, those rotors are usually worn down enough to require replacement.

My truck will make a grinding noise seem to be driver front or middle sometimes starts when a bump is hit then stops when 4x4 button is pushed inside then if pressed again will stop but usually starts again I have manual lockouts that was changed from auto hubs but sometimes can drive for several miles with no noise any ideas of what the problem is or how to narrow it down

have your brakes and axles checked

Thanks a lot for your help.You think it could be a warped rotor and would it be that hard for me to do my self I have some mechanical knowledge but am no mechanic. What would I be looking for signs of wear or damage

it cold be a warped rotor if you pedal feels like it's going up and down when braking. but it may be the brake pad warning making the noise as well, meaning it's time for a brake job. you can come to the site h ere and look on right hand side under repairs and it has a video on how to replacae front brake pads.

Well I don't feel any thing in in the pedal while breaking and why would the grinding vibrating noise came and go and stop when I engage the four wheel drive I have looked at pads and there is at least half left. No squealing noise from the brake pad clip either

we can't see it so we just give suggestions it could be rust hitting the rotor as well as that's quite common so check for that, then check the wheel bearings. Also if you see greas splattered all over by axle boots then replace the shafts as they have lost their lube. easier to replace shafts than boots and repack them. it cold also be a 4wd problem. like a transfer case. With cases like this it 's better to have a local pro look at it as they will actually hear what you have going on.

Thanks for the help

No noises whatsoever while gettin up to 4th or overdrive, but when I brake or go round a corner and try to get back into the right gear, any gear, it grinds at me. Clutch doesn't slip or try to move the truck when standing still.
I already replaced the transmission with one out of a donor f 250 my stepdad had layin around. Same situation. Could it be the transfer case? Clutch? Gotta be somethin outside trans right? Improperly bled slave or master cylinder?

Noises are more complicated to diagnose.
take your truck to an empty parking lot.
Drive in full circle( steering turned to full stop) to your right, suddently brake
drive in full circle to you left, and suddent brake
any noise?
drive straigh and brake suddently
any noise?
drive straight , change in all gears, any noise
notice for wich gear, you hear the noise.or the noise in all gear?
come back to me with what you find.

What do you mean by" clutch doesn't move the truck when standing still. "?

My truck was makin grumbly noises in 1st and 2nd. Upon inspection I found it had been leaking fluid from the concentric slave cylinder. After changing it out and bleeding the clutch, the grumbling stopped, but I started noticing that the truck didn't want to go into 3rd without grinding. I thought maybe the slave might not have been the only problem after all. But had no idea what to do about it. I drove it the way it was and it got steadily worse. By worse I mean that it started grinding whenever I tried to shift into a lower gear and it would also grind if i was traveling down hill and didn't take it out of gear. If I revved the motor the downhill grinding would stop.
Eventually the tranny gave up the ghost and just wouldn't back out of the driveway. I swapped it out with one out of my stepdads 88 f-250 which we know for a fact worked perfectly. Now that it's all swapped out and ready for the road, it's back to doin the grinding thing when I try to shift into a lower gear. Which obviously leads me to believe that it isn't the tranny, but something causing the tranny to grind.
Brake noise? Your kidding right? You just misunderstood my post?
I'm thinking misadjusted clutch pedal or faulty clutch master. But you're the experts. By "clutch doesn't move the truck when standing still" I mean that when I'm at a dead stop with the truck in gear and the clutch depressed, the clutch isn't slipping (enough?) to move the truck whatsoever.
It's been parked for a good while now and I need to get it going pretty soon cuz of the snow and hills and all.

Happy thanksgiving and thanks for reminding me the misunderstanding.
you will need to check the whole cluch assembly,
The clutch assembly consists of the flywheel, the clutch disc, the clutch pressure plate, the throwout bearing/clutch release bearing and fork, the hydraulic system and the pedal.
the hydraulic susyem was leaking, but you fixed that.
but sometime, one problem lead to another.
I suspect the trouwout bearing'
it transmits the movement of the clutch linkage and release fork to the pressure plate. it outer race depresses the pressure plate fingers or trust ring and rotate with the pressure plate when the the clutch pedal is depressed.This action causes the pressure plate to release it clamping force on the clutch disc.the inner race of the release bearing is pressed into a collar,wich slides back and forth over the transmission's front bearing retainer.

the clutch release bearing should be checked by turning the bearing while applying force in the direction of rotation.

About a month ago I replaced the steering gear box and power steering pump along with new hoses on my 1988 F-150. Everything worked great until this morning when a loud grinding noise could be heard inside the cab apparently from the power steering pump. The sound only occurs when the steering wheel is turned, however, even the slightest pull on the wheel produces the sound leaving me to believe the new pump is faulty. Am I on the right track or are there other things that could cause this? Is there something I can do to check the pump before pulling it off (as this is incredibly fun on this vehicle, ha).

Thank you for your help.

did you check the power steering fluid level? usually when the pump whines it is from low fluid or high pressure. make sure your hoses are not kinked. hope this helps. feedback and votes are very much appreciated.

The power steering fluid was the first thing I checked. It was full. The hoses are metal near the gear box and rubber coming up to the pump with no kinks or even bends. I picked up a new pump on warranty and plan to change it out this weekend unless you think it might be something else.

Also, the sound really isn't a whine as much as a growl or grind. It sounds much more severe than a whine.

Thank you for your input!

yeah id probably pop in a new pump. thats about the only thing that it can be. let us know if it fixes it.

Fords tend to have noisy steering try this, turn wheel lock to lock and see if it gets quieter when it does that, that mean theres air in the system if that doesnt do it you may have to live with it.

Recently, I try to speed up on the freeway and as soon as i am gaining some speed my truck feels as if it's skipping or grinding and i loose the speed. So i let the pedal go and i re- accelarate about 3 to 4 times just to get the speed i need. Each time I do this the same sound accures. Any ideas, I have been told that my tranny is going out.

Hi there,

This is not good, i would not be driving any further than the closest transmission specialist, get a testy & report done, the more you drive the more damage you will be doing, do this ASAP.
