Grinding? How bout the wheel bearing????????????? Jack the tire up, grab the top and bottom...is there any play when you push the top then the bottom>does the wheel spin freely??? then it is the wheel bearing!!!!! it is a one piece unit. $150.00 at A WHOLESALE HOUSE. Seriously buy a good one at NAPA or the dealership $200.00+++

Check the condition of your wheel bearings. Park the truck and squat next to one of the front wheels. Grab the top of the wheel and attempt to rock the top of the wheel outward and inward. Rock it four or five times using all of your weight to pull and push the top of the tire. Any movement of the tire or any noise (clicking or grinding) will signal either impending bearing failure, or ball joint failure.
it can be any part of the front suspension or brake system including drive train damage jack up right side and with wheel still on place hands at top and bottom of wheel and push and pull in and out if movement usually a ball joint but ball joints dont give off a grinding noise ===now grab tire at the 9 and 3 position front and back -push and pull if loose possible tie rod damage or steering component damaged this also doesnt give off a grinding noise unless bent into a turning part =====turn wheel and listen and look at cv axle and around brake area if noise remove wheel and now inspect brake caliper ,brakes ,hub and axle for noise these components can give you your grinding noise repair or replace damaged components the other tests performed were for possible damaged parts since wheel was bent inward
If the noise only happens when you are moving, and it changes with the speed of the truck, its something that is connected to the wheels. Road speed does not affect suspension noises like ball joints and spindles. So it would be something like the brakes, axle joints or bearings, or something in the differential where the axles come together. If the truck is 4wd you have front hub bearings behind the brake rotors, and regular bearings if it is 2wd.
most likely a front hub [wheel bearing ]going bad but jack up front side that is causing problem and try to move tire in and out with hands at top and bottom of tire and listen and feel for noise or excess movement it to much movement remove tire an check the upper and lower ball joints as well as the shock/strut but check brakes grinding can also mean pads are metal to rotor but usually grinding and thumping is related to a bad hub
There are several components that could cause noise from the front when turning. I am assuming when you say the Front nearside you are saying the fromt left wheel is where the knocking is comming from when making a left turn. The components to be concerned about are, Wheel bearings, Ball Jionts, Tie rod Ends, CV joints and brake rotors.
Jack the car up under the control arm until the wheel is off the ground about 3 inches. Slide a pry bar ybder the tire and place the other hand on the top of the tire. As you lift and lowere the pry bar fell for loose movement in the tire. If there is such movement you have a bad wheel bearing.
Repeat the test above and watch the upper and lower ball joints for movement. Is there is movement replace the bad ball joint.
Tie Rod ends:
With the tire still off the ground grip the tire in the front and back and rey to move it as if your were trying to turn the tire. Watch the tie rod ends for loose movement. If they are loose replace them.
The Joint is housed in a rubber boot. If you can feel the joint inside the boot you can turn the tire forward and back and feel for play in the joint. If you are not able to feel the play you can loosen the clamp on the boot and push the boot out of the way. Then repeat the test.
Brake Rotors. Inspect the brakes for wear and any signs of pitting or grooves in the rotors.
You need to take this seriously because if you have a Ball joint or tie rod end break while driving, it will cause a wreck.
It sounds more like your wheel bearing. If you jack the car up in the front grab the tire at 12 and 6 and try to wiggle it. If there is movement that will prove to be your wheel bearing or your ball joint. If you have someone look under the car at the ball joint while you do it, you can single out the ball joint and tell if all the play is in your wheel bearing. Usually CV shafts are pretty resilliant, unless they click when you turn the teeth in them should be ok. They will whistle thought if there is no grease in the boot. IF one of your boots are torn and the grease is gone then you can look at the CV shaft. But as far as grinding that is something thats broken or lack of lubrication. Check the CV, but be sure to check the wheel bearing, and make sure the brakes are ok. Unfortunately without being there it makes it a little difficult to be positive. Thanks.
Sounds like the noise is a bad bearing to me. If the ball joints or tie rod ends were bad, you would have irregular steering or in an extreme case, the front end would fall apart and you would lose steering abilities.
That is a picture of a Porsche sway bar, but the idea is the same. Make sure all bolts are tight and that one end is not missing the linkage that connects it to the spring/strut. The grinding of the brakes may be the sound of the linkage piece touching the rotor. Sway bar is a logical solution to both issues.
If that doesn't fix the issue, put the front end of the truck on blocks or jack stands and have somebody wiggle the tire up/down and side to side while you inspect the mechanical components underneath. Other things to check may be the ball joints, tie rod ends and suspension bits.
