My 97 chevy k 1500 makes a loud roaring noise and feels like front brakes are being applied only in 4hi or4lo any idea s


Jack up the front wheels and check for loose play in the hub bearings. Excessive play in the bearings allow the rotors to ride at an angle against the brake rotor creating drag. The roaring is the bearing itself that has failed.

Front right tire makes a grinding noise , hub assembly has been replace problem stills there, what will be the problem?


It could be a lemon replacement hub or it could actually be the tire. Check the tires tread for irregular wear patterns. If the hub was loose prior to change this could easily cause the tire to wear in a "choppy" fashion which can also cause a rough humming sound that I have often heard customers refer to as a grinding sound.

How do I change front hub and bearing assembly on 2004 Explorer


Front hub bearing, remove tire, remove caliper and caliper holding bracket, you do not have to remove brake caliper from brake hose, just set it aside, if 4X4 remove front axle nut that goes through center of rotor, also remove brake rotor, disconnect elec, A.B.S connector, remove three bolts on back side of hub bearing, remove hub bearing, some times you will need to knock hub bearing out with a hammer.Reverse to install new hub bearing.

NOISE IN THE FRONT LEFT WHEEL ON A 1999 SUBARU OUTBACK , BRAKES AND ROTOR HAS BEEN REPLACED


if the front brake pads,rotor and more importantly the caliper were all installed correctly, this noise is probably a front hub bearing that is failing. they will start a humming noise and then a roaring/growling noise the worse they get. is the noise rotational? by that it will get louder and higher in pitch as you increase the vehicle speed. get it checked out right away to avoid possible further damage.

Removal & Installation
  1. Remove 2/3of the brake fluid from the master cylinder.
  2. Raise and support the vehicle.
  3. Remove the tire and wheel assembly.
  4. Remove the front wheel hub extension (dual wheel vehicles only).
    • Insert a drift or large screwdriver through the brake caliper into one of the brake rotor vanes in order to prevent the rotor from turning.
    • Mark the relationship of the front wheel hub extension to the hub
    • Remove the front wheel hub extension bolts
    • Remove the front wheel hub extension from the vehicle. It may be necessary to tap around the perimeter of the hub extension with a rubber mallet to loosen it from the hub
  5. Mark the relationship of the rotor to the hub.
  6. Remove the caliper and mounting bracket as an assembly.
  7. Hang the caliper and the mounting bracket assembly from the suspension using mechanics wire.
  8. Remove the rotor.
  9. If the rotor is difficult to remove due to corrosion in the hub area use the following procedure to remove the rotor (25 series only).
    • Clean all the surface areas and the threaded holes of contamination
    • Generously apply penetrating oil or the equivalent to the hub/rotor area
    • Insert (2) M10 x 1.5 bolts (jack screws) into the threaded holes of the rotor
    • Tighten both bolts evenly to force the rotor from the hub.

To install:
  1. Clean all rust and contaminants from the both side of the rotor and the hub flange.
    NOTE If the rotor was removed using the jack screw method you must ensure that the hub flange is free of nicks or marks caused by this procedure. Remove all raised nicks or marks before installing the rotor.

  2. Install the rotor.
  3. Install the caliper and the mounting bracket as an assembly.
  4. Install the tire and wheel assembly.
  5. Remove the safety stands.
  6. Lower the vehicle.

  1. Raise vehicle on hoist.
  1. Remove wheel and tire assembly. Be careful to avoid damage or interference with caliper bleeder screw fitting and front disc brake rotor shield (2K004).
  1. ani_caut.gif CAUTION: Handle front disc brake rotor (1125) and disc brake caliper (2B120) assembly in such a way as to prevent deformation of front disc brake rotor , and nicking, scratching or contamination of brake linings/rotor surfaces.
    NOTE: To prevent damage, do not allow disc brake caliper to hang by the front brake hose (2078) .


    Remove caliper anchor plate bolts and discard. Position disc brake caliper out of the way. Prevent separation of caliper housing from anchor bracket because contamination of guide pin journals can occur.
  1. NOTE: If excessive force must be used during front disc brake rotor removal, the front disc brake rotor should be checked for runout prior to installation.


    If additional force is required to remove front disc brake rotor , apply Rust Penetrant and Inhibitor F2AZ-19A501-A or equivalent meeting Ford specification ESR-M99C56-A on front and rear rotor/hub mating surfaces. First, strike front disc brake rotor between lug bolts (1107) with a plastic hammer. If this does not work, attach 2-3 Jaw Puller 205-D027 (D80L-1013-A) or equivalent and remove front disc brake rotor . Remove front disc brake rotor from wheel hub (1104) assembly by pulling it off the lug bolts.
Installation
  1. If original front disc brake rotor is being installed, make sure rotor braking and mounting surfaces are clean.
  1. ani_caut.gif CAUTION: Failure to clean rust and foreign material from rotor and hub mounting faces when installing new or old front disc brake rotors will result in high rotor runout, which will speed up the development of brake roughness shudder vibration.
    Apply a small amount of Silicone Brake Caliper Grease and Dielectric Compound D7AZ-19A331-A or equivalent meeting Ford specification ESE-M1C171-A to pilot diameter of front disc brake rotor.
  1. Install front disc brake rotor on wheel hub assembly.
  1. Install disc brake caliper and new caliper anchor bracket bolts on front disc brake rotor . Tighten caliper anchor bracket bolts to 88-118 Nm (65-87 lb-ft).
  1. ani_caut.gif CAUTION: Failure to tighten lug nuts (1012) in a star pattern may result in high rotor runout, which will speed up the development of brake roughness, shudder and vibration.
    Install wheel and tire assembly on vehicle. Tighten lug nuts to 115-142 Nm (85-104 lb-ft) using Rotunda Accutorq® Lug Nut Socket 164-R0303 or equivalent on a 1/2 inch air impact wrench, or use a torque wrench.

Check the condition of the wheel bearings, front and back side if the brake rotor, and the back side of the rim. Everything should be clean, rust build-up can throw everything out of true. The hub or wheel-bearing should be tight and smooth when spun.

You must replace wheel bearings in pairs to avoid loading the old bearing and, in time ruining your new bearing hub it is possible that you have already damaged the new hub
