I am not familiar with that exact model but I am pretty sure that bearing is pressed into the knuckle. This means that you will need a press or a special set of tools in rod to press out the old bearing and press in the new bearing. If you do not see any bolts holding the bearing into place than for sure it is pressed in. What you can do is call around to various shops and machine shops to she what they charge for pressing the bearing in and out. I would bet the charge would be fairly minimal. You can then remove the knuckle from the vehicle, bring it to the shop, and let them press the bearing in and out.

    It's probably rusted on and had a pretty high torque. A half inch breaker bar with a pipe extension and a good socket might be in order. I have a pretty high performance impact wrench so axle nuts are never n issue for me. You might want to check you local auto parts store to see if they rent electric impact wrenches. That should work.

    I have a feeling you might be from the other side of the pond based on your vehicle and your post. If you are I apologize for not knowing how things are done over there.

    I will add that the proper torque spec for the axle nut is vitly important. Failure to torque it correctly will result in the premature failure of your new bearing. Also bearings should not be shopped with your wallet. You don't need the most expensive one but make sure you get a quality bearing from a reputable manufacturer.

How to take back rotors off a 1994 honda civic.

PATH: Brakes > Front Disc Brakes > Brake Disc (Rotor) > Removal & Installation Removal & Installation
  1. Raise and support the front of the vehicle on jackstands. Remove the front wheels.
  2. Remove the caliper assembly; do not let the caliper assembly hang by the brake hose, instead support it with a piece of wire looped around the front spring or control arm.
  3. Remove the retaining screw from the brake rotor and remove the rotor from the hub.

An impact driver, No. 3 phillips screwdriver bit, and a hammer may be needed to remove the retaining screw. It is fairly easy to destroy the screw slots using an ordinary phillips screwdriver to remove the tightly driven screw (see photo).

  1. To install the disc, replace the disc on the hub, screw in the retaining screw and replace the caliper assembly.

PATH: Brakes > Rear Disc Brakes > Brake Disc (Rotor) > Removal & Installation Removal & Installation
  1. Raise and safely support the vehicle.
  2. Remove the wheel and tire assembly.
  3. Disconnect the caliper from the caliper bracket. Support the caliper out of the way with a length of wire. Do not allow the caliper to hang from the brake hose.
  4. Remove the caliper bracket.
  5. Remove the two 6mm screws and the brake disc. If the brake disc is difficult to remove, install two 8mm bolts into the threaded holes and tighten them evenly to prevent cocking the rotor.
  6. Install the rotor in position. Install the two 6mm retaining screws.
  7. Install the brake caliper. Install the tire and wheel assembly.

1989 G20 Van right front brake is locking up when applied. Calipers replaced. Did not fix problem.

The piston is binding in the wheel brake cylinder, perhaps a bit of rust in the cylinder.
Inspect it, replace wheel brake piston and maybe the cylinder if you can't make it "smooth".

MX5 Front Wheel Bearing

Easy fix. Remove the wheel, remove caliper and caliper bracket. Remove brake disc. Pry off hub dust cap. This can be difficult and sometimes the cap cannot be reused. They are inexpensive, however. The hubs are not rebuildable and must be replaced. Undo the large hub nut, remove old unit, replace, reinstall nut, crimp the detent at slot in spindle. (use a punch) Nut torque is #125 ft. pounds to 160. Reinstall cap, caliper bracket, etc.
