Wheel Bearings

Adjustment



The front and rear wheel bearings on these vehicles are not adjustable. If the bearings are noisy or become loose, they must be replaced.

The front wheel bearings are not adjustable. If the bearings are noisy or become loose, they must be replaced.

Cleaning & Repacking




NOTE
Sodium based grease is not compatible with lithium based grease. Read the package labels and be careful not to mix the two types. If there is any doubt as to the type of grease used, completely clean the old grease from the bearing and hub before replacing.

Before handling the bearings, there are a few things that you should remember to do and not to do.

DO the following:



Remove all outside dirt from the housing before exposing the bearing.
 
Treat a used bearing as gently as you would a new one.
 
Work with clean tools in clean surroundings.
 
Use clean, dry gloves, or at least clean, dry hands.
 
Clean solvents and flushing fluids are a must.
 
Use clean paper when laying out the bearings to dry.
 
Protect disassembled bearings from rust and dirt. Cover them up.
 
Use clean, lint-free rags to wipe the bearings.
 
Keep the bearings in oil-proof paper when they are to be stored or are not in use.
 
Clean the inside of the housing before replacing the bearing.
 

Do NOT do the following:



Do not work in dirty surroundings.
 
Do not use dirty, chipped or damaged tools.
 
Do not work on wooden work benches or use wooden mallets.
 
Do not handle bearings with dirty or moist hands.
 
Do not use gasoline for cleaning. Use a safe solvent.
 
Do not spin dry bearings with compressed air. They will be damaged.
 
Do not use cotton waste or dirty cloths to wipe bearings.
 
Do not scratch or nick bearing surfaces.
 
Do not allow the bearing to come in contact with dirt or rust at any time.
 

The rear wheel bearings on some Galant and Mirage models require periodic maintenance. A premium high melting point grease meeting Grade Multipurpose Grease NLGI Grade #2 or equivalent must be used. Long fiber type greases must not be used. This service is recommended every 30,000 miles (48,000 km).


NOTE
For information on Wheel Bearing removal and installation, refer to Section 7 of this manual.

  1. Remove the wheel bearing.
  2.  
  3. Clean all parts in a non-flammable solvent and let them air dry.
  4.  


NOTE
Only use lint-free rags to dry the bearings. Never spin-dry a bearing with compressed air, as this will damage the rollers.

  1. Check for excessive wear and damage. Replace the bearing as necessary.
  2.  


NOTE
Packing wheel bearings with grease is best accomplished by using a wheel bearing packer (available at most automotive parts stores).

  1. If a wheel bearing packer is not available, the bearings may be packed by hand.
  2.  

  1. Place a "healthy" glob of grease in the palm of one hand.
  2.  
  3. Force the edge of the bearing into the grease so that the grease fills the space between the rollers and the bearing cage.
  4.  
  5. Keep rotating the bearing while continuing to push the grease through.
  6.  
  7. Continue until the grease is forced out the other side of the bearing.
  8.  

  1. Place the packed bearing on a clean surface and cover it until it is time for installation.
  2.  
  3. Install the wheel bearing.
  4.

  17. Remove the hub, bearings and races as follows:
    NOTE
    Do not use a hammer to accomplish this or the bearing will be damaged.

    1. Remove the oil seal from the axle side of the knuckle using a small prying tool.
    2.  
    3. Remove the wheel bearing inner race from the front hub using a puller.
      NOTE
      Be careful that the front hub does not fall when the inner race is removed.

    4.  
    5. Remove the snapring from the axle side of the knuckle. Remove the bearing from the knuckle using a puller.
    6.  
    7. Once the bearing is removed, the bearing outer race can be removed by tapping out with a brass drift pin and a hammer.
    8.  

  18.  

To install:

  1. Install the hub, bearings, and races as follows:
    1. Fill the wheel bearing with multipurpose grease. Apply a thin coating of multipurpose grease to the knuckle and bearing contact surfaces.
    2.  
    3. Press the wheel bearing into the knuckle using an appropriate pressing tool. Once the bearing is installed, install the inner race using the proper driving tool.
    4.  
    5. Drive the oil seal into the knuckle using the proper size driver. Drive seal into knuckle until it is flush with the knuckle end surface.
    6.  
    7. Using pressing tool MB990998 or equivalent, mount the front hub assembly into the knuckle. Tighten the nut of the pressing tool to 144-188 ft. lbs. (200-260 Nm). Rotate the hub to seat the bearing.
    8.  
    9. Mount the knuckle assembly in a vise. Check the hub assembly turning torque and end-play as follows:

      Using a torque wrench and socket MB990998 or equivalent, turn the hub in the knuckle assembly. Note the reading on the torque wrench and compare to the desired reading of 16 inch lbs. (1.8 Nm) or less. This is known as the breakaway torque.
       
      Check for roughness when turning the bearing.
       
      Mount a dial indicator on the hub so the pointer contacts the machined surface on the hub.
       
      Check the end-play.
       
      Compare the reading to the limit of 0.002 in. (0.05mm).
       

    10.  
    11. If the starting torque or the hub end-play are not within specifications while the nut is tightened to 144-188 ft. lbs. (200-260 Nm), the bearing, hub or knuckle have probably not been installed correctly. Repeat the disassembly and assembly procedure and recheck starting torque and end-play.
