Fig. Fig. 16 Rear wheel bearing and drum on the 1979-84 Colt and Vista models

  1. Loosen the lug nuts, raise the rear of the car and support it on jackstands. Remove the wheel.
  2.  
  3. Remove the grease cap, cotter pin, nut and washer.
  4.  
  5. Remove the brake drum. While pulling the drum, the outer bearing will fall out. Position your hand to catch it.
  6.  
  7. Pry out the grease seal and discard it.
  8.  
  9. Remove the inner bearing.
  10.  

To install:

  1. Check the bearing races. If any scoring, heat checking or damage is noted, they should be replaced.
  2.  

When bearings or races need replacement, replace them as a set.

  1. Inspect the bearings. If wear or looseness or heat checking is found, replace them.
  2.  
  3. If the bearings and races are to be replaced, drive out the races with a brass drift.
  4.  
  5. Before installing new races, coat them with lithium based wheel bearing grease. The races are most easily installed using a driver made for that purpose. They can, however, be driven into place with a brass drift. Make sure that they are fully seated.
  6.  
  7. Thoroughly pack the bearings with lithium based wheel bearing grease. Pack the hub with grease.
  8.  
  9. Install the inner bearing and coat the lip and rim of the grease seal with grease. Drive the seal into place with a seal driver.
  10.  
  11. Mount the drum onto the hub, slide the outer bearing into place, install the washer and thread the nut into place, finger-tight.
  12.  
  13. Install a torque wrench on the nut. While turning the drum by hand, tighten the nut to 15 ft. lbs. Back off the nut until it is loose, then tighten it to 4 ft. lbs. If your torque wrench is not all that accurate below 10 ft. lbs. (most aren't), use an inch lb. torque wrench and tighten the nut to 48 inch lbs.
  14.  
  15. Install the lock cap and insert a new cotter pin. If the lock cap and hole don't align, and repositioning the cap can't accomplish alignment, back off the nut no more than 15 degrees. If that won't align the holes either, try the adjustment procedure over again.
  16.

Fig. Fig. 18 Tightening the rear wheel bearing nut, prior to bearing adjustment-1985 Colt

Special tools are needed for this procedure.

  1. Loosen the lug nuts. Raise the rear of the car and support it on jackstands.
  2.  
  3. Remove the wheel.
  4.  
  5. Remove the grease cap.
  6.  
  7. Remove the nut.
  8.  
  9. Pull the drum off. The outer bearing will fall out while the drum is coming off, so position your hand to catch it.
  10.  
  11. Pry out the oil seal. Discard it.
  12.  
  13. Remove the inner bearing.
  14.  

To install:

  1. Check the bearing races. If any scoring, heat checking or damage is noted, they should be replaced.
  2.  

When bearings or races need replacement, replace them as a set.

  1. Inspect the bearings. If wear or looseness or heat checking is found, replace them.
  2.  
  3. If the bearings and races are to be replaced, drive out the races with a brass drift.
  4.  
  5. Before installing new races, coat them with lithium based wheel bearing grease. The races are most easily installed using a driver made for that purpose. They can, however, be driven into place with a brass drift. Make sure that they are fully seated.
  6.  
  7. Thoroughly pack the bearings with lithium based wheel bearing grease. Pack the hub with grease.
  8.  
  9. Install the inner bearing and coat the lip and rim of the grease seal with grease. Drive the seal into place with a seal driver.
  10.  
  11. Mount the drum on the axleshaft. Install the outer bearing. Don't install the nut at this point.
  12.  
  13. Using a pull scale attached to one of the lugs, measure the starting force necessary to get the drum to turn. Starting force should be 5 lbs. If the starting torque is greater than specified, replace the bearings.
  14.  
  15. Install the nut on the axleshaft. Thread the nut on, by hand, to a point at which the back face of the nut is 2-3mm from the shoulder of the shaft (where the threads end).
  16.  
  17. Using an inch lb. torque wrench, turn the nut counterclockwise 2 to 3 turns, noting the average force needed during the turning procedure. Turning torque for the nut should be above 48 in. lbs. If turning torque is not within 5 inch lbs., either way, replace the nut.
  18.  
  19. Tighten the nut to 75-110 ft. lbs.
  20.  
  21. Using a stand-mounted gauge, check the axial play of the wheel bearings. Play should be less than 0.2mm. If play cannot be brought within that figure, you probably have assembled the unit incorrectly.
  22.  
  23. Pack the grease cap with wheel bearing grease and install it.
  24.
