Two types of axles are used on these models, the C and the non-C type. Axle shafts in the C type are retained by C-shaped locks, which fit grooves at the inner end of the shaft. Axle shafts in the non-C type are retained by the brake backing plate, which is bolted to the axle housing. Bearings in the C type axle consist on an outer race, bearing rollers, and a roller cage retained by snaprings. The non-C type axle uses a unit roller bearing (inner race, rollers, and outer race), which is pressed onto the shaft up to a shoulder. When servicing C or non-C type axles, it is imperative to determine the axle type before attempting any service. Before attempting any service to the drive axle or axle shafts, remove the axle carrier cover and visually determine if the axle shafts are retained by C-shaped locks at the inner end, or by the brake backing plate at the outer end.

REMOVAL & INSTALLATION


CAUTION Brake shoes may contain asbestos, which has been determined to be a cancer causing agent. Never clean the brake surfaces with compressed air! Avoid inhaling any dust from any brake surface! When cleaning brake surfaces, use a commercially available brake cleaning fluid.
Non C-Lock Type
See Figures 2 and 3
Design allows for maximum axle shaft end-play of 0.022 in. (0.056mm), which can be measured with a dial indicator. If end-play is found to be excessive, the bearing should be replaced. Shimming the bearing is not recommended as this ignores end-play of the bearing itself and could result in improper seating of the bearing.

  1. Remove the wheel, tire and brake drum.
  2. Remove the nuts holding the retainer plate to the backing plate. Disconnect the brake line.
  3. Remove the retainer and install nuts, finger-tight, to prevent the brake backing plate from being dislodged.
  4. Pull out the axle shaft and bearing assembly, using a slide hammer.
  5. Using a chisel, nick the bearing retainer in three or four places. The retainer does not have to be cut, merely collapsed sufficiently, to allow the bearing retainer to be slid from the shaft.
  6. Press off the bearing and install the new one by pressing it into position.
  7. Press on the new retainer.

Do not attempt to press the bearing and the retainer on at the same time.
  1. Assemble the shaft and bearing in the housing being sure that the bearing is seated properly in the housing.
  2. Install the retainer, drum, wheel and tire. Bleed the brakes.
C-Lock Type

  1. Raise the vehicle and remove the wheels.
  2. If not done already, remove the differential cover.
  3. Remove the differential pinion shaft lock-screw and the differential pinion shaft.
  4. Push the flanged end of the axle shaft toward the center of the vehicle and remove the C-lock from the end of the shaft.
  5. Remove the axle shaft from the housing, being careful not to damage the oil seal.
  6. If necessary, remove the oil seal by inserting the button end of the axle shaft behind the steel case of the oil seal. Pry the seal loose from the bore.
  7. Seat the legs of the bearing puller behind the bearing. Seat a washer against the bearing and hold it in place with a nut. Use a slide hammer to pull the bearing.
  8. Pack the cavity between the seal lips with wheel bearing lubricant and lubricate a new wheel bearing with same.
  9. Use a suitable driver and install the bearing until it bottoms against the tube. Install the oil seal.
  10. Slide the axle shaft into place. Be sure that the splines on the shaft do not damage the oil seal. Make sure that the splines engage the differential side gear.
  11. Install the axle shaft C-lock on the inner end of the axle shaft and push the shaft outward so that the C-lock seats in the differential side gear counterbore.
  12. Position the differential pinion shaft through the case and pinions, aligning the hole in the case with the hole for the lockscrew.
  13. Use a new gasket and install the carrier cover. Be sure that the gasket surfaces are clean before installing the gasket and cover.
  14. Fill the axle with lubricant at the bottom of the filler hole.
  15. Install the brake drum and wheel, then lower the car. Check for leaks and road test the car.

1977 cadillac coupe deville wiring diagram in color


Fat chance. Dealer repair manual is the only place you'll find a color diagram. Since it's a 77, I doubt you'll be able to locate the 6 rather thick manuals. ou might be able to find something online, but it won't be complete or free.

Color wiring diagram for my 1977 cadillac coupe deville incolor


Go on line and buy a manual for the car. That is the only place you will find it, if it exist. GM's diagrams were in black and white up until the 70's, I'm not sure what year they changed it, but I believe they were in color by that year.

How to remove axel on 2002 cadillac deville


this procedure is for replacing the axle bearing, it has all the info u need to do whatever it is u are doing with the axle removed.

Instructions Things You'll Need:
  • Floor jack
  • Jack stands
  • Axle puller
  • Set of 3/8-inch drive sockets
  • 3/8-inch drive ratchet
  • Needle nose pliers
  • Set of ¼-inch drive sockets
  • ¼-inch drive ratchet
  • Hammer
  • Lug wrench
  • Tube of RTV silicone
  • 2 bottles of rear axle oil
  • Bucket
  1. Step 1 Raise and support the rear of the vehicle. Remove the wheels. Remove the rear cover on the third member or axle. Place the bucket under the rear to catch the fluid. Remove the brake drums if the vehicle has drum brakes.
  2. Step 2 Rotate the outside axle until the center carrier is in a position where the small 8 mm or ¼-inch bolt is at 7 o'clock and clear of the housing so that it can be removed. This is the bolt holding the center through pin that runs through both spider gears. Position the carrier so that when the bolt is removed, the pin can be dropped straight down without contacting the housing.
  3. Step 3 Remove the center pin and lay it in the cover with its retaining bolt. Do not rotate the carrier with the pin out, since the pin is what holds the spider gears in place. If the carrier is turned, the spider gears would need to be adjusted so that they line up again with the hole for the through pin.
  4. Step 4 Push both axles in toward the carrier. This is now possible because the through-pin has been removed. This will expose the C-clips that hold the axles from coming out of the carrier. Remove the C-clips with the needle nose pliers and lay them in the pan. Pull the axles out of the housing and stand them up.
  5. Step 5 Remove the outside axle bearings and seals with the axle puller. The axle puller has several ends of different sizes; pick the one that fits through the center of the bearing. The axle puller is a sliding hammer with a T-end that can swivel. When the puller end is inserted through the bearing, rotate it slightly to get the T-end to swivel up and grab the bearing. Using the slide hammer, hammer the bearing and seal out of the housing.
  6. Step 6 Clean the housing surface where the bearing will be seated. Place the new bearing into the housing as far as it will go, and make sure it goes in straight. Place the old bearing on top of the new bearing and hit it with the hammer to drive the new bearing in. Tap it on in a circular pattern and continue until there is a resounding difference in sound as the bearing contacts the lip in the axle (it will sound more solid). Remove the old bearing.
  7. Step 7 Install the seal by tapping it carefully on four corners, avoiding the rubber part of the seal, until it is seated. Do not bend the housing or it will leak.
  8. Step 8 Install the axles and push them in all the way. Insert the C-clips on the ends of the axles and pull the axles back out to seat the C-clips in the carrier. Insert the pin back into the carrier through the spider gears and install the small retaining bolt to keep the pin in.
  9. Step 9 Clean the face of the housing and the axle cover where the gasket material will seal. Use brake cleaner or alcohol to remove all the oil from the surface to be sealed. Smear some RTV silicone sealant on the axle cover around the edge in a continuous line about a quarter of an inch thick. Allow the cover to sit until the RTV silicone sealant cures to the point that it will not transfer to the fingers when touched. The proper terminology is when it "skins," or is still wet inside but starting to dry on the outside; this way it will stay in place.

Charging problems 1977 cadillac coupe deville alt light on when you turn blower motor on car has 6900 miles on it


Likely you have one burnt diode in the alternator...If so, you will have marginal charging rate when system is not loaded and below normal rate with items such as a/c, fan or headlamps on high setting. You can check this by putting a volt meter across the battery terminals and watch the voltage. With no accessories on you should read around 13-14v. With all accessories on volts should not drop below 12.9, nor should it continue do drop over several minutes. If it does, you need to either replace diodes or replace alternator.
