1989 chevy 3500 4x4 454 rear brake drum removal. Does the axle bolts need to be removed

If you have drums on the rer yes you do have to remove the axle its simple though you unbolt the 6-8 bolts on the end of the axle then it just simply slides out thats it there mite be some resistance but there isnt anything else holding it in. and you dont have to worry about putting it back into the same spot eather just slide it back in and line up the drum.

its pretty simple

Remove the drive shaft

remove the tires

remove the calipers and rotors if rear disk and then remove the ebrake shoes/cables.

If rear drums remove the drums. remove the shoes and the e brake cable. remove the backing plate bolts. remove backing plate from axle and support with a piece of wire from the frame being careful not to distort the brake line.

remove the bolt that holds the breather an brake junction to the axle.

remove the break line from the tabs (may not have them).

remove the shocks from the axle.

remove the u-bolts from the axle.

pull the axle out.

Hi! sensenicht
Are there bolts on the outer hubs. If so removing the axel hub bolts will allow you to pull the axles. You should be able to remove the lock nut, lock washer and adjusting nut (second nut) to remove rear brake hubs and drums. The C-Clips are only used on the half ton and lighter cars. This is called floating axels.
Its important to replace the hub seals on the inside of the drums. A small amount of axel greese will make your brakes not work properly.

Light Duty Models

1. Raise the vehicle so that the wheel to be worked on is clear of the floor and install jackstands under the vehicle.
   
2. Remove the wheel. Remove the three retaining nuts and remove the brake drum. It may be necessary to back off the brake shoe adjustment in order to remove the brake drum. This is because the drum might be grooved or worn from being in service for an extended period of time.
   
3. Before installing a new brake drum, be sure to remove any protective coating with brake cleaner or a suitable fast-drying degreaser.
   
4. Install the brake drum in the reverse order of removal and adjust the brakes.
   

Heavy Duty

1. Raise the vehicle and install jackstands.
   
2. Remove the wheel. Loosen the rear brake shoe adjustment.
   
3. Remove the rear axle retaining bolts and lockwashers, axle shaft, and gasket.
   
4. Remove the wheel bearing locknut, lockwasher, and adjusting nut.
   
5. Remove the hub and drum assembly from the axle.
   
6. Remove the brake drum-to-hub retaining screws, bolts or bolts and nut. Remove the brake drum from the hub.
   

To install:

1. Place the drum on the hub and attach it to the hub with the attaching nuts and bolts.
   
2. Place the hub and drum assembly on the axle and start the adjusting nut.
   
3. Adjust the wheel bearing nut and install the wheel bearing lockwasher and locknut.
   
4. Install the axle shaft with a new gasket and install the axle retaining bolts and lockwashers.
   
5. Install the wheel and adjust the brake shoes. Remove the jackstands and lower the vehicle.

remove rear brake drum....There are four bolts in there. Remove these four bolts and slide out axles...Just did mine and very simple to do...

this is very hard if you do not know what you are doing. Ill try to step you through this

• pull wheels
• drain pun-kin case
• pull rear cover
• in between the spider and axle sets pull C ring with needle nose pliers
• pull hub and axle out CAREFULLY as there are roller bearings on the end of the axle housing
• pull seal out at the end of axle housing
• tap in new seal CAREFULLY and straight DO NOT BEND IT or it will be junk
• replace axle carefully as the roller bearings are still there
• replace C clip to original position
• replace axle diff cover and replace the gasket with a new one
• refill diff case
  
• install tire
• your good to go
  

To change the rear seal, yo will need to raise and support the rear of the vehicle. Remove the wheels and drums or rotors (depending on drum or disc brakes.) Remove the rear differential cover bolts and the cover (have a drain pan under the differential) You will likely need to turn the driveshaft so the center pin bolt is acessible at the back or the differential. This is a 5/16" (or 8mm) bolt that is on the right (passenger) side of the differential carrier assembly. I recommend a new bolt be installed here on reassembly. Once the retaining bolt is out, slide the center pin out enough to allow the axle shafts to be pushed in toward the center of the diff. to remove the "C" clips that retain the axle shafts in the carrier assembly. Be careful if you happen to pull the center pin all the way out not to allow the carrier assembly (has the ring gear mounted on it) to turn, as this can rotate the spider gears out of alignment causing a headache on reassembly. With the "C" clip removed the axle shaft can be pulled out of the diff. Inspect the bearing area of the shaft for rust, pitting, or scoring. Remove the old seal and carefully install the new one. Reverse proceedures to install. Take care to note the "C" clips and center pin bolt are properly reinstalled. Fill with 2.5 to 3 quarts of rear axle grease for you vehicle.
good luck.

-Remove tire and brake drum
-put drain pan under axle housing
-remove rear axle housing cover (10 or 12 bolts)
-turn gear untiil the bolt for cross shaft shows and remov e the bolt
-remove the cross shaft.
-push axle in until you can remove "U" clip from axle and axle will pull out,
Remove seal, you need a pulller to remove axle brg.

if you mean pull the axle out of the housing you must take the cover off the rear end drianing the lube at the same time and turn untill you can remove the bolt that holds the center pin you see and carefully slide the pin out far enough that you can push the axle in towards the center than remove the u shaped clip that hold it in the center, then it just slides out
