Stand the wheel and tire upright

with the tire outer bead in the drop

center well at the bottom of the wheel.

Insert the tire iron between the bead

and the edge of the wheel rim, and

pry the wheel out of the tire.

MOUNTING CONVENTIONAL

TIRE TO WHEEL

1.
If a used tire is being installed

remove all dirt from the tire.

If a tire is being mounted to the

original wheel, clean the rim with

emery cloth or fine steel wool. Check

the rim for dents.

If a new wheel is being installed,

coat a new valve with RUGLYDE or

similar rubber lubricant and position

the valve to the new wheel. Use a rub-

ber hammer or a valve replacing tool

to seat the valve firmly against the in-

side of the rim.

2.
Apply RUGLYDE or a similar

rubber lubricant to the sealing surface

on both tire beads. With the outer

side of the wheel down, pry the beads

over the wheel rim with two tire irons.

Do not use a hammer or mallet to

force the beads over the rim.

3.
Align the balance mark on the

tire with the valve on the wheel.

4.
Hold the beads against the rim

flanges by positioning a tire mounting

band over the tire (Fig. 7). If a

mounting band is not available, tie a

tourniquet of heavy cord around the

circumference and in the center of the

tire.
Tighten the cord with a tire iron.

Center the tire on the wheel with a

rubber mallet.

5.
Give the tire a few quick bursts

of air to seat the beads properly, then

inflate the tire to 40 psi pressure.

Check to see that the bead positioning

rings (outer rings near the side walls)

are evenly visible just above the rim

flanges all the way around the tire. If

the rings are not even, deflate the tire

completely and inflate it again.

6. When the rings are properly po-

sitioned, deflate the tire to the recom-

mended pressure.

Rear Axles — Integral Carrier Type

04-03-04

1.
Remove the wheel cover, wheel

and tire from the brake drum.

2.
Remove the Tinnerman nuts that

secure the brake drum to the axle

housing flange, and then remove the

drum from the flange.

3.
Working through the hole pro-

vided in each axle shaft flange, re-

move the nuts that secure the wheel

bearing retainer plate. Then pull the

axle shaft assembly out of the axle

housing (Fig. 2). The brake backing

plate must, not be dislodged. Install

one nut to hold the plate in place after

the axle shaft is removed.

4.
If the rear wheel bearing is to be

replaced, loosen the inner retainer

ring by nicking it deeply with a cold

chisel in several places (Fig. 3). It will

then slide off easily.

5.
Remove the bearing from the

axle shaft with the tool shown in Fig.

4 or 5. If the push-puller operation

shown in Fig. 5 is used, be sure that

the puller arms contact the flat sur-

face of the axle shaft flange rather

than the bolt heads. Also with this

method, be careful not to damage or

burr the oil seal journal as the bearing

breaks loose.

6. Whenever a rear axle shaft is re-

placed the oil seal must be replaced.

Remove the seal with the tools shown

in Fig. 8. Soak new oil seals in SAE

10 oil for 1/2 hour before installing.

7.
Inspect the machined surfaces of

the axle shaft and the axle housing for

rough spots or other irregularities

which would affect the sealing action

of the oil seal. Check the axle shaft

splines for burrs, wear or damage.

Carefully remove any burrs or rough

spots.
Replace worn or damaged

parts.

8. Lightly coat wheel bearing bores

with axle lubricant.

9. Place the retainer plate on the

axle shaft, and press the new wheel

bearing on the shaft with the tool

shown in Fig. 4 or 5. The bearing

should seat firmly against the shaft

shoulder. Do not attempt to press on

both the bearing and the inner retain-

er ring at the same time.

10.
Using the bearing installation

tool, press the bearing inner retainer

ring on the shaft until the retainer

seats firmly against the bearing.

11.
Wipe all lubricant from the in-

side of the axle housing in the area of

the oil seal before installing the new

seal.

12.
Wipe a small amount of oil res-

istant sealer on the outer edge of the

seal before it is installed. Do not put

sealer on the sealing lip.

13.
Rear wheel oil seals with syn-
thetic sealing elements have been in-

corporated in production. However,

only leather seals will be used as re-

placements for the synthetic sealing

element seals. Install the new oil seal

with the tools shown in Fig. 8. Instal-

lation without use of the proper tool

will distort the seal and cause leakage.

Be sure the new seal has been soaked

in SAE 10 oil for 1/2 hour.

14.
Carefully slide the axle shaft

into the housing so that the rough

forging of the shaft will not damage

the oil seal. Start the axle splines into

the side gear, and push the shaft in

until the bearing bottoms in the housing.

15.
Install the bearing retainer plate

on the mounting bolts at the axle

housing, and install the attaching nuts.

Torque the nuts to specifications.

16.
Install the brake drum and the

drum retaining nuts.

17.
Install the wheel and tire on the

drum, and install the wheel cover.

REMOVAL AND REPLACEMENT

OF DRIVE PINION OIL SEAL

Synthetic seals must not be cleaned,

soaked or washed in cleaning solvent.

Replacement of the pinion oil seal

involves removal and installation of

only the pinion shaft nut and the uni-

versal joint flange. However, this op-

eration disturbs the pinion bearing
preload, and this preload must be

carefully reset when assembling.

1.
Raise the vehicle and install safe-

ty stands. Remove the rear wheels and

brake drums.

2.
Make scribe marks on the drive

shaft end yoke and the axle U-joint

flange to insure proper position of the

drive shaft at assembly (Fig. 14). Dis-

connect the drive shaft from the axle

U-joint flange. Be careful to avoid

dropping the loose universal joint

bearing cups. Hold the cups on the

spider with tape. Mark the cups so

that they will be in their original posi-

tion in relation to the flange when

they are assembled. Remove the drive

shaft from the transmission extension

housing. Install an oil seal replacer

tool in the transmission extension

housing to prevent transmission leak-

age.
Refer to the transmission group

for the appropriate tool.

3.
Install an in-lb torque wrench on

the pinion nut Fig. 6. Record the tor-

que required to maintain rotation of

the pinion shaft through several revo-

lutions. \

4.
While holding the flange with the

tool shown in Fig. 9, remove the inte-

gral pinion nut and washer.

5.
Clean the pinion bearing retainer

around the oil seal. Place a drain pan

under the seal, or raise the front of

the vehicle higher than the rear.

necessary, replace the gasket.

Check the fluid filler tube connec-

tion at the transmission case or pan.

If leakage is found here, install a new

O-ring or tighten the fitting to the

specified torque.

Check the fluid lines and fittings

between the transmission and the

cooler in the radiator tank for loose-

ness,
wear, or damage. If leakage can-

not be stopped by tightening a fitting,

replace the damaged parts.

Check the engine coolant in the ra-

diator. If transmission fluid is present

in the coolant, the cooler in the radia-

tor is probably leaking.

The cooler can be further checked

for leaks by disconnecting the lines

from the cooler fittings and applying

50-75 psi air pressure to the fittings.

Remove the radiator cap to relieve the

pressure build at the exterior of the oil

cooler tank. If the cooler is leaking

and will not hold this pressure the

cooler must be replaced. Cooler re-

placement is described in the Cooling

System Section of Group 11.

If leakage is found at either the

downshift control lever shaft or the

manual lever shaft, replace either or

both seals.

Inspect the pipe plug on the left

side of the transmission case at the

front. If the plug shows leakage, tor-

que the plug to specifications. If tight-

ening does not stop the leaks, replace

the plug. On a C6 transmission, a TV

pressure plug is also provided on the

right rear side of the case.

When converter drain plugs leak,

remove drain plugs with a six-point

wrench. Coat the threads with FoMo-

Co Perfect Seal Sealing Compound or

its equivalent, and install the plugs.

Torque the drain plugs to specifica-

tion. Fluid leakage from the converter

housing may be caused by engine oil

leaking past the rear main bearing or

from oil gallery plugs, or power steer-

ing oil leakage from steering system.

Be sure to determine the exact cause

of the leak before repair procedures

are started.

Oil-soluble aniline or fluorescent dyes

premixed at the rate of 1/2 teaspoon

of dye powder to 1/2 pint of transmis-

sion fluid have proved helpful in locat-

ing the source of the fluid leakage.

Such dyes may be used to determine

whether an engine oil or transmission

fluid leak is present or if the fluid in

the oil cooler leaks into the engine

coolant system. A black light, how-

ever, must be used with the fluorescent

dye solution.

CONVERTER LEAKAGE

CHECK

If there are indications that the

welds on the torque converter are

leaking, the converter will have to be

removed and the following check

made before the unit is replaced.

A leak checking tool (Fig. 2) can be

made from standard parts. The tool

can be used to check all converters.

1.
Install the plug in the converter

(Fig. 3) and expand it by tightening

the wing nut. Attach the safety chains.

2.
Install the air valve in one of the

drain plug holes.

3.
Introduce air pressure into the

converter. Check the pressure with a

tire gauge and adjust it to 20 psi.

4.
Place the converter in a tank of

water. Observe the weld areas for

bubbles. If no bubbles are observed, it

may be assumed that the welds are

not leaking.

ENGINE IDLE SPEED CHECK

Check and, if necessary, adjust the

engine idle speed, using the procedure

given in Group 10.

If the idle speed is too low, the en-

gine will run roughly. An idle speed

that is too high will cause the vehicle

to creep, have harsh engagements and

harsh closed-throttle downshifts.
ANTI-STALL DASHPOT

CLEARANCE CHECK

After the engine idle speed has been

properly adjusted, check the anti-stall

dashpot clearance. Follow the proce-

dure given in Group 10 for checking

and adjusting this clearance.

MANUAL LINKAGE CHECKS

Correct manual linkage adjustment

is necessary to position the manual

valve for proper fluid pressure direc-

tion to the different transmission com-

ponents. Improperly adjusted manual
