spring to shackles and loosely install shackle lower

bolt and nut.

NOTE: When installing spring, make sure

spring is positioned so that parking brake cable

is on underside of spring.

4.
Raise front end of spring and position bracket to

underbody. Guide spring into position so that it will

index in the axle bracket and also make sure that

the tab on spring bracket is indexed in slot pro-

vided in the underbody.

5.
Loosely install spring-to-underbody bracket.

is indexed on locating dowel. Upper cushion and
8. Place lower mounting plate over locating dowel on

spring lower pad and loosely install retaining nuts.

9. If new mounting plate was installed, transfer parking

brake cable retaining bracket to new plate.

10.

loosely install eye bolt and nut - head of bolt should

be toward front of vehicle.

11.
Position parking brake cable in retaining bracket and

securely clamp bracket to retain cable.

12.
Remove stand jacks and lower vehicle so that weight

of vehicle rests on suspension components. Torque

all affected parts to specifications.

SHOCK ABSORBER

Chevrolet and Chevelle

Removal

1.
Raise rear of vehicle and support rear axle

assembly.

If equipped with superlift shock absorber, disconnect

air line from shock absorber.

Disconnect shock absorber at upper mounting bracket

by removing the two retaining bolts. Refer to Figure

26 for shock absorber mounting details. (Chevelle

components shown as typical.)

Disconnect shock absorber at lower attaching bracket

and remove shock.

NOTE: When performing any service opera-

tions that requires removal or loosening of the

lower attaching nut, it is essential that the stud

be prevented from turning. A hex is located on

the stud between the axle bracket and shock

absorber in order that a wrench may be used

for this purpose. Failure to hold the stud in

this manner will result in damage to the mer

chanical bond between the shock absorber bush-

ing and the mounting stud.

tighten J-21058-8 to withdraw bushing from con-

trol arm. Refer to Figure 35 for installed view

of tools.

d. Disassemble tools and position Installer Adapter

J-21830-2 on flanged end of new bushing. Posi-

tion bushing in control arm making sure of cor-

rect installation. Small end of bushing will pass

through one side of arm without any interference.

J-21058-8 on threaded end of J-21058-15 as

shown in Figure 36. Tighten J-21058 to main-

tain proper relationship of parts; then position

Spacer J- 21830- 3 over bushing and between sides

of control arm.

specifications.

Chevelle Upper and Lower

Removal

NOTE:
If both upper control arms and both

lower control arms are to be removed at the

same time, remove both coil springs as outlined

under "Coil Spring Removal".

1.
Raise vehicle to a height that will allow axle assem-

bly to hand freely and position supports under both

frame side rails.

2.

However, the lower control arm bushings are of a dif-

ferent rubber material and are not interchangeable with

the upper bushings. Replacement procedures are in-

dicated below.

1,
Replace the control arm installed bushings as

follows:

a. Position control arm in a vise, or other suitable

holding device, so that clamping action is against

closed section of control arm.

b.
Place Puller Screw J-21058-15 through Puller

Adapter J-21474-2. Position puller screw through

small end of bushing then install Receiver

J-21474-5. Thrust Bearing and Nut J-21058-8

(in that order) onto puller screw. Install Spacer

J-21474-1 between sides of control arm and over

bushing so that spacer follows contour of bushing.

Refer to Figure 37 for installation of removal

tools.

c. Turn Nut J-21058-8 to withdraw bushing, making

sure Remover Adapter J-21474-2 is centered

and will clear hole in control arm.

d. Disassemble puller tools and position Installer

Adapter J-21474-2 on flanged end of new bushing.

Position Puller Screw J-21058-15 through in-

staller adapter and bushing; then place assembly

through hole in control arm.

NOTE:
Bushings are installed in one direction

only - flanged end of bushing seats against rolled

cutout side of control arm.

e. Install Receiver J-21474-5, Thrust Bearing, and

stalled view of tools.

f. Turn Iftit J-21058-8 to pull bushing into control

arm. Check position of bushing when installing

to make sure bushing is properly aligned. Seat

flanged end of bushing firmly against control

arm, but do not apply unnecessary force after

bushing is seated - to do so will distort control

arm.

WHEEL SPINDLE AND SUPPORT (Fig. 46)

Removal

Hemdve wheel drive spindle as outlined previously in

this section under "Wheel Bearing Adjustment".

Repairs

Out of 3/8" square steel bar stock, make bearing

removers and use as shown in Figure 47.

After removing deflector, spindle inner grease seal

and inner bearing race, bearing cups may be re-

moved while spindle support is still mounted to the

torque arm, by inserting remover tool and tapping

cup out. New bearing cups are installed using Tool

J-7817 cup installer and handle J-8092 (fig. 48).

To remove spindle support from torque arm, pro-

ceed as follows.

a. Disconnect parking brake cable from actuating

lever.

b.
Remove four nuts securing support to torque arm

and withdraw brake backing plate and position it

out of the way.

c. Disconnect shock absorber lower eye from strut

rod mounting shaft. It may be necessary to sup-

port spring outer end before disconnecting shock
absorber, as shock absorber has internal rebound

control.

d. Remove cotter pin and nut from strut rod mount-

ing shaft, then pull shaft from support and strut

rod.

e. Spindle support may then be removed and bearing

cups serviced as in Step 2 above.

4.
To remove drive spindle outer bearing and seal

proceed as follows.

a. Position Tool J-8331 between chamfered edge of

bearing seat and inner race of bearing (fig. 49).

Clamp Tool J-8331 in a vise and apply pressure

to unseat bearing.

CAUTION: Use extreme caution when position-

ing Tool J-8331 against machined surface of

spindle. Make sure all tool imperfections such

as nicks and burrs are removed from spindle

contact area before applying pressure to unseat

bearing.

b.
Position Tool J-8331 and spindle in an arbor

press and press bearing from spindle (fig. 50).

c. Remove outer seal and inspect for damage--re-

place if necessary. Outer seal must be placed on

spindle before outer bearing inner race and roller
