5.
Remove shim and bearing spacer from spindle

support.

6. Note size of shim used. If dial indicator reading

was more than
.008",
select a shim thinner by the

amount needed to bring end play within limits. If

dial indicator reading was less than
.001",
select a

shim thicker by the amount needed to bring end play

within limits.

NOTE: Shims are available in thicknesses from

.097"
to .148" in increments of
.003".

EXAMPLE: Bearing end play reading obtained

on dial indicator was
.011",
.003" over limit.

Bearing shim removed from spindle measures

.145".
New shim installed measures .139", .006"

smaller. End play is now decreased by .006" and

is
.005",
which is within the .001" to .008" limit.

7.
After determining shim thickness, install bearing

spacer and shim on spindle. Position spindle in

spindle support.

8. Press inner bearing race and roller assembly on

spindle as follows.

a. Position Tool J-4731 over spindle and against

bearing inner race.

b.
Position washer and spindle nut on spindle and

proceed to tighten nut until bearing is forced on

spindle sufficiently to allow spindle drive flange

to be installed (fig. 13). Remove spindle nut,

washer and Tool

COIL SPRING

Chevrolet

Removal

To remove either or both rear coil springs proceed

as follows.

1.
Raise rear of vehicle and place jack stands under

frame. Support vehicle weight at rear, using either

a jack or post of twin-post hoist under axle.

2.
Remove both rear wheels from vehicle.

3.
With the car supported as in Step 1, so that the rear

springs are compressed by weight of vehicle; per-

form the following:

a. Disconnect both rear shock absorbers from the

anchor pin lower attachment.

b.
Loosen the upper control arm(s) rear pivot bolt

(do not remove the nut).

C. Loosen both the left and the right lower control

arm rear attachment (do not disconnect from axle

brackets).

d. Remove the rear suspension tie rod from the

stud on the axle tube.

4.
At the lower seat of both rear coil springs, slightly

loosen the nut on the bolt that retains the spring and

seat to the control arm. When the nut has been

backed off the maximum permissible, all threads of
the nut should still be engaged on the bolt.

CAUTION: Under ,no condition should the nut,

at this time, be removed from the bolt in the

seat of either spring.

5.
Slowly lower the support (jack or hoist post) that has

been in place under the rear axle, thereby allowing

the axle to swing down, carrying the springs out of

their upper seat and providing access for spring

removal.

6. Remove the lower seat attaching parts from each

spring, then remove the springs from the vehicle

(fig. 14).

Installation

1.
Position the springs in their upper seat so that end

of top coil is 3/8" ± 1/8" from end of stop. Install

the lower seat parts on the control arm, with the nut

finger tight on the spring retainer bolt.

NOTE: Omit the lock washer under the special

high carbon bolt, so that sufficient bolt thread

will be available to start the nut. The lock

washers will be installed later (in Step 4).

2.
By alternately raising the axle slightly and then

re-snugging the nut on each spring lower seat bolt,

move the axle upward until vehicle weight is fully

pressed to approximately curb height, positively

position the springs in the lower seats by torquing

the nut on the lower seat bolt (fig. 15).

Re-connect shock absorbers, torque rear attach-

ment of upper and lower control arms, and re-

connect the axle tie rod at proper torque.

With the rear of vehicle still supported by jack under

axle;
remove the nut from the lower seat bolt of one

bly to hang freely, and position supports under both

frame side rails.

2.
Support axle assembly with an adjustable lifting

device, and disconnect shock absorber at axle

bracket. Shock absorber on side opposite need not

be disconnected if only one spring is being removed.

Refer to Shock Absorber Removal procedures out-

lined in this section.

3.
Lower axle assembly until suspension reaches end

of travel; then pry lower% pigtail over vertical re-

tainer on axle bracket and remove spring and insula-

tor from vehicle.

Installation

1.
Position rubber insulator on end of spring, making

sure that end of pigtail is butted against stop in

insulator. Install insulator and spring in upper

spring seat so that insulator is properly indexed

against stop (fig. 16).

2.
Pry lower pigtail portion of spring over vertical

flange of the axle bracket spring seat.

3.
Raise axle to allow shock absorber installation.

Position shock absorber in axle bracket. Torque nut

as outlined in Shock Absorber Installation

procedures.

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

Install Spacer J-21474-1 between sides of control

arm and, over bushing so that spacer follows

contour of bushing. Refer to Figure 38 for in-

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.

2.
Replace the carrier mounted, upper control arm rear

bushing using the following procedure.
