tool and compress spring until screw is bottomed

out.

NOTE: Spring coil ends must be against spring

stops in upper and lower seats.

2.
Lift spring and tool assembly into place and position

so that the upper spring stop is inboard.

NOTE: Locating tab on upper spring seat may

be flattened before reinstalling spring.

3.

sorber—Installation in this section.

Corvette

Removal

1.
With car on suitable hoist or jack, (support vehicle

by frame so control arms may swing free) remove

wheel and tire assembly, stabilizer bar and shock

absorber. Loosen the lower ball joint to steering

knuckle nut, and the' two lower control arm cross

shaft bushing bolts.

2.
Place Tool J-6874-1 across top of sixth coil (ap-

prox.),
then loosely secure Tool J-6874-2 to the up-

per shoe, with attaching capscrews and lock washers.

The upper shoe "V" notch and lower shoe raised land

should contact spring.

3.
Insert Tool J-6874 up through center of spring and

attach to upper and lower shoe assembly.

4.
Position spacers under shock absorber mounting hole

and against bottom of lower control arm. Install

special bearing washer and Tool J-6874-5. Locate

bearing against spacer and large washer against

bearing. Feed screw up through large washer bear-

ing and spacer and thread into Tool J-6874 and

tighten snugly (fig. 22).

5.
Center shoe assembly on spring and tighten screw

until a very slight compression is placed on spring

(fig. '22). Then firmly tighten down the two cap-

screws securing the upper and lower shoes to lock

these shoes to spring.

6. Turn head of screw until spring is compressed just

enough to clear the spring tower, then remove the

lower ball joint to steering knuckle nut (fig. 22).
NOTE: It may be necessary to assist the

spring out of the spring tower with a pry bar or

a similar tool.

7.
Disconnect the lower ball joint from the steering

knuckle and lower the control arm with the com-

pressed spring. Immediately release compression

on spring by backing off long screw. Release spring

and tool and withdraw spring.

CAUTION: The spring force under compres-

sion is very large. Exercise every safety pre-

caution when performing this operation to see

that individuals and materials subject to damage

are removed from the path of the spring when

the control arm is being lowered. Also, the

compressed spring
be relaxed immedi-

ately after lowering the control arm to reduce

the time of exposure to the large compressive

force.

Installation

1.
Position spring with closely coiled end up. Place

Tool J-6874-1 across the top of the sixth coil (ap-

prox.) then loosely secure Tool J-6874-2 to the

upper shoe with attaching capscrews and lock wash-

ers.
The upper shoe MV" notch and lower shoe

raised land should contact spring.

2.
Insert Tool J-6874 up through center of spring and

attach to upper and lower shoe assembly with bolt

and nut.

3.
Set spring in its seat on the lower control arm.

4.
Position spacers centrally under shock absorber

mounting hole and against bottom of lower control

arm. Install bearing, large washer and Tool

J-6874-5.
Locate bearing against spacer and large

washer against bearing. Feed the screw up through

large washer, bearing and spacer and thread into

yoke rod. Tighten snugly, but do not start to draw

down yet

5.
Center the shoe assembly on the spring and tighten

the lag screw until a very slight compression is

placed on spring, then firmly tighten down the two

capscrews securing the upper and lower shoes. This

will lock the shoes to the coil spring.

6. Turn head of screw until spring is compressed just

enough to clear the spring tower.

NOTE: It may be necessary to assist the

spring into the spring tower with a pry bar or

similar tool.

7.
Immediately install the lower ball joint into steering

knuckle and secure in place with attaching nut.

8. Release compression on spring and at the same time

use a drift to guide the coil spring into its proper

seat. End of coils must be 3/8" from coil stops in

spring seat.

9. Tighten the lower ball joint to steering knuckle nut

and lock with cotter key.

10.
Install shock absorber and stabilizer bar.

11.
Install wheel, tire and drum assembly.

12.
Remove car from hoist or jack stands.

13.
Tighten the two lower control cross shaft bushing

bolts to 45-55 lbs. ft. torque.

NOTE: If a suitable adjustable jack-stand is

RIDING HEIGHT CHECK

(Chevrolet, Chevelle Camaro and Chevy II)

In case of vehicle riding height complaints, a spring

height check will show if the rear suspension is at the

right height.

1.
Position car on smooth level floor.

2.
Vehicle must be at curb weight (full gas tank, no

passengers, spare and jack in trunk). Car should be

raised up a few times to allow suspension to settle

with car weight to eliminate friction at arm pivots.

3.
On Chevrolet and Chevelle models, measure riding

height as the distance from the top of the axle hous-

ing to frame kick-up (fig. 6).

4.
On Chevy II models, measure riding height as the

distance from lower surface of bumper support

bracket to top of axle housing (fig. 7).

5.
On Camaro models measure riding height as the

distance from jounce bumper upper attaching bolt to

top of axle housing (fig. 8).

6. Riding heights vary between models* Refer to speci-

fications section for vehicle and model application.

WHEEL ALIGNMENT (CORVETTE)

Camber

Wheel camber angle is obtained by adjusting the eccen-

tric cam and bolt assembly located at the inboard mount-

ing of the strut rod (fig. 9). Place rear wheels on

alignment machine and determine camber angle. To

adjust, loosen cam bolt nut and rotate cam and bolt as-

sembly until specified camber is reached. Tighten nut

securely and torque to specifications.

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-
