Drive Train
DRIVELBNE
The Stingray driveline consists of the drive-
shaft, differential carrier, and axle drive-
shafts. The driveshaft is of conventional tu-
bular design with a universal joint at each end.
The differential is mounted directly to a sus-
pension crossmember. Power is transmitted
to the wheels through universal-joined axle
driveshafts. The 1984 Corvette uses two types
of drive shafts, one made from aluminum and
the other from steel. Each shaft is installed in
the conventional manner.

REMOVAL AND INSTALLATION
NOTE: Follow steps 1, 5, 6, 7, and 8 to
remove the driveshaft from 1980 and later
Corvettes. During installation, torque the
bearing strap fasteners to 15ft. Ibs.
1. Jack the car to a convenient working
height and support with jackstands.
2. Wedge a block of wood between the
top of the differential carrier and the car floor
to keep the carrier from twisting on its rub
ber mounts when the front support bracket is
disconnected.
3. Loosen and remove the carrier sup
port-bracket front bolt. Remove the two rub
ber biscuits and large washer. Discard and
replace the rubber biscuits if they show any
deterioration.
4. Remove the two side bolts or front
thru-bolt on later models from the carrier
support bracket. Loosen, but do not remove,
the rear thru-bolt and swivel the bracket down
and away.
5. Mark the driveshaft so that it may be
reinstalled in its original position. Remove the
U-bolts from both ends of the driveshaft.
6. Push the front yoke into the transmis-

sion and remove the driveshaft by pulling it
down and to the rear.
7. Check the universal joints and replace
damaged or worn units. Grease both univer
sal joints before reinstalling them.
8. Install the driveshaft and attach to the
transmission yoke and carrier flange.
9. Install the front bolt biscuits and flat
washer and raise the bracket to the cross-
member.
NOTE: At this point it may be necessary to
install a jack under the carrier. This witt
aid in lining up the side-bracket bolt holes
and compressing the rubber biscuits. 10.
Install the front crossmember bolt and nut.
Install the side bolts. Front bolt torque is 30
ft. Ibs. Torque the two side bolts to 45-55
and the long thru-bolt to 40-60 ft. Ibs.
NOTE: The carrier support bracket bolts
frequently work loose, causing vibration
and rear axle hop. Periodic torquing of these
four bolts will eliminate this problem.
UNIVERSAL JOINT OVERHAUL
Except for early Stingrays, Corvettes are
equipped with lubed-fbr-Iife universal joints
without grease fittings. Whenever universal
