height CHEVROLET DYNASTY 1993 Workshop Manual

CAUTION: See Figure 14 to determine side gear
thrust washer thickness. Side gear end play must be
within.001 to .013 inch.Four select thrust washes are available: .032, .037,
.042, and .047 inch.
Side gear thrust washers are available in 4
select thicknesses: .032, .037, .042, and .047 inch. Measure the depth from the differential case to the
machined surface in 3 places, as shown in Figure 13.
Then measure the height of raised stepon the ring
gear. The difference, minus the proper side gear end
play (.001 to .013 inch) is the proper thrust washer
thickness. For the other side gear: After assembling the differ-
ential side gears, pinion gears, and pinion gears with
the pinion gear washers but withoutthe side gear
thrust washers. Rotate the assembly two full revolu-
tions both clockwise and counterclockwise. Set up dial indicator as shown in Figure 14 and
record end play. Rotate side gear 90 degrees and record another end play. Again, rotate side gear 90
degrees and record a final end play.
Using the smallest end play recorded, shim that side
gear to within .001 to .013 inch.
CAUTION: After reassembly of the differential assem-
bly, insert the inner joint housing spline from a drive
shaft into the side gear. By hand, turn the side gear
with the joint housing spline. If the side gear will NOT
turn, or it feels very tight, remove the ring gear and
install a thinner side gear thrust washer.
Side gear thrust washers are available in four
select thicknesses: .032, .037, .042, and .047 inch.

GENERAL INFORMATION
All sunroofs are equipped with drain tubes that are
located in the A, B or C-pillars. The drain tubes
must be kept open to prevent water from entering
the passenger compartment.
LUBRICATION
(1) Lubricate cables with Lubriplate or equivalent
when cables are replaced. (2) Periodically clean dirt from guide rail covers.
DRAIN TUBES
² Inspect the drain holes, located in the trough
around the sunroof opening to verify they are clear.
Inspection should be performed at least once a year
or when problems are suspected. If drain hose or
tubes are plugged, use compressed air or blunt flexi-
ble wire to clear them. If tubes cannot be cleared,
they must be repaired.
² The lower ends of the rear drain tubes are located
in the rear quarter panel drop wells. To clear rear
drain tubes, use compressed air or blunt flexible wire
from the lower ends of the tubes.
