NOTE:
If the axle shaft assembly is removed, check runout of the shaft itself. The forged (unmachined)
part of the shaft is allowed to have as much as 3.0 mm (0.120 inch) runout. This alone will not cause a
vibration condition.
1. Position the special tool on the wheel hub or axle flange face, as close to the outer edge as possible. Zero the indicator to allow the pointer to deflect either way.
2. Rotate the hub or flange one full turn and note the maximum and minimum readings. The difference between the maximum and minimum readings will be the total face runout. The
runout must not exceed 0.127 mm (0.005 inch).
Drive Pinion Stem and Pinion Flange
Check the pinion flange runout when all other checks have failed to show the cause of vibration.
One cause of excessive pinion flange runout is incorrect installation of the axle drive pinion seal.
Check to see if the spring on the seal lip has been dislodged before installing the ring gear and pinion.
Axle Noise
NOTE: Before disassembling the axle to diagnose and correct gear noise, eliminate the tires, exhaust,
trim items, roof racks, axle shafts and wheel bearings as possible causes. Follow the diagnostic
procedures in Section 100 - 04 .
The noises described as follows usually have specific causes that can be diagnosed by observation as
the unit is disassembled. The initial clues are the type of noise heard during the road test.
Gear Howl and Whine
Howling or whining of the ring gear and pinion is due to an incorrect gear pattern, gear damage or
incorrect bearing preload.
Bearing Whine
Bearing whine is a high- pitched sound similar to a whistle. It is usually caused by worn/damaged
pinion bearings, which are operating at driveshaft speed. Bearing noise occurs at all driving speeds.
This distinguishes it from gear whine which usually comes and goes as speed changes.
As noted, pinion bearings make a high- pitched, whistling noise, usually at all speeds. If however there
is only one pinion bearing that is worn/damaged, the noise may vary in different driving phases. If
pinion bearings are scored or damaged or there is a specific pinion bearing noise, new pinion bearings
must be installed. A worn/damaged bearing will normally be obvious at disassembly. Examine the
large end of the rollers for wear. If the pinion bearings original blend radius has worn to a sharp edge, a new pinion bearing must be installed. Klj . 6 ba

z
Do not drop assembled halfshafts. The impact will cut the boots from the inside without
evidence of external damage.
z Inspect all machined surfaces and splines for damage.
Wheel and Tire Balancing, Rear
WARNING: Do not balance the rear wheels and tires while mounted on the vehicle.
Possible tire disintegration, differential or halfshaft failure can result, causing personal injury
or extensive component damage. Use an off- vehicle wheel and tire balancer only.
Hoisting
CAUTION: Use a frame- contact hoist only. Vehicle or component damage can result if
other types of hoists are used.
Never raise the vehicle using the halfshafts as lift points.
Undercoating and Rustproofing
During undercoating and rustproofing procedures, protect the boots from the coating materials.
Foreign materials on the rubber boots will cause extreme advanced wear. Klj . 3 ba

Brake Pressure Control Valve
The brake pressure control valve proportions the pressure to the rear brakes.
zWhen the brake pedal is applied, brake fluid pressure passes through the proportioning valves
to the rear brake system until the valve split point is reached.
z Above its split point, the proportioning valve begins to reduce the hydraulic pressure to the rear
brakes, creating a balanced braking condition between the front and rear brakes.
Brake Tubes and Hoses CAUTION: Never use copper tubing. It is subject to fatigue, cracking and corrosion which
could result in brake tube failure.
Steel tubing is used throughout the brake hydraulic system. All brake tube fittings must be correctly
double flared to provide strong leakproof connections. When bending the tubing to fit the underbody or
rear axle contours, be careful not to kink or crack the tube.
If a section of brake tube is damaged, the entire section must be removed and a new tube of the same
type, size, shape and length installed.
When replacing hydraulic brake tubing, hoses, or connectors, tighten all connections securely. After
installation, bleed the brake system. For additional information, refer to Section 206 - 00 . Klj . 3 ba
