Full general INFORMATION  (back to CONTENTS)

CAUTION: Anytime rear beam servicing is necessary, or axle. is being rotated through use of the engine or other means, Drag BOTH REAR WHEELS.

The Sure-Grip differential is being offered as a special equipment option in 8-1/4 in. rear axles (Figs. 1 and two).

The Sure-Grip differential design is basic and uncomplicated and consists of a ii piece case structure and is completely interchangeable with the conventional differential and as well the previous
type.

A conventional differential allows the driving wheels to rotate at dissimilar speeds while dividing the driving torque as between them. This part is ordinarily desirable and satisfactory. Nevertheless, the total driving torque can be no more than double the torque at the lower traction bicycle. When traction conditions are not the same for both driving wheels, a portion of the available traction cannot exist used.

The Sure-Grip differential allows the driving wheel with the better traction condition to develop more driving torque than the other wheel, then that the total driving torque can be significantly greater than with a conventional differential.

Sure-Grip is not a locking differential. In normal driving atmospheric condition the controlled internal friction is easily overcome during cornering and turning so that the driving wheels can plow at unlike speeds. Extreme differences in traction conditions at the driving wheels may permit i wheel to spin.

Certain-Grip has been engineered to perform its specialized functions with minimum effect on normal vehicle operations.

The cone clutch Certain-Grip differentials are similar to respective conventional differentials except for the incorporation of the helix-grooved cones that clutch the side gears to the differential case. The grooves clinch maximum lubrication of the clutch surface during operation. The cones and side gears are statically leap preloaded to provide an internal resistance to differential action within the differential case itself. This internal resistance provides pulling ability while under extremely low tractive conditions such as mud, snow or ice when encountered at one of the rear wheels.
During torque application to the axle, the initial jump loading of the cones is supplemented by the gear separating forces between the side gears and differential pinions which progressively increases the friction in the differential. It should be remembered that this differential is non a positive locking type and will release before excessive driving force can exist practical to one wheel.

Sure-GRIP DIFFERENTIAL IDENTIFICATION  (back to CONTENTS)

Identification of Sure-Grip differential assembly can hands be made past lifting both rear wheels off the ground and turning them. If both rear wheels turn in the same direction simultaneously, the vehicle is equipped with a Sure-Grip Differential. Another means of identification is past removing the filler plug and using a flashlight to look through the filler plug hole to identify the type of differential example.

SERVICE PROCEDURES  (back to CONTENTS)

Sure-GRIP DIFFERENTIAL Dissonance  (dorsum to CONTENTS)

(Chatter-Moan)
Dissonance complaints related to rear axles equipped with cone-clutch Sure-Grip should be checked to decide the source of the racket. If a vehicle ride bank check produces the noise in turns but non direct ahead, the probable crusade is wrong or dissipated rear axle lubricant. The following draining and flushing procedure has been established for the Certain-Grip Differential before it is removed from the vehicle and replaced.

Circumspection: When servicing vehicles equipped with Sure-Grip differentials do non use the engine to rotate axle components unless both rear wheels are off the footing. Sure-Grip equipped axles can exert a significant driving strength if one bike is in contact with floor and could cause the vehicle to motility.

(1) With lubricant of rear axle associates at operating temperature raise machine on hoist then rear wheels are free to plow. Install jack stands.
(2) Remove axle encompass and drain and discard lubricant. Rotate differential so hole in case is facing down. Wipe out all accessible areas of carrier. The purpose of draining and discarding this lubricant is to rid the axle of whatsoever solid particles or liquid contaminants that may be contributing to the dissonance status.
(3) Scrape any gasket fabric from housing cover and thoroughly clean surface with mineral spirits or equivalent and dry completely. Apply a i/sixteen inch to three/32 inch bead of MOPAR Silicone Condom Sealant, Office No. 4318025 or equivalent (See Figure vii in Conventional Axle Section of this Group) along the commodities circumvolve of the cover.
Allow sealant to cure while cleaning carrier gasket flange with mineral spirits or equivalent. Dry out surface completely. Install cover on axle and torque cover screws to 35 ft. lbs. (47 N�thou). Below one of the cover screws, install the ratio identification tag.
If for any reason cover is non installed within 20 minutes subsequently applying sealant, quondam sealant should be removed and a new dewdrop installed.
(4) Remove jack stands. Enhance or lower hoist until vehicle is in a level position.
(5) Remove filler plug. Install iv ounces (.1183 litres) of MOPAR Hypoid Gear Oil Additive Friction Modifier, Office No. 4318060 or equivalent in the axle. Refill axle to proper level with MOPAR Hypoid Lubricant, Office No. 4318058 or equivalent.
(6) Install filler plug. Lower vehicle.

TESTING SURE-GRIP DIFFERENTIAL  (back to CONTENTS)

The Sure-Grip differential can be checked to decide if its performance is satisfactory without removing the differential and carrier assembly from the vehicle.

(1) Position vehicle on a hoist with engine off and the transmission selector lever in park if automatic or in depression gear if transmission.
(2) Try to rotate wheel past applying turning force with hands gripping tire tread expanse.
(3) If y'all find information technology extremely difficult, if not impossible to manually turn either bicycle, you can consider the Sure-Grip differential to exist performing satisfactorily. If you find it relatively easy to continuously plow either wheel the differential is not performing properly and should be removed and replaced. The Certain-Grip Differential and internal parts are serviced as a complete associates but. Nether no circumstances should the differential be removed and disassembled and reinstalled.

CAUTION: During removal and installation of axle shafts, DO NOT rotate an beam shaft unless both are in position. Rotation of one axle shaft without the other in place may result in misalignment of the two spline segments with which the axle shaft spline engages, and will necessitate realignment procedures when shaft is installed.

Removal
Follow the aforementioned process outlined under conventional differential removal.

Cleaning and Inspection  (back to CONTENTS)
(1) Clean the Sure-Grip differential assembly in a fast evaporating mineral spirits or a dry cleaning solvent and with exception of bearings, dry with compressed air.
(2) Audit differential begetting cones, cups and rollers for pitting, spalling or other visible damage. If replacement is necessary, remove bearing cones from differential case using procedure outlined in conventional axle department of this group.
(3) Visually inspect differential case for cracks or other visible impairment which might return it unfit for further service.

Associates  (dorsum to CONTENTS)
(1) If during cleaning and inspection the differential bearings were institute to be unfit for further use and were removed follow process outlined in conventional axle section of this grouping.
(2) On axles requiring ring gear to exist installed on differential instance, salve the sharp edge of the chamfer on the inside diameter of the ring gear using an Arkansas rock (Fig. iii). This is very important, otherwise during the installation of ring gear on differential case, the abrupt edge will remove metal from the pilot diameter of example, which can get imbedded between differential case flange and gear; causing ring gear non to seat properly.
(3) Heat the band gear with a heat lamp or by immersing the gear in a hot fluid (h2o or oil). The temperature should non exceed 300 degrees Fahrenheit (149.0 degrees Celsius). DO Non Apply A TORCH. It is advantageous to use pilot studs equally spaced in three positions to align the gear to the case.
(4) Using new drive gear screws (left hand threads) insert through case flange and into bulldoze gear.
(5) Position unit between brass jaws of a vise and alternately tighten each screw to 70 ft. lbs. (95 Northward�1000) on all axles.
(6) Follow process outlined in conventional axle assembly for setting drive pinion depth of mesh, drive gear backlash aligning and bearing preload adjustment.

Installation  (back to CONTENTS)
Follow the same procedure outlined under conventional differential installation.

LUBRICATION  (back to CONTENTS)
Multi-Purpose Gear Lubricant, equally divers past the American Petroleum Found GL-v should exist used in all rear axles with conventional differentials; MOPAR Hypoid Lubricant, Part No. 4318058 is an oil of this type and is recommended or equivalent.

In Certain-Grip Differentials 4 ounces (.1183 litres) of MOPAR Hypoid Gear Oil Additive Friction Modifier, Part No. 4318060 equivalent must be included with this make full.

Fluid Level Check  (back to CONTENTS)
For normal passenger machine service, periodic fluid level checks are not required. At each engine oil change however, a fluid level cheque is recommended When this check is performed with the car in a level position, supported by the intermission, the fluid level should exist 1/4 inch (6.4 mm) beneath the filler plug opening.

When the fluid level check is made with the vehicle on a frame contact blazon hoist, with the axle hanging gratis, the fluid level should not be lower than the bottom of the filler plug opening.

Caution: Should the rear axle become submerged in h2o, the lubricant must exist inverse immediately to avoid the possibility of early axle failure resulting from contamination of the lubricant by water.
