SERVICE PROCEDURES

Procedures for the removal and installation of the driveshafts are essentially the same for all front wheel drive vehicles. Each driveshaft has a spring within the inboard Tripod C/V joint that maintains constant engagement with the transaxle. This allows the drive shaft to be removed without dismantling part of the transaxle.

CAUTION: Boot sealing is vital to retain special lubricants and to prevent foreign contaminants from entering the C/V joint. Mishandling, such as allowing the assemblies to dangle unsupported, pulling or pushing the ends can cut boots or damage C/V joints. During removal and installation procedures always support both ends of the driveshaft to prevent damage.

DRIVESHAFTS, REMOVE INSTALL

HUB NUT REMOVAL

Hub nut removal and installation is the same for all front wheel drive vehicles. For installation see Hub

Nut Assemblies Install.

(1) Remove cotter pin, lock and spring washer (Fig.

3).

Fig. 3 Remove Cotter Pin, Nut Lock, & Spring

Washer

(2)Loosen hub nut and wheel nuts while vehicle is on floor and brakes applied (Fig. 4).

(3)Raise vehicle, see Hoisting in Lubrication and Maintenance, Group 0 of this service manual.

(4)Remove hub nut, washer, wheel and tire assembly (Fig. 5).

DRIVESHAFT ASSEMBLIES REMOVE

Inboard C/V joints have stub shafts splined into the differential side gears, or splined into the intermediate shaft on the right side of an equal length system.

SUSPENSION/DRIVESHAFTS 2 - 27

Fig. 4 Loosen Hub Nut & Wheel Nuts

Fig. 5 Remove Hub Nut & Washer Loosen Shaft

Driveshafts are retained in the side gears by a constant spring force provided by a spring contained within the inboard C/V joints.

(1)For removal of right driveshaft, the speedometer pinion must be removed BEFORE shaft removal (Fig. 6).

(2)Remove clamp bolt securing ball joint stud into steering knuckle (Fig. 7).

(3)Separate ball joint stud from steering knuckle by prying against knuckle leg and control arm (Fig. 8).

CAUTION: Do not damage ball joint or C/V joint boots (Fig. 8).

(4) Separate outer C/V joint splined shaft from hub by holding C/V housing while moving knuckle(hub) assembly away (Fig. 9).

CAUTION: Do not pry on or otherwise damage wear sleeve on outer C/V joint.

Fig. 6 Remove Speedometer Pinion Clamp (For

Right Driveshaft).

Fig. 7 Remove Ball Joint to Steering Knuckle Clamp Bolt

(5) Support assembly at C/V joint housings. Remove by pulling outward on the inner joint housing.

DO NOT PULL ON SHAFT (Figs. 10 and 11).

The driveshaft, when installed, acts as a bolt and secures the hub/bearing assembly. If the vehicle is to be supported or moved on its wheels, install a bolt through the hub to ensure that the hub bearing assembly cannot loosen.

Length

(1) Hold inner joint assembly at housing (Figs. 11 and 12) while aligning and guiding the inner joint spline into the transaxle or intermediate shaft assembly. On Equal Length System vehicles only, be sure that the rubber washer seal is in place on the right inner C/V joint (Fig. 1).

Fig. 12 Installing Inner Shaft into Transaxle

CAUTION: Seal/Wear Sleeve Lubrication During any service procedures where knuckle and driveshaft are separated. Thoroughly clean seal and wear sleeve with suitable solvent (solvent must not touch boot) and lubricate both components prior to installing driveshaft. Lubricate wear sleeve and seal with Mopar Multi-Purpose Lubricant, or equivalent.

Apply on the full circumference of the Wear Sleeve a bead of lubricant that is 6 mm (1/4 in.) wide to seal contact area (Fig. 13). Fill the seal lip to housing cavity on bearing seal with lubricant. Lubricant is to be applied around complete circumference of the seal, and seal lip should be wet with lubricant (Fig. 13). Use Mopar Multi-Purpose Lubricant or equivalent for lubrication of the Wear Sleeve and Bearing Seal.

(2) Push knuckle (hub) assembly out and install splined outer C/V joint shaft in hub (Fig. 14).

CAUTION: Steering knuckle clamp bolt shown in (Figs. 14 and 15) is Prevailing Torque Type, original

or equivalent bolt must be installed during assembly.

Fig. 14 Install Outer Shaft into Hub

(3)Install knuckle assembly on ball joint stud (Fig.

15).

(4)Install and tighten clamp bolt to 95 NIm (70 ft. lbs.) torque (Fig. 16).

(5)Install speedometer pinion (Fig. 17).

(6)Fill differential with proper lubricant (see Lubrication and Maintenance Group 0).

(7)Install hub nut assembly.

(8)If after installing the driveshaft assembly, the inboard boot appears collapsed or deformed. Vent the inner boot by inserting, a round tipped small diameter rod between the boot and shaft. If necessary, massage the boot to remove all puckers being careful not to allow dirt to enter or grease to leave the boot cavity. The clamp must be removed and discarded be-

fore the rod can be inserted. After venting, install a new Service Clamp. (See Boots Install section at the end of this group for details).

HUB NUT INSTALL

The front wheel hub nuts use a lock and cotter pin to maintain proper wheel bearing preload and prevent the nut from backing off. Install the assembly as follows:

(1)Install washer and hub nut after cleaning foreign matter from threads (Fig. 18).

(2)With brakes applied, tighten hub nut to 245 NIm (180 ft. lbs.) torque (Fig. 19).

(3)Install lock, spring washer and new cotter

pin. Wrap cotter pin prongs tightly around nut lock (Fig. 20).

Fig. 20 Install Spring Washer, Nut Lock, & New Cotter Pin

(4) Install wheel and tire assembly. Tighten wheel nuts to 129 NIm (95 ft. lbs.) torque (Figs. 21).

DRIVESHAFT RECONDITIONING PROCEDURE

Driveshaft reconditioning and/or boot replacement for all front wheel drive vehicles is essentially the same per C/V joint.

Note: that lubricant requirements and quantities are different for Inner Joints than for Outer Joints, and type being serviced. Use only the recommended lubricants.

See (Fig. 1) for the exploded view of the front drive shaft components and there location in the assembly.

Fig. 21 Install Wheel And Tire Assembly

Driveshaft requirements are different for various vehicle models, engines, and transaxles, and often change from one model year to the next.

Driveshaft parts will be different to accommodate this. Therefore, when replacing parts, be sure to use only those specified in the service parts catalog. For the exact model year, model, engine, transaxle, and type being serviced.

Fig. 2 Separate Tripod From Housing S.S.G.

G.K.N. The retention system on this assembly is a integral part of the plastic collar on the inside of the C/V joint housing. Clamp the stub shaft of the C/V joint housing in a vise, use protective caps on jaws of vise to prevent damage to stub shaft. Hold the interconnecting shaft on an angle, while gently pulling on the shaft until one of the tripod bearings is free of the retaining collar. Continue holding the interconnecting shaft on an angle and gently pull on the shaft until all rollers are free of the retaining collar. See (Fig. 3).
