QuestionOn my 97 Merc Cougar, I may have a cv joint going out on the rear drivers side. What is involved in changing out this part? Will the ABS system play a major role in this swap?
Answer CAUTION: Do not begin this procedure unless the following parts are available:
new rear axle wheel hub retainer (4B477) (Step 1)
new driveshaft bearing retainer circlip (3Z498)
new inboard cv joint stub shaft pilot bearing housing seal (4B416)
Once removed, these parts must not be reused during assembly. Their torque holding ability or retention capability is diminished during removal.
Remove wheel covers (1130) and remove rear axle wheel hub retainers using a 36 mm socket. Loosen lug nuts (1012).
CAUTION: A frame contact hoist must be used to avoid damage to the halfshafts or rear axle shaft outer boot (4A331)/rear axle shaft inner boot (4L537).
Raise vehicle on a frame contact hoist.
Remove lug nuts and remove rear wheel and tire assemblies.
CAUTION: Rear brake anti-lock sensors (2C190) must be removed before halfshaft removal to prevent damage to the rear brake anti-lock sensors.
Remove retaining bolt and rear brake anti-lock sensors.
Using needle nose pliers, slide parking brake cable adjuster (2B599) downward until parking brake rear cable and conduit (2A635) is free.
Remove parking brake rear cable and conduit from rear disc brake caliper (2552).
Remove upper and lower disc brake caliper locating pins (2B296).
Remove rear disc brake caliper from rear disc brake rotor (2C026). Refer to Section 06-04.
WARNING: EXTREME CARE MUST BE TAKEN NOT TO STRETCH, TWIST OR KINK REAR BRAKE HOSE (2282).
Carefully wire rear disc brake caliper to brake line junction bracket as shown.
Remove brake rotor pushnuts and remove rear disc brake rotor.
Remove upper rear suspension arm and bushing bolt and nuts.
Wire rear suspension arm and bushing (5500) to shock absorber (18080) so it does not interfere with or damage rear axle cv joint boots (4697) when halfshaft is removed.
CAUTION: Failure to mark this position will result in bushing wind-up on assembly and incorrect ride height, causing misalignment and premature tire wear.
NOTE: When rear suspension arm and bushing bolt is removed from the rear wheel knuckle (5A969), the lower bushings will return to their relaxed positions.
Using a paint marker, mark the position of the rear suspension arm and bushing in relation to the rear wheel knuckle with the lower bushings in their relaxed position.
NOTE: Metric adapters (12 mm) make sure the adapters are fully threaded onto the hub studs and are positioned opposite the other adapter.
Attach Front Hub Remover/Replacer T81P-1104-C, Metric Hub Remover Adapters M12 x 1.5 T83P-1104-BH and Two Stud Adapter T86P-1104-A1 to hub studs as shown. With wrench, turn nut counterclockwise while holding wrench on threaded rod stationary until halfshaft is free in rear hub (1109).
Remove rear suspension arm and bushing retaining bolts.
Remove rear wheel knuckle while supporting outboard CV joint and rear axle cv joint boot. Carefully rest halfshaft on rear suspension arm and bushing.
CAUTION: Extreme care must be taken to prevent damage to the inboard cv joint stub shaft pilot bearing housing seal, rear axle housing (4010), rear brake anti-lock sensor indicator (2C189) or CV joint and rear axle cv joint boot.
Insert CV Joint Remover T89P-3514-A between rear axle housing and inboard cv joint stub shaft pilot bearing housing (4B413) and push tool outboard until inboard cv joint stub shaft pilot bearing housing becomes free from differential side gear (4236).
Remove halfshaft assembly from vehicle.
Insert Differential Plug T89P-4850-B into rear axle housing to prevent loss of lubricant.
Installation
Remove Differential Plug T89P-4850-B.
Replace inboard cv joint stub shaft pilot bearing housing seal. Refer to Section 05-02A (7.5 Inch Ring Gear) or Section 05-02B (8.8 Inch Ring Gear) for procedure.
NOTE: To install driveshaft bearing retainer circlip properly, start ends in groove and push driveshaft bearing retainer circlip into groove. This will prevent overexpanding of the driveshaft bearing retainer circlip.
Install a new driveshaft bearing retainer circlip on inboard cv joint stub shaft pilot bearing housing.
Lightly lubricate stub shaft splines with Constant Velocity Joint Grease (High Temp) E43Z-19590-A or equivalent meeting Ford specification ESP-M1C207-A.
Carefully align splines of inboard cv joint stub shaft pilot bearing housing with splines in differential side gear.
NOTE: A non-metallic mallet may be used to aid in seating driveshaft bearing retainer circlip into differential side gear groove. If a mallet is necessary, tap only on the outboard CV joint stub shaft until circlip engages.
Push halfshaft into differential side gear until driveshaft bearing retainer circlip engages with groove in differential side gear. Use care to prevent damage to inboard cv joint stub shaft pilot bearing housing seal.
Engage hub splines with outboard CV joint splines.
Install lower rear suspension arm bolts to rear wheel knuckle. Using inboard wrench as a lever, align paint mark on rear suspension arm and bushing with mark on rear wheel knuckle/bushing and tighten bolts to 160-200 Nm (118-147 lb-ft).
Install a new rear axle wheel hub retainer and pull CV joint into rear hub as far as possible by hand.
Install rear suspension arm and bushing-to-rear wheel knuckle retaining bolt and nut. Tighten bolt to 160-200 Nm (118-147 lb-ft).
Install rear disc brake rotor. Install new rotor pushnuts.
Install the rear disc brake caliper to the rear disc brake rotor with the outer brake shoe against the braking surface of the rear disc brake rotors. This prevents pinching the piston boot between the inner brake shoe and the piston. Refer to Section 06-04.
Install disc brake caliper locating pin and tighten to 108-135 Nm (80-99 lb-ft).
Install parking brake rear cable and conduit to rear disc brake caliper (2553).
Install parking brake cable adjuster. Refer to Section 06-05.
Install rear brake anti-lock sensors. Tighten retaining bolts to 19-27 Nm (14-20 lb-ft).
Check axle lube level and fill as necessary.
Check driveshaft bearing retainer circlip engagement by attempting to pull inboard cv joint stub shaft pilot bearing housing from axle. If driveshaft bearing retainer circlip is not seated, push CV joint in until driveshaft bearing retainer circlip is fully engaged in differential side gear.
Install wheel and tire assembly. Tighten lug nuts to 115-142 Nm (85-104 lb-ft).
Lower vehicle.
Tighten rear axle wheel hub retainer to 340 Nm (250 lb-ft).
this is the best i can dooo its not an easy job
