Front Steering Knuckle - Installation







INSTALLATION

1. If hub and bearing needs to be installed in knuckle, place hub and bearing squarely into center hole of knuckle with wheel speed sensor positioned toward trailing end of knuckle. Align threaded mounting holes of hub and bearing with mounting holes in steering knuckle, then install four mounting bolts. Progressively tighten mounting bolts in a crisscross pattern. Tighten mounting bolts to 65 Nm (45 ft. lbs.).

CAUTION: Before installing knuckle on ball joint stud, wipe ball joint stud and knuckle contact area free of any grease or debris, otherwise damage to knuckle can occur. Use a clean shop cloth with Mopar(R) Brake Parts Cleaner applied to it for proper cleaning. Do not spray stud directly.





2. Place knuckle (1) on ball joint stud (2).
3. Install a NEW steering knuckle to ball joint stud nut. Tighten nut by holding ball joint stud (2) with hex wrench while turning nut with a wrench. Using a crowfoot wrench on a torque wrench, tighten nut to 81 Nm (60 ft. lbs.) plus an additional 90° turn after torque is met.
4. Slide halfshaft stub shaft into hub and bearing assembly.

CAUTION: The strut clevis-to-knuckle bolts are serrated and must not be turned during installation. Install the nuts while holding the bolts stationary in the steering knuckle. Refer to the following steps.

CAUTION: If vehicle being serviced is equipped with eccentric cam strut attaching bolts, eccentric cam bolt must be installed in bottom (slotted) hole on strut clevis bracket.

NOTE: The strut clevis-to-knuckle bolts are installed differently on each side. Left hand side bolts are to be installed from vehicle rear to front. Right side bolts are to be installed from vehicle front to rear.





5. If servicing left knuckle:
a. Position the lower end of the strut assembly (1) in line with the upper end of the knuckle, aligning the mounting holes. Install the two strut clevis-to-knuckle bolts (2).
b. Install strut clevis-to-knuckle nuts (3) on the two bolts (2). While holding the bolts in place, tighten the strut clevis-to-knuckle nuts to 88 Nm (65 ft. lbs.) plus an additional 90° turn after torque is met.




6. If servicing right knuckle:
a. Position the lower end of the strut assembly (1) in line with the upper end of the knuckle, aligning the mounting holes. Install the two strut clevis-to-knuckle bolts (2).
b. Install strut clevis-to-knuckle nuts (3) on the two bolts (2). While holding the bolts in place, tighten the strut clevis-to-knuckle nuts to 88 Nm (65 ft. lbs.) plus an additional 90° turn after torque is met.

CAUTION: Before installing tie rod stud in knuckle steering arm, wipe stud and knuckle contact area free of any grease or debris, otherwise damage to knuckle can occur. Use a clean shop cloth with Mopar(R) Brake Parts Cleaner applied to it for proper cleaning. Do not spray stud directly.





7. Install outer tie rod (4) stud into knuckle (1) steering arm. Start nut (5) onto tie rod stud. While holding stud stationary, tighten nut using a wrench. Using a crowfoot wrench on a torque wrench, tighten nut to 47 Nm (35 ft. lbs.) plus an additional 180° turn after torque is met.




8. Place wheel speed sensor cable grommet in clip (3) at knuckle. Close clip.




9. Attach wheel speed sensor routing bracket (3) to strut assembly (1). Install and tighten screw (2) to 13 Nm (115 in. lbs.).




10. Clip wheel speed sensor connector (2) and routing clip (3) to frame rail outer reinforcement.
11. Connect vehicle wiring harness (1) to wheel speed sensor connector (2).
12. Install brake rotor, then install disc brake caliper and adapter assembly. Brake Rotor - Installation
13. Verify that wheel speed sensor is not routed improperly allowing cable to come in contact with brake rotor or other moving parts.




14. Install washer (6) and hub nut (3) on end of halfshaft stub shaft (5). With aid of a helper applying brakes to keep front hub from turning, tighten hub nut to 244 Nm (180 ft. lbs.).
15. Install spring washer (2) and hub nut lock (7) over hub nut and stub shaft. Install a NEW cotter pin (1) securing nut lock in place and tightly wrap cotter pin prongs around nut lock.




16. Install tire and wheel assembly (1) Tires and Wheels - Installation. Install and tighten wheel mounting nuts (3) to 135 Nm (100 ft. lbs.).
