This procedure covers removal and installation of the rear wheel knuckle/spindle assembly on a 2005 Dodge Viper, including disconnecting suspension components, brake hardware, and wheel speed sensor.
Warnings
⚠️Vehicle must be securely supported on jack stands rated for the vehicle weight. Never work under a vehicle supported only by a floor jack.
⚠Do not allow brake caliper to hang by the brake hose. Suspend it with wire or a proper hanger to prevent hose damage.
⚠The ball joint taper fit can release suddenly when separating. Keep hands and body clear of the separation point.
ℹ️Mark the orientation of eccentric adjustment bolts if equipped before removal to preserve alignment settings.

Preparation
- Park vehicle on level surface and engage parking brake.
- Loosen rear wheel lug nuts while vehicle is on the ground.
- Raise rear of vehicle and support securely on jack stands at manufacturer-approved jacking points.
- Remove rear wheel and tire assembly.
- Apply penetrating oil to suspension fasteners and allow to soak if corrosion is present.
Procedure
- 1Remove brake caliperRemove the 2 brake caliper mounting bolts from the rear of the caliper bracket using a 15mm socket. Slide the caliper off the rotor and suspend it from the chassis using wire or a caliper hanger. Do not disconnect the brake hose or allow the caliper to hang by the hose.
- 2Remove brake rotorRemove the brake rotor from the wheel hub. If the rotor is stuck, thread two M8 bolts into the threaded holes on the rotor face and tighten evenly to press the rotor off the hub. The Viper uses a conventional cast-iron rotor that slides off the hub studs once the caliper is removed.
- 3Disconnect wheel speed sensorLocate the ABS wheel speed sensor on the rear of the knuckle. Disconnect the electrical connector by pressing the release tab. Remove the sensor retaining bolt (confirm socket size against the FSM) and carefully extract the sensor from its bore. Note the condition of the O-ring for replacement.
- 4Disconnect sway bar end linkVERIFY AGAINST FSM: The rear sway bar end link typically connects to the lower control arm on this platform. Hold the ball stud with an Allen key to prevent rotation and remove the retaining nut with the correct socket size (confirm size against the FSM), then separate the end link.Torque specSway Bar Link Nuts55 Nm (41 lb-ft)
- 5Disconnect lower ball jointVERIFY AGAINST FSM: The 2005 Viper rear suspension uses a multi-link arrangement. Confirm whether the lower connection to the knuckle is a tapered ball joint (castle nut) or a bolted control arm attachment before proceeding. If a ball joint is present, remove the cotter pin (if equipped) and castle nut, then use a ball joint separator to break the taper fit; if it is a bolted attachment, remove the through-bolt and nut instead.⚠The ball joint can release suddenly. Keep hands clear of the pinch point.Torque specBall Joint Nut88 Nm (65 lb-ft)
- 6Remove strut-to-knuckle boltsVERIFY AGAINST FSM: The 2005 Viper uses a coil-over shock on a multi-link rear suspension rather than a MacPherson strut. Confirm the shock's lower mounting location (typically to the lower control arm, not directly to the knuckle) and the number/size of fasteners before removal.Torque specStrut Bolts115 Nm (85 lb-ft)
- 7Disconnect upper control arm or camber linkThe Viper rear suspension uses an upper control arm or camber link connection to the knuckle. Remove the bolt or nut securing this connection using the appropriate socket (typically 18mm). If the connection uses an eccentric bolt for camber adjustment, mark the bolt orientation with paint or a marker before removal to aid in reinstallation alignment.
- 8Remove knuckle from hub assemblyWith all suspension connections disconnected, separate the knuckle from the wheel hub and bearing assembly. VERIFY AGAINST FSM: The rear hub/bearing assembly bolts to the knuckle from the rear. Confirm the exact bolt count and torque spec against the FSM before removal (commonly 3 or 4 bolts on this platform). The hub and bearing will remain with the vehicle.
- 9Inspect and clean mounting surfacesWith the knuckle removed, inspect all mounting surfaces, tapers, and bolt holes for damage, corrosion, or wear. Clean all mating surfaces with a wire brush and brake cleaner. Inspect the ball joint taper in the knuckle for elongation or damage. Check the hub mounting surface for runout or damage. Replace any damaged components before reassembly.
- 10Install new knuckle to hub assemblyPosition the new knuckle onto the wheel hub and bearing assembly, aligning the 4 bolt holes. VERIFY AGAINST FSM: Do not use anti-seize on torque-critical hub-to-knuckle fasteners unless specified; use threadlocker or install clean/dry per FSM. Install the hub-to-knuckle bolts (confirm count against FSM) and tighten in a cross pattern to the specified torque. Verify the knuckle is fully seated against the hub mounting face.
- 11Connect upper control arm or camber linkAlign the upper control arm or camber link with the knuckle mounting point. If an eccentric bolt was marked during removal, align it to the same orientation. Install the bolt and nut, tightening to finger-tight only at this stage. Final torque will be applied with vehicle weight on the suspension.
- 12Connect strut to knuckleAlign the shock absorber/strut mounting bracket with the knuckle. Install the 2 strut-to-knuckle bolts from the appropriate direction. Tighten both bolts to specification using an 18mm socket and torque wrench.Torque specStrut Bolts115 Nm (85 lb-ft)
- 13Connect lower ball jointInsert the lower ball joint stud into the knuckle taper. Ensure the taper is clean and seats fully. Install the castle nut and tighten to specification. Install a new cotter pin through the castle nut slots and ball joint stud hole, bending the ends to secure.Torque specBall Joint Nut88 Nm (65 lb-ft)
- 14Reconnect sway bar end linkConnect the sway bar end link to the knuckle or control arm mounting point. Install the nut while holding the ball stud shaft with an Allen key. Tighten to specification.Torque specSway Bar Link Nuts55 Nm (41 lb-ft)
- 15Install wheel speed sensorInstall a new O-ring on the wheel speed sensor if the old one shows any wear or damage. Apply a small amount of clean silicone grease (or install dry per FSM) to the O-ring to ease installation. Insert the sensor into the knuckle bore and install the mounting bolt, tightening to specification. Reconnect the electrical connector, ensuring it clicks into place.
- 16Install brake rotor and caliperSlide the brake rotor onto the wheel hub. Position the brake caliper over the rotor and align the mounting bolt holes. Install the 2 caliper mounting bolts and tighten to specification. Remove any caliper support wires or hangers used during the procedure.
- 17Install wheel and lower vehicleInstall the wheel and tire assembly. Thread the lug nuts by hand to prevent cross-threading. Tighten lug nuts in a star pattern to specification using a torque wrench. Lower the vehicle to the ground.Torque specWheel Lug Nuts142.4 Nm (105 lb-ft)
- 18Final torque suspension componentsWith the vehicle weight on the wheels, torque any suspension bushings or control arm bolts that were left loose during installation. This ensures proper bushing preload in the normal ride height position. Bounce the rear of the vehicle several times to settle the suspension before final torquing.
Reassembly
- Torque all fasteners in the reverse order of removal, ensuring suspension bushings are torqued with vehicle weight on wheels.
- Pump the brake pedal several times to restore proper caliper piston position before moving the vehicle.
- Verify ABS wheel speed sensor connector is fully seated and secured.
Verification
- Test drive the vehicle at low speed to verify no unusual noises or vibrations from the rear suspension.
- Verify ABS warning light does not illuminate, confirming proper wheel speed sensor operation.
- Schedule a four-wheel alignment as suspension geometry will have changed with knuckle replacement.
- Verify brake pedal feel is firm and proper before operating vehicle on public roads.
- Visually inspect all connection points for proper seating and torque after 50-100 miles of driving.
