This procedure covers the removal and installation of the front wheel bearing hub assembly on a 2005 Dodge Viper with the 8.3L V10 engine, including disconnection of the ABS sensor and brake caliper.

Warnings

⚠️Vehicle must be supported on jack stands rated for its weight. Never work under a vehicle supported only by a floor jack.

⚠The axle nut is torqued to 250 Nm (184 lb-ft). Loosen it while the vehicle is on the ground with the wheel installed to prevent hub rotation.

⚠Do not allow the brake caliper to hang by the brake hose. Support it with wire or a bungee cord to prevent hose damage.

ℹ️The ABS sensor is integrated into the hub assembly on this vehicle. No separate sensor replacement is required.

Preparation

Park vehicle on level ground and engage parking brake.
Place wheel chocks behind rear wheels.
Loosen front wheel lug nuts while vehicle is on the ground (do not remove).
Loosen but do not remove the axle nut while the wheel is on the ground and vehicle weight is preventing hub rotation. Remove the cotter pin first using a punch and cotter pin puller.
Lift front of vehicle with floor jack at designated jacking point.
Support vehicle securely on jack stands placed at manufacturer-specified support points.
Remove wheel and tire assembly completely.

Procedure

1
Remove Axle Nut
With the wheel removed and vehicle supported on jack stands, note that the front hub on this rear-wheel-drive vehicle is a bolt-on unit bearing/hub assembly. There is no front axle nut or cotter pin to remove; proceed directly to the brake and hub-bolt steps.
2
Disconnect ABS Sensor Harness
Locate the ABS wheel speed sensor electrical connector near the hub assembly. Press the connector release tab and disconnect the harness. Route the wire clear of the work area. Note the routing path for reinstallation.
3
Remove Brake Caliper Bracket Assembly
Remove the two brake caliper bracket bolts that secure the caliper and bracket assembly to the steering knuckle. These are large bolts requiring significant torque to remove. Once removed, carefully support the entire caliper and bracket assembly with wire or a bungee cord so no weight is on the brake hose. Do not disconnect the brake line.
Torque spec
Caliper Bracket Bolts120 Nm (88 lb-ft)
4
Remove Brake Rotor
With the caliper assembly removed, slide the brake rotor off the hub studs. If the rotor is seized to the hub face, use a dead blow hammer or brass hammer to tap it loose from behind. Do not damage the rotor face if reusing. Set rotor aside in a clean area.
5
Access Hub Mounting Bolts
The hub assembly is secured to the steering knuckle from behind with 4 bolts accessible from the back side of the knuckle. Access these bolts from behind the hub assembly. You may need to turn the steering to full lock (left or right depending on side being serviced) to improve access to the rear-mounted hub bolts.
6
Remove Hub Mounting Bolts
Remove all 4 hub mounting bolts from the rear of the steering knuckle. These bolts pass through the knuckle and thread into the hub assembly. Keep bolts organized for reinstallation unless replacing with new hardware.
7
Separate Hub from Knuckle
With all mounting bolts removed, pull the hub assembly forward and off the steering knuckle. If the hub is stuck to the knuckle, tap it gently with a dead blow hammer from behind or use a pry bar carefully to separate it. Avoid damaging the knuckle mounting surface.
8
Clean Mounting Surfaces
With the old hub removed, thoroughly clean the hub mounting surface on the steering knuckle using a wire brush. Remove all rust, corrosion, and old debris. Clean the hub pilot bore and mating surface on the knuckle. Inspect the knuckle for cracks or damage. Apply a thin coat of anti-seize compound to the knuckle mounting face to prevent future corrosion and aid future removal.
9
Install New Hub Assembly
Position the new hub assembly against the steering knuckle mounting surface, ensuring the pilot seats correctly. Ensure the hub is fully seated against the knuckle and the bolt holes align properly. Verify the ABS sensor wire is routed correctly and not pinched.
10
Install Hub Mounting Bolts
Apply medium-strength threadlocker to the threads of the 4 hub mounting bolts. Insert all 4 bolts from the rear of the knuckle and thread them into the hub assembly by hand. Once all bolts are started, tighten them in a cross pattern to ensure even seating. Torque all 4 bolts to specification in a cross pattern.
Torque spec
Wheel Bearing Hub Bolts110 Nm (81 lb-ft)
11
Install Brake Rotor
Slide the brake rotor back onto the hub studs. Ensure the rotor seats fully against the hub face. If using an old rotor, install it in the same orientation as removed if it has directional wear patterns.
12
Install Brake Caliper Bracket Assembly
Remove the support wire or bungee cord from the caliper assembly. Position the caliper and bracket over the rotor and align the mounting holes with the steering knuckle. Install both caliper bracket bolts and torque to specification in a cross pattern to ensure even clamping.
Torque spec
Caliper Bracket Bolts120 Nm (88 lb-ft)
13
Reconnect ABS Sensor Harness
Reconnect the ABS wheel speed sensor electrical connector. Ensure it clicks fully into place and the locking tab engages. Route the wire along its original path and ensure it will not contact any rotating components or be damaged during suspension travel.
14
Install Axle Nut and Wheel
Install the wheel and tire assembly and thread lug nuts by hand. The front hub is retained by its mounting bolts (installed earlier); there is no axle nut or cotter pin on this rear-wheel-drive front hub.n is fully seated and will not interfere with any components.
Torque spec
Axle Nut250 Nm (184 lb-ft)
15
Final Wheel Installation
Raise the vehicle slightly off the ground, torque the wheel lug nuts to manufacturer specification in a star pattern, then lower the vehicle completely to the ground. Remove jack stands and floor jack. Perform final lug nut torque verification with vehicle on the ground.

Reassembly

Reassembly is covered in the installation steps above.
Ensure all torque specifications are followed exactly, particularly the axle nut and hub mounting bolts.
Always use a new cotter pin for the axle nut; never reuse the old pin.
Verify the ABS sensor connector is fully seated and locked.

Verification

Test drive the vehicle at low speed in a safe area and listen for any abnormal noises from the wheel bearing area.
Verify the ABS warning light does not illuminate on the instrument cluster, confirming proper ABS sensor connection.
Check for smooth operation with no grinding, humming, or vibration from the replaced hub.
After the first 50-100 miles, re-verify the axle nut torque and cotter pin security.
Verify the wheel lug nuts remain properly torqued after initial drive cycle.
