Sway Bar - Front

This procedure removes and replaces the front sway bar (stabilizer bar) on a 2008 Dodge Viper, including disconnecting the end links and removing the frame mounting bushings.

Warnings

Tools required

Parts

• Front sway bar × 1 — Use OEM specification
• Sway bar bushing set (frame mounts) × 1 — Use OEM specification
• Sway bar end links (if worn) × 2 — Use OEM specification

Preparation

1. Park vehicle on a level, solid surface and engage parking brake
2. Place wheel chocks behind rear wheels
3. Loosen front wheel lug nuts while vehicle is on the ground
4. Raise front of vehicle with floor jack at designated jacking points
5. Support vehicle securely on jack stands placed under the frame rails
6. Remove both front wheels
7. Spray penetrating oil on sway bar end link nuts and frame bushing bracket bolts if corrosion is present, allow to soak 10-15 minutes

Procedure

1. 1

   Disconnect driver side sway bar end link
   Locate the sway bar end link connecting the sway bar to the lower control arm on the driver side. Hold the ball joint stud stationary with the appropriately sized wrench/hex tool, then remove the upper nut securing the end link to the sway bar (verify nut and stud sizes against the 2008 Viper service manual). The end link should now be free from the sway bar. Allow the end link to hang from the lower control arm.
2. 2

   Disconnect passenger side sway bar end link
   Repeat the same process on the passenger side. Using a 15mm wrench to hold the ball joint stud, remove the upper nut securing the end link to the sway bar using a 15mm socket. Allow the end link to hang from the lower control arm.
3. 3

   Remove driver side sway bar frame bushing bracket
   Locate the sway bar frame bushing bracket bolted to the underside of the frame rail on the driver side. Remove the frame bushing bracket bolts securing the bracket to the frame (verify bolt count and size against the 2008 Viper service manual). Lower the bracket and bushing away from the frame. Note the orientation of the bushing split for reinstallation.
4. 4

   Remove passenger side sway bar frame bushing bracket
   Locate the sway bar frame bushing bracket on the passenger side. Remove the 2 bolts securing the bushing bracket to the frame using a 19mm socket. Lower the bracket and bushing away from the frame.
5. 5

   Remove sway bar from vehicle
   With both end links disconnected and both frame bushing brackets removed, carefully maneuver the sway bar out from under the vehicle. The bar may need to be rotated or angled to clear the lower control arms and frame. Take note of the bar's orientation and routing for reinstallation.
6. 6

   Inspect and prepare bushings
   Remove the old bushings from the frame bushing brackets. Inspect the brackets for damage or distortion. Clean the sway bar mounting surfaces on the frame with a wire brush. If reusing the sway bar, clean the bushing contact areas on the bar. Install new bushings into the frame brackets with the split facing toward the rear of the vehicle. Apply a light coating of silicone lubricant to the inside of the new bushings to prevent squeaking.
7. 7

   Install sway bar into position
   Maneuver the new or cleaned sway bar into position under the vehicle, ensuring the end link mounting points are oriented toward the lower control arms and the bar is centered side-to-side. Position the bar through the frame bushings so the bushing brackets can be reinstalled.
8. 8

   Install driver side frame bushing bracket
   Position the driver side bushing bracket over the sway bar and align with the frame mounting holes. Install the 2 bracket bolts and snug them by hand. Do not fully torque at this time to allow the bar to settle into position.
9. 9

   Install passenger side frame bushing bracket
   Position the passenger side bushing bracket over the sway bar and align with the frame mounting holes. Install the 2 bracket bolts and snug them by hand. Verify the sway bar is centered and the bushings are properly seated before proceeding.
10. 10

    Connect sway bar end links
    Lift each end of the sway bar to align with the end link studs. Install the upper nuts on both driver and passenger side end links and tighten using a 15mm socket while holding the ball joint stud with a 15mm wrench. Snug the nuts but do not fully torque at this time.
11. 11

    Torque frame bushing bracket bolts
    With the suspension at its natural resting position on the jack stands, torque the frame bushing bracket bolts to specification. Torque each frame bushing bracket bolt to the factory specification (verify against the 2008 Viper service manual) in a criss-cross pattern.
12. 12

    Torque end link nuts
    Torque the end link upper nuts to specification while holding the ball joint stud with a wrench to prevent spinning. Torque each end link nut to the factory specification (verify against the 2008 Viper service manual).
13. 13

    Reinstall wheels and lower vehicle
    Reinstall both front wheels and hand-tighten the lug nuts in a star pattern. Remove the jack stands and carefully lower the vehicle to the ground. With the vehicle weight on the wheels, torque the lug nuts to the factory specification (verify against the 2008 Viper service manual, approximately 110 ft-lbs) in a star pattern.

Reassembly

1. Ensure all fasteners are torqued to specification with the vehicle at normal ride height or on the ground
2. Double-check that end link ball joint studs were held stationary during nut tightening to prevent internal damage
3. Verify sway bar does not contact any suspension components, brake lines, or body panels through full suspension travel

Verification

• Start the vehicle and turn the steering wheel lock-to-lock while stationary to verify no binding or interference
• Test drive the vehicle and listen for any clunking, rattling, or squeaking noises from the front suspension
• Perform several moderate-speed turns in both directions to verify proper sway bar function and handling feel
• After the first 50-100 miles, re-check all sway bar fastener torques to ensure nothing has loosened
