Sway Bar - Rear

This procedure covers the removal and replacement of the rear sway bar (anti-roll bar) on a 2024 Rivian EDV 500 delivery van, including disconnecting end links and mounting brackets.

Warnings

Tools required

Parts

• Rear sway bar × 1 — Use OEM specification
• Sway bar mounting bushings × 2 — Use OEM specification
• Sway bar end links (if damaged) × 2 — Use OEM specification

Preparation

1. Park vehicle on level ground and apply parking brake
2. Place wheel chocks in front of front wheels
3. Power off vehicle completely and ensure it cannot be activated during service
4. Raise rear of vehicle using floor jack at manufacturer-specified rear lift points
5. Support vehicle with appropriately rated jack stands on both sides
6. Remove both rear wheels to access sway bar components
7. Inspect sway bar, end links, and bushings for wear or damage
8. Apply penetrating lubricant to all sway bar fasteners and allow to soak

Procedure

1. 1

   Support rear suspension
   Position a floor jack under the rear axle or suspension component near one side to slightly compress the suspension. This reduces tension on the sway bar and end links. Do not fully support the weight, just take up slack.
2. 2

   Disconnect driver side end link
   Locate the rear sway bar end link on the driver side connecting the sway bar to the suspension arm or axle housing. Remove the lower mounting bolt/nut securing the end link to the suspension component. Then remove the upper bolt/nut connecting the end link to the sway bar. Remove the end link and set aside.
3. 3

   Disconnect passenger side end link
   Reposition the floor jack to the passenger side of the rear suspension to slightly compress that side. Remove the lower mounting bolt/nut securing the passenger side end link to the suspension component. Then remove the upper bolt/nut connecting the end link to the sway bar. Remove the end link.
4. 4

   Remove driver side sway bar bracket
   Locate the sway bar mounting bracket on the driver side of the rear axle or subframe. The bracket holds the sway bar to the chassis via a bushing. Remove the two or more bolts securing the bracket to the frame. Note the orientation of the bracket and bushing for reassembly.
5. 5

   Remove passenger side sway bar bracket
   Support the sway bar by hand or with a bungee cord to prevent it from falling. Remove the bolts securing the passenger side mounting bracket to the frame. Remove the bracket and bushing, noting their orientation.
6. 6

   Remove rear sway bar
   Carefully maneuver the rear sway bar out from its mounting position. It may need to be rotated or angled to clear suspension components, the axle housing, or brake lines. Take care not to damage ABS sensors, brake lines, or wiring harnesses during removal.
7. 7

   Inspect and clean mounting points
   With the sway bar removed, inspect all frame mounting points for corrosion, damage, or elongated bolt holes. Clean mounting surfaces with a wire brush. Inspect the removed sway bar for cracks, bends, or damage. Check end links for worn ball joints or torn boots.
8. 8

   Install new bushings on sway bar
   If replacing bushings, clean the sway bar surface where bushings mount. Apply a light coating of silicone-based lubricant (not petroleum-based) to the inside of the new bushings. Install the bushings onto the sway bar in the correct orientation, typically with the split facing forward or as marked.
9. 9

   Position new or existing sway bar
   Carefully maneuver the sway bar (with bushings installed) into position under the vehicle. Align the bushings with the frame mounting points. Ensure the bar is centered side-to-side and the end link mounting points are properly oriented toward the suspension attachment points.
10. 10

    Install sway bar mounting brackets
    Position the mounting brackets over the bushings on both sides. Align bracket bolt holes with frame mounting holes. Install mounting bolts hand-tight initially. Ensure bushings are properly seated in brackets and not pinched or twisted.
11. 11

    Install end links
    Install the sway bar end links, connecting the upper end to the sway bar and the lower end to the suspension component. Install bolts and nuts hand-tight. You may need to use the floor jack to adjust suspension height to align bolt holes.
12. 12

    Torque all fasteners
    With the vehicle at normal ride height (on jack stands simulating loaded position), torque all sway bar mounting bracket bolts and end link fasteners. Since specific torque values are not available in the database, refer to Rivian OEM service information or use standard commercial vehicle torque specifications for the bolt size and grade. Typical values for M12 bolts are 70-85 ft-lbs for brackets and 50-65 ft-lbs for end links, but verify with factory specifications.

Reassembly

1. Reinstall both rear wheels and torque lug nuts to manufacturer specification (typically 140-150 ft-lbs for commercial vehicles, verify with door jamb sticker)
2. Lower vehicle from jack stands carefully, ensuring stability
3. Remove jack stands and lower vehicle completely to ground
4. Perform a final torque check on all sway bar components with vehicle at normal ride height if possible
5. Remove wheel chocks

Verification

• Bounce each rear corner of the vehicle to verify the sway bar is functioning and no rattles or clunks are present
• Visually inspect all connections to ensure hardware is tight and properly seated
• Test drive vehicle at low speed in a safe area, making gentle turns to verify proper sway bar operation and no abnormal noises
• Recheck all fastener torques after 50-100 miles of driving
• Monitor vehicle handling for any signs of looseness or abnormal behavior
