Sway Bar Bushing - Rear

Replace the rear sway bar bushings on a 2023 Chevrolet Bolt EUV to restore proper anti-roll bar function and eliminate clunking noises during cornering.

Warnings

Tools required

Parts

• Rear sway bar bushing (left) × 1 — 84658635 or equivalent
• Rear sway bar bushing (right) × 1 — 84658635 or equivalent

Preparation

1. Park vehicle on level surface and engage parking brake
2. Chock front wheels to prevent vehicle movement
3. Raise rear of vehicle using floor jack at designated rear lift point
4. Support vehicle securely with jack stands under rear subframe or axle beam
5. Remove rear wheels if additional access is needed (optional for this job)

Procedure

1. 1

   Locate rear sway bar and bushings
   Position yourself under the rear of the vehicle. The rear sway bar runs laterally across the rear suspension. Identify the two sway bar bushing brackets that clamp the bar to the subframe, located near the center of the bar on each side of the vehicle centerline.
2. 2

   Remove first sway bar bracket bolts
   Using a 13mm socket, remove the two bolts securing the first sway bar bracket to the subframe. Support the bracket with your hand as you remove the second bolt to prevent it from falling. Remove the bracket and the old bushing from the sway bar.
3. 3

   Clean sway bar mounting surface
   Use a wire brush to clean the area of the sway bar where the bushing sits, removing any dirt, rust, or old rubber residue. Clean the mounting surface on the subframe as well. Inspect the sway bar for cracks or damage in this area.
4. 4

   Install new bushing on first side
   Position the new sway bar bushing around the sway bar, ensuring the split in the bushing faces forward or as marked by directional indicators on the bushing. Apply a light coating of silicone spray to the inside of the bushing if desired to ease installation and reduce noise. Do not use petroleum-based lubricants.
5. 5

   Install first bracket and torque bolts
   Place the bracket over the bushing, aligning the bolt holes with the subframe. Start both bracket bolts by hand to ensure proper thread engagement. Torque both bracket bolts to specification in a cross pattern.

6. 6

   Remove second sway bar bracket
   Repeat the removal process for the opposite side sway bar bracket. Remove both bolts, then remove the bracket and old bushing from the sway bar.
7. 7

   Clean and install second bushing
   Clean the second sway bar mounting area with a wire brush. Position the new bushing around the bar with proper orientation, ensuring the split faces the same direction as the first bushing.
8. 8

   Install second bracket and torque bolts
   Install the second bracket over the bushing, start both bolts by hand, and torque to specification in a cross pattern. Verify both brackets are fully seated against the subframe.

9. 9

   Inspect sway bar links
   While under the vehicle, inspect both sway bar links connecting the bar to the suspension arms. Check for torn boots, excessive play, or damage. If links show wear, note for future replacement.

Reassembly

1. If wheels were removed, reinstall and torque lug nuts to specification in a star pattern
2. Remove jack stands and carefully lower vehicle to ground
3. Perform final torque check on all fasteners
4. Remove wheel chocks

Verification

• Start vehicle and turn steering wheel full left and full right while stationary to load the sway bar, listening for any clunking or binding
• Test drive vehicle over bumps and through turns at low speed, verifying elimination of any previous clunking noises
• Perform visual inspection under vehicle after test drive to confirm brackets remain tight and properly seated
• Re-torque bracket bolts after 50-100 miles of driving as a precautionary measure
