This procedure covers the removal and replacement of the front sway bar (stabilizer bar) on a 2016-2021 Honda Civic with the 1.5L turbo engine, including disconnecting sway bar links and removing mounting brackets.

Warnings

Tools required

Parts

• Front sway bar (stabilizer bar) × 1 — 51300-TBA-A01 or aftermarket equivalent
• Sway bar bushings × 2 — 51306-TBA-A01 (recommend replacement)
• Sway bar bracket bolts × 4 — Use OEM specification if corroded

Preparation

1. Park vehicle on level surface and engage parking brake
2. Chock rear wheels securely
3. Loosen front wheel lug nuts while vehicle is on ground
4. Raise front of vehicle and support securely on jack stands at designated lift points
5. Remove both front wheels completely

Procedure

1. 1

   Access sway bar links
   From underneath the vehicle, locate the sway bar links connecting the sway bar ends to the lower control arms on both sides. The links are vertical components with ball joints at each end.
2. 2

   Disconnect passenger side sway bar link
   Insert a 6mm Allen key into the top of the sway bar link shaft to prevent it from spinning. Using a 14mm socket, remove the upper nut connecting the link to the sway bar. The link will remain attached to the control arm.

   Sway Bar Link Nuts55 Nm (41 lb-ft)
3. 3

   Disconnect driver side sway bar link
   Repeat the same process on the driver side: hold the link shaft with the 6mm Allen key and remove the upper nut with a 14mm socket. Both ends of the sway bar are now free from the links.

4. 4

   Remove sway bar bracket bolts
   Locate the two sway bar mounting brackets that secure the bar to the front subframe. Each bracket is held by two bolts. Using a 14mm socket, remove all four bracket bolts. Support the sway bar to prevent it from dropping.
   Torque spec

   Sway Bar Bracket Bolts45 Nm (33 lb-ft)
5. 5

   Remove sway bar and bushings
   Lower the sway bar down and maneuver it out from underneath the vehicle, working it past any steering components or brake lines. Remove the rubber bushings from the bar and inspect them for cracking, tearing, or excessive wear. Replace if damaged.
6. 6

   Clean mounting surfaces
   Use a wire brush to clean the sway bar mounting areas on the subframe where the brackets attach. Remove any rust, dirt, or old rubber residue to ensure proper seating of new components.
7. 7

   Install bushings on new sway bar
   Slide the new or reused bushings onto the replacement sway bar, positioning them in the marked locations where they will mate with the mounting brackets. Ensure the bushing split faces the correct direction (typically toward the rear of the vehicle).
8. 8

   Install sway bar into position
   Maneuver the sway bar up into position under the vehicle, aligning the bushings with the subframe mounting locations. The sway bar ends should be positioned near the control arm link attachment points on both sides.
9. 9

   Install mounting brackets and torque bolts
   Place the mounting brackets over the bushings and start all four bracket bolts by hand. Ensure bushings are properly seated in the brackets. Torque all four bracket bolts to specification using a torque wrench.

10. 10

    Reconnect sway bar links
    Align the sway bar ends with the upper ball joints of the sway bar links. Install the upper nuts on both sides, holding each link shaft with a 6mm Allen key to prevent spinning. Torque both nuts to specification.

11. 11

    Reinstall wheels
    Install both front wheels and hand-tighten the lug nuts in a star pattern. Lower the vehicle until the tires just touch the ground but the suspension is not fully loaded.
12. 12

    Final torque and lower vehicle
    Torque wheel lug nuts to 108 Nm (80 lb-ft) in a star pattern. Fully lower the vehicle to the ground and remove jack stands. Perform a final check of all fasteners.

Reassembly

1. Double-check that all sway bar bracket bolts and link nuts are torqued to specification
2. Verify that no brake lines, ABS wires, or other components are in contact with or pinched by the sway bar
3. Ensure bushings are properly seated and brackets are flush against subframe

Verification

• Test drive vehicle at low speed and verify there are no clunking or rattling noises from the front suspension
• Perform gentle turns in both directions to confirm sway bar is functioning properly
• Re-inspect all fasteners after 50-100 miles of driving to ensure nothing has loosened
• Check for proper steering response and stability during cornering
