Replacement of the rear sway (anti-roll) bar on a 2024 Tesla Model S Plaid. The rear subframe area is tight on Plaid due to the rear drive unit and air suspension components — work carefully around suspension and HV-adjacent hardware.
Warnings
⚠️Do NOT touch, cut, or route tools near any orange HV cabling along the floor pan or near the rear drive unit. If you encounter an orange cable, stop work.
⚠Model S Plaid has air suspension. Disable suspension auto-leveling via the touchscreen (Service Mode 'Jack Mode' or equivalent vehicle-on-jack setting) before lifting to prevent the compressor from cycling and to avoid damaging level sensors.
⚠Aluminum body and subframe components — do not strike with a steel hammer. Use a dead-blow or rubber mallet only.
⚠Sway bar bracket and link bolts are CRITICAL torque items. Under-torqued hardware can back out and cause loss of stability control feel; over-torqued can strip aluminum threads.
ℹ️Note orientation of the sway bar before removal — bends and end-link mounts are not symmetric front-to-back.
Tools required
Two-post lift or four jack stands rated for EV curb weight (4,800+ lb)Essential
Torque wrench (20–150 Nm range)Essential
Metric socket set (deep and shallow)Essential
Metric combination wrench setEssential
Allen/hex key set (for holding sway bar end link studs)Essential
Breaker bar
Penetrating oil
Trim panel removal tools (for any underbody aero shielding)Essential
Transmission jack or second jack to support sway bar during removal
Parts
- Rear sway bar (anti-roll bar) × 1 — OEM Tesla Model S Plaid rear sway bar — verify by VIN
- Sway bar bushings (saddle/D-bushings) × 2 — OEM-spec rear sway bar bushing set
- Sway bar end links (recommended if worn) × 2 — OEM-spec rear sway bar end link
Preparation
- Park on level ground, place in P, engage parking brake.
- Exit ALL doors with the key fob away from the vehicle. Wait at least 2 minutes for HV systems to fully de-energize, even on this non-HV job.
- Disconnect the low-voltage battery. On 2024 Model S Plaid this is typically the 16V lithium unit located under the rear seat (verify by VIN — some units remain in the frunk).
- DO NOT touch, cut, or pierce ANY orange cable — these are high-voltage and lethal.
- If at any point you encounter an orange cable, an HV component, or are unsure if a system is de-energized: STOP and consult a Tesla-certified technician.
- Enable Jack Mode / service lift mode on the touchscreen before raising the vehicle to disable air suspension self-leveling.
- Loosen rear lug nuts while the vehicle is on the ground.
- Raise the vehicle on a lift or jack stands using the manufacturer-specified lift pads only — never lift on the battery pack edges.
- Remove both rear wheels.
Procedure
- 1Remove rear underbody aero shieldingRemove the rear underbody aero panels and any heat shielding necessary to access the rear sway bar and its brackets on the rear subframe. Use trim tools and store fasteners by location — Tesla aero panels use a mix of plastic clips and small Torx/hex bolts.⚠Aero panels are structural for thermal/aero performance. Do not omit or distort them on reinstall.
- 2Survey work area and identify HV routingVisually trace any orange HV cabling and high-voltage components in the rear subframe area. Confirm none of your wrench paths cross or contact orange cabling. Also identify ABS/ride-height sensor wiring near the rear control arms — these are easily damaged.⚠️If an orange cable obstructs sway bar removal, STOP. This job should not require disturbing HV cabling.
- 3Disconnect sway bar end links from sway barAt each end of the rear sway bar, hold the end link stud with an Allen/hex key and remove the nut securing the end link to the sway bar arm. Inspect end-link bushings/ball joints for play; replace if worn. Swing the freed end link out of the way.Torque specSway Bar Link61 Nm (45 lb-ft)
- 4Support the sway barPlace a transmission jack or a helper hand under the sway bar to support its weight before unbolting the brackets. The bar is light but awkward; an unsupported drop can damage the rear subframe finish or nearby sensors.
- 5Remove sway bar bracket boltsRemove the bolts securing the two sway bar saddle brackets to the rear subframe. Retain the brackets — they are reused unless damaged. Note bushing orientation (slit typically faces forward or as marked).Torque specSway Bar Bracket Bolts47 Nm (35 lb-ft)
- 6Maneuver sway bar out of vehicleCarefully rotate and lower the sway bar out from under the rear of the vehicle. Clearance around the rear drive unit, half shafts, and air suspension lines is tight — protect air lines and any wiring harnesses with shop rags as you maneuver.⚠Do not pry against air suspension lines or HV cabling. If the bar will not clear, recheck for an obstructing fastener rather than forcing it.
- 7Transfer / replace bushingsSlide the old D-bushings off the sway bar. Install new bushings on the new bar (or old bar if reusing) in the same orientation. Lubricate only with the bushing manufacturer's specified silicone-based lubricant — never use petroleum grease, which will degrade the rubber.
- 8Install new sway barLift the new (or rebuilt) sway bar into position, oriented identically to the original. Loosely fit both saddle brackets over the bushings and start all bracket bolts by hand to avoid cross-threading aluminum subframe threads.⚠Aluminum threads strip easily. Always start bolts by hand and confirm smooth engagement before applying tool torque.
- 9Torque sway bar bracket boltsTighten the sway bar bracket bolts evenly side-to-side, then torque to specification.Torque specSway Bar Bracket Bolts47 Nm (35 lb-ft)
- 10Reconnect sway bar end linksReattach each end link to the sway bar arm. Hold the stud with an Allen key to prevent rotation while torquing the nut. If the end link bolts pass through the link body and into the bar, use the Sway Bar Link spec instead of the Sway Bar Link Nuts spec — verify which fastener you are tightening.Torque specSway Bar Link61 Nm (45 lb-ft)
Reassembly
- Reinstall the rear underbody aero shielding, ensuring all clips and fasteners are seated — missing panels affect range and thermal management.
- Reinstall rear wheels. Snug lug nuts by hand, lower the vehicle to the ground, then torque lug nuts in a star pattern to the verified spec.
- Reconnect the low-voltage battery (16V/12V as applicable).
- Exit Jack Mode on the touchscreen and allow the air suspension to re-level fully before driving.
Verification
- With the vehicle on the ground and air suspension self-leveled, visually confirm both sway bar saddle brackets sit flush and the bar is centered in the chassis.
- Grab each end of the sway bar and attempt to twist — there should be no clunking from bushings or end links.
- Test drive on a known-smooth road, then on a road with one-wheel bumps. Listen for clunks over expansion joints, which would indicate loose end links or bushings.
- Perform a moderate cornering test at low speed — body roll should feel symmetric left vs. right.
- Re-check sway bar bracket bolt and end link torque after the first 100–500 miles, as is good practice for any CRITICAL suspension fastener.
- Note: Tesla recommends a brake fluid service every 2 years and tire rotation every 6,250 miles — if either is due, address while the vehicle is already on the lift.
