Step-by-Step Instructions
Follow these steps carefully
1
Loosen lugs and support the vehicle
The 2017–2024 Genesis G80 does NOT have a MacPherson strut front suspension — it uses a FIVE-LINK / multi-link front suspension with coil springs. However, the damper + spring is cataloged and serviced as a 'strut assembly.' This is fundamentally different from the MacPherson guides in this group. The G80 is a heavy luxury sedan (~4,300–4,700 lbs depending on trim) — use high-capacity jack stands. Critical: verify your EXACT trim before ordering parts. The G80 spans two generations (DH 2017-2020, RG3 2021+) with RWD/AWD and electronic vs conventional dampers — parts are NOT interchangeable. Electronic dampers (CDC/ECS) were on the 2018–2019 G80 Sport 3.3T and upper 2021+ trims (ECS with Road Preview). If you have electronic dampers, you MUST disconnect the wiring before removal. Loosen lug nuts, jack up, support with stands.
🔧 Mechanic's note — Tom Becker
I loosen the G80 lugs and set the stands — then I shake the car hard. If it moves at all, I reset them. I am going to be under this Genesis torquing strut mounts, and my life is worth the extra two minutes.
2
Support the knuckle and disconnect links
Support the suspension with a jack — the G80's multi-link components are heavy. If your G80 has ELECTRONIC dampers (Sport 3.3T or upper trims with ECS), locate the electrical connector on the damper and disconnect it FIRST. Do not let the assembly hang by the wiring, and avoid shorting the connector. Disconnect the sway bar end link (separate service part on the G80 — verify whether it attaches to the damper body or control arm on your specific year). Disconnect the ABS sensor wire and brake hose from their brackets. The multi-link design means more components to work around than a MacPherson strut.
🔧 Mechanic's note — Tom Becker
I know if the connector doesn't click, it isn't seated. Push it firmly home — a half-seated connector throws a code a week later.
3
Separate the strut from the knuckle
Do not assume it's the same as a MacPherson knuckle with two through-bolts. Support the suspension components as you disconnect — the G80's parts are heavy. Keep track of all bolts and their positions.
4
Unbolt the upper mount and remove the strut
Access the upper mount from the engine bay — the G80's upper mount sits in a strut tower accessible from above. Unbolt the upper mount. Have a helper support the heavy damper assembly from below — at 4,300+ lbs vehicle weight, these components are substantial. Lower the assembly out through the wheel well. Note: if you have electronic dampers, ensure the wiring is fully disconnected and routed clear before removing. The upper mount on the G80 is a critical component — inspect it for cracking (a known issue on Genesis sedans where the strut can drive up toward the aluminum mount).
5
Install the new strut assembly
Install the new damper assembly — but FIRST verify it's the correct part: RWD vs AWD (different), electronic vs conventional (different — CARiD lists them separately), DH (2017-2020) vs RG3 (2021+) generation (different). Installing the wrong variant will cause fitment or electronic errors. Position the assembly in the tower and start the upper mount bolts. Connect the lower mount per Genesis service info for your trim. If electronic: reconnect the damper wiring harness — ensure the connector clicks and is routed away from moving parts. Reconnect the sway bar end link, ABS sensor, and brake hose to their brackets. Torque all fasteners to Genesis specifications (check service data — do not guess on this luxury vehicle).
6
Torque upper nuts, reinstall wheel, and align
Torque the upper mount nuts to Genesis spec (consult service data). Reinstall the wheel and torque lug nuts to spec in a star pattern. Lower the vehicle. The G80's multi-link suspension requires a professional alignment after damper replacement — the geometry is complex. If you have electronic dampers, the system may need calibration or a reset via diagnostic tool — check for warning lights. Test drive: the G80 should ride smoothly and quietly. Any clunking indicates loose mounts or incorrect parts. Given the G80's complexity (multi-link + possible electronic dampers + two generations), if you're unsure about any step, consult a Genesis specialist. This is not a simple MacPherson job.
🔧 Mechanic's note — Ray Delgado
I torque the G80 strut nuts and drive it, then I recheck those nuts — heat cycles and the first bumps settle everything, and I have found fasteners a quarter-turn looser than when I set them.
All Done!
Test your repair before closing everything up. If something doesn't work right, double-check your steps.
⚠️ Common Mistakes to Avoid
- • Not properly securing the vehicle before starting the repair
- • Over-tightening or under-tightening the strut mounting bolts
