Parts for your 2004 Honda Elysion-Gas struts

2004 Honda Elysion gas struts — fitted, what they do, and how to service them

Gas struts are relevant to the 2004 Honda Elysion. Technical references including Honda’s Electronic Parts Catalogue (RR1–RR4) and the factory workshop manual list gas‑charged “Tailgate Stays” for the rear liftgate, while the bonnet uses a mechanical prop rod rather than struts. The sliding doors are cable/motor and track‑driven (manual or power), not gas‑spring assisted.

On the Elysion, the tailgate gas struts counterbalance the weight of the rear door so it lifts smoothly and stays up without a fight. They’re sealed, nitrogen‑charged dampers designed to give controlled motion and hold. Over time, seals harden and the gas charge fades, especially with heat cycles and heavy use.

Owners generally notice tired struts on colder mornings first. The tailgate feels heavier, rises only halfway, or sags down unexpectedly — not ideal when loading groceries or gear.

• Common signs they’re due: tailgate won’t stay up, jerky movement, oily film on the strut shaft, and needing two hands to lift.
• Typical service life: often 5–10 years, shorter in harsh climates or if the tailgate is frequently loaded with accessories.

Replacement is straightforward and best done in pairs to keep balance and hold‑force even.

1. Support the tailgate securely with a prop or a helper. Safety first — these doors are heavy.
2. Pop the spring clips at each end of the old strut and pull the sockets off the ball studs.
3. Match the new struts by length, end‑fittings and rated force (in Newtons) as per the Elysion spec from Honda EPC or reputable OEM catalogues.
4. Clip new struts on, small‑diameter rod end typically to the body side. Ensure clips are fully seated.

Care tips: don’t grease the chrome shaft (it attracts grit and damages seals). Keep the ball studs lightly lubricated and check hinge alignment so the strut isn’t side‑loaded. If one side feels lazy, replace both. Gas struts aren’t meant to be regassed in normal service — once they fade, swap them.

Because the bonnet uses a prop rod on this model, there’s nothing to service there beyond ensuring the rod is secure and the grommets are intact. The sliding doors rely on rollers, cables, and motors, no gas struts are used in those systems on the Elysion platform.

Popular questions about 2004 Honda Elysion gas struts

How long do the Elysion’s tailgate gas struts usually last?
Service life varies with climate and use, but many see 5–10 years before noticeable fade. Cold weather often exposes weak struts first. If the tailgate hesitates or drifts down, plan for a pair replacement.

Can the original struts be regassed, or should they just be replaced?
They’re sealed units and generally not serviceable. Re‑gassing is uncommon and not recommended for OE‑style struts. Replacement with correct‑spec units is the reliable fix.

Why doesn’t the Elysion have gas struts on the bonnet or sliding doors?
Per Honda documentation, the bonnet uses a simple prop rod for cost, weight and service access reasons. The sliding doors run on tracks with rollers and (on power models) cables and motors — their motion and geometry don’t suit gas springs.
