Parts for your 2003 Subaru Impreza-Gas struts

2003 Subaru Impreza gas struts

Based on the Subaru Factory Service Manual for MY2002–2003 Impreza (Body section: “Back Door” and “Engine Hood”) and the Subaru FAST electronic parts catalogue for GD/GG, gas-charged struts are fitted to the rear hatch of the 2003 Impreza Sportswagon (GG). The sedan’s boot uses torsion bars rather than gas struts, and the bonnet on both sedan and wagon uses a prop rod from factory (no OEM bonnet gas struts). Aftermarket bonnet kits exist, but they’re not original equipment. That means gas struts are absolutely relevant for the wagon’s tailgate on a 2003 Subaru Impreza.

On the Sportswagon, the rear hatch gas struts do the heavy lifting. They counterbalance the door so it opens smoothly, holds at full height, and doesn’t slam shut on windy days. When they’re healthy, the hatch pops up with a gentle lift and stays put. When they’re tired, the hatch sags, struggles to rise in cold weather, or drops unexpectedly — which is both annoying and unsafe.

As part of routine servicing, it’s smart to check for tell-tale signs: oil misting around the shaft, a weak or jerky lift, or a hatch that won’t stay fully open. Because struts wear gradually and in pairs, replacement of both sides at the same time keeps the hatch balanced and prevents uneven loading on hinges and glass.

Replacement is straightforward for a competent DIYer or any workshop: support the hatch with a prop or helper, flick up the retainer clips with a small flat-blade screwdriver, and swap the struts one at a time. No lubrication is required — in fact, avoid spraying the shaft, as oils can damage the seals. Keep the chrome rod clean, don’t paint it, and don’t force the hatch against the stops. Note that gas struts are temperature-sensitive, a strut that feels weaker on a frosty Christchurch morning may perk up by afternoon, but persistent weakness means it’s time to replace.

Choosing the right part matters. Select quality, vehicle-specific units matched to the GG tailgate’s force rating so the hatch opens reliably without over-stressing mounts. When fitted correctly, fresh gas struts restore that easy, one-hand hatch operation that makes daily use a breeze, whether loading the pram, the esky, or the weekend’s surf gear.

• Replace in pairs to maintain balance and holding force
• Support the hatch during replacement — don’t rely on a weak strut
• Avoid greasing the shaft, keep it clean and dry

FAQs

How long do rear hatch gas struts last on a 2003 Impreza wagon?
Service life varies with climate and usage, but many owners see 5–10 years. Frequent use, heat, and contamination shorten life. If the hatch won’t stay up or lifts sluggishly, they’re due.

Can the 2003 Impreza sedan use gas struts on the boot?
The sedan’s boot uses torsion bars from factory and doesn’t have gas struts. Aftermarket conversions are uncommon, most owners retain the OEM torsion setup and simply adjust or service it if needed.

Does the 2003 Impreza have bonnet gas struts?
No, the bonnet uses a prop rod as per the factory service manual. Aftermarket bonnet strut kits are available, but they’re not OEM. If fitting a kit, choose one designed for the GD/GG body to avoid misalignment or hinge stress.
