Parts for your 2023 Mitsubishi Eclipse cross-Bump stops

2023 Mitsubishi Eclipse Cross bump-stops

Bump-stops are absolutely fitted and relevant on the 2023 Mitsubishi Eclipse Cross. Technical references including the Mitsubishi Factory Service Manual (Suspension section), the Mitsubishi ASA electronic parts catalogue, and major damper manufacturers’ catalogues for Eclipse Cross strut boot kits all list a jounce bumper (bump-stop) on the front MacPherson struts and a rear bump-stop integral to the shock assembly or mounted to the body/axle depending on variant. That means every big hit is cushioned by a dedicated stopper to protect the suspension and body.

On this model, the bump-stop acts as a progressive cushion near the end of suspension travel. It prevents the strut or shock from bottoming out metal-to-metal, controls extreme body movement, helps keep the spring seated, and reduces noise, vibration, and harshness on corrugated or potholed roads common around Australia and New Zealand. By taking the sting out of deep compression, it protects strut internals, upper mounts, control arm bushings, and even helps maintain alignment and tyre contact during sharp dips or heavy loads.

Servicing-wise, it’s smart to inspect the bump-stops whenever the wheels are off or during brake and tyre rotations—say every 20,000–30,000 kilometres. They live under the dust boots on the struts and shocks, and over time the foam or polyurethane can crack, crumble, or detach. If the dust boot is torn, grit will chew the bump-stop and damper shaft quicker. Replace bump-stops in axle pairs and choose OE or quality aftermarket items designed for the Eclipse Cross to keep the progression and ride height right. After any front strut removal, book an alignment check.

• Signs of trouble: harsh “thud” on big bumps, visible cracks or missing pieces, oily or shiny witness marks where the suspension is bottoming, torn boots, or a saggy, unsettled ride on fast dips.
• Best times to replace: when fitting new shocks/struts, after heavy off-road or towing duty, or around the 80,000–120,000 km mark depending on use.

Running larger loads, towing, or accessory weight? Confirm bump-stop condition and travel to avoid frequent bottoming. Lowered or lifted setups may need revised bump-stop length, trimming or extended stops should only be done to manufacturer guidance so travel and safety aren’t compromised.

Popular questions

Do the front and rear of a 2023 Eclipse Cross both have bump-stops?
Yes. The front MacPherson struts use foam jounce bumpers under the dust boots. The rear uses a bump-stop integrated with the shock or mounted near the axle/body depending on drivetrain. This layout is confirmed in the factory service documentation and parts listings for the model year.

How often should bump-stops be replaced on a 2023 Eclipse Cross?
They don’t have a strict interval, but they should be inspected at regular services and replaced if cracked, missing, or when replacing shocks/struts. Many drivers see replacement around 80,000–120,000 km, sooner if regularly travelling corrugated roads or carrying heavy loads.

Can bump-stops be changed without replacing the shocks or struts?
Front bump-stops usually require strut removal to access under the boot, so it’s efficient to replace them with new struts. Rear access varies by configuration—some can be serviced with the shock out only. After front strut work, plan for a wheel alignment.
