Parts for your 2015 Mitsubishi Outlander-Bump stops

2015 Mitsubishi Outlander bump-stops

Bump-stops are relevant and fitted to the 2015 Mitsubishi Outlander. Factory service literature and OEM parts catalogues for the 2014–2016 Outlander list front strut jounce bumpers and rear suspension bump-stops, and major aftermarket catalogues (e.g., KYB, Monroe) supply compatible bump-stop/boot kits. Those technical sources confirm the Outlander uses bump-stops as standard equipment.

On this Outlander, bump-stops act like compact, secondary cushions that come into play right at the end of the suspension’s travel. Their job is to prevent metal-on-metal bottoming, protect the struts and shocks from impact damage, and keep the ride controlled when the car hits big potholes, sharp speed humps, or carries a heavy load. They also quieten harsh knocks and help the vehicle hold its line by limiting excessive body movement at full compression.

The front of the 2015 Outlander uses MacPherson struts, each with a jounce bumper tucked under the dust boot on the strut shaft. The rear multi-link setup also uses bump-stops on each side. Because they’re made from microcellular polyurethane foam or similar, they can harden, crack or perish over time—especially if exposed to leaking shock oil or UV and road grime when the boot is torn.

As part of routine servicing, it’s smart to inspect bump-stops any time the struts/shocks are checked or replaced—typically around 60,000–100,000 km, or sooner if the vehicle tows, tackles rough roads, or runs heavier loads. If they’re missing, split, oil-soaked, or severely compressed, replace them. They’re inexpensive and can save the cost of a premature damper or mount failure.

• Tell-tales for worn bump-stops: a sharp thud on big hits, frequent bottoming out, torn/loose dust boots, and a harsher, crashy ride.

When replacing, go for OE or quality aftermarket units matched to the Outlander. Replace in axle pairs (both fronts or both rears). If the struts are coming out, add new dust boots at the same time—many kits bundle boot and bump-stop together. After front strut work, a wheel alignment is recommended to keep tyre wear tidy and steering feel consistent. For Outlanders that tow or see corrugations, consider a progressive heavy-duty bump-stop matched to the damper and spring rate—this can tame big compressions without making everyday ride quality too firm.

Popular questions about 2015 Mitsubishi Outlander bump-stops

How do you know the bump-stops need replacing on a 2015 Outlander?
Owners will usually notice a hard thud over speed humps or potholes, as if the suspension is “slamming” at the end of its travel. A quick visual check when the wheel is off can reveal perished foam, cracking, missing chunks, or torn dust boots. Any oil on the stop points to a leaking damper, which should be addressed at the same time.

How often should bump-stops be inspected or replaced?
They’re not a fixed-interval item, but checking them every major service or whenever struts/shocks are inspected (roughly 60,000–100,000 km) is good practice. Replace them if damaged, excessively hardened, or when fitting new dampers—doing them together saves labour and helps protect the fresh suspension.

Can bump-stops be upgraded for towing or rough roads?
Yes. Progressive, higher-capacity bump-stops can add support near full compression, reducing bottoming when towing or loaded, and improving control on corrugations. They should be chosen to suit the Outlander’s springs and dampers, so ride comfort isn’t compromised in everyday driving.
