Parts for your 2017 Mitsubishi Outlander-Bump stops

2017 Mitsubishi Outlander bump-stops

Based on technical documentation, bump-stops are absolutely fitted to the 2017 Mitsubishi Outlander and are relevant for servicing. The Mitsubishi Motors Factory Service Manual for the ZJ/ZK/ZL Outlander (2014–2019) lists a “bump stopper” within the front MacPherson strut assembly (Group 33A) and a “rear suspension stopper” in the multi-link rear (Group 34). The Mitsubishi ASA electronic parts catalogue for the GF/GG series also shows dedicated front and rear stoppers. Major suspension catalogues from brands like KYB and Monroe include jounce bumper/dust boot kits for this model, further confirming their presence.

On the 2017 Outlander, bump-stops (also called jounce bumpers) act as compact safety cushions in the suspension travel. They’re designed to compress progressively on big hits—think deep potholes, speed humps taken a bit briskly, heavy loads, or towing—to prevent metal-to-metal contact. That extra layer of control protects the struts and shocks, helps stabilise the chassis at the end of travel, reduces nasty thuds, and preserves alignment components over time.

Up front, the Outlander’s bump-stop is typically integrated with the strut dust boot. Down the back, the stopper works with the rear shock and body mounting to manage jounce travel. They’re usually made from microcellular polyurethane foam, which gives a smooth ramp-up in firmness as it compresses.

During routine servicing, they deserve a quick look. Heat, age, road grime and fluid exposure can make the foam crack, crumble or collapse. If a bump-stop is perished—or if the dust boot is torn—the car can bottom out more easily, leading to a sharp bang on rough roads and extra stress on the dampers. Because access to the fronts requires strut removal and a spring compressor, many workshops replace bump-stops and boots whenever fitting new struts. The rears are often simpler, but best practice is to replace in axle pairs to keep handling balanced.

• Signs they need attention: harsh thuds over bumps, evidence of bottoming with a load, visible cracking or missing pieces, torn dust boots, or oil-soaked, mushy foam.
• Service tips: inspect at each major service or every 20,000–30,000 km, renew with OE-quality foam units, always pair new boots with bump-stops, and carry out a wheel alignment after front strut work.

Owners who frequently tow, carry full crews, or tackle corrugated roads should be especially diligent—healthy bump-stops help the Outlander stay composed and protect the suspension when it’s working hardest.

FAQs

Does a 2017 Mitsubishi Outlander have bump-stops front and rear?
Yes. The front MacPherson struts include an integrated bump-stop within the dust boot, and the rear suspension uses a stopper to control end-of-travel compression. This is documented in the factory service manual and parts catalogue for the ZJ/ZK/ZL series.

How often should bump-stops be replaced on a 2017 Outlander?
There’s no fixed interval, replacement is condition-based. Many workshops renew bump-stops and boots when fitting new struts/shocks (often around 80,000–120,000 km depending on use). Any cracking, crumbling or missing sections means it’s time to replace.

Can worn bump-stops cause a safety inspection issue?
Potentially. If a stopper is missing or badly degraded so the suspension can bottom out, it may attract defect attention or fail an inspection. Keeping bump-stops intact helps maintain safe suspension travel and reduces impact loads on other components.
