Parts for your 2019 Mitsubishi Asx-Bump stops

2019 Mitsubishi ASX bump-stops: purpose, checks and replacement

Based on technical references — including the Mitsubishi Motors ASX/RVR/Outlander Sport Service Manual (2010–2020, Group 33A/33B: Front and Rear Suspension), the Mitsubishi ASA electronic parts catalogue for GA-series ASX models, and major suspension catalogues from KYB and Monroe — the 2019 Mitsubishi ASX is fitted with bump-stops. The front MacPherson struts use internal jounce bumpers (often integrated with the dust boot), and the rear suspension uses rubber bump stoppers mounted to control full-compression travel.

The bump-stops on a 2019 Mitsubishi ASX act like soft limiters for the suspension. When the car hits a nasty pothole, a speed hump too quickly, or runs loaded on corrugated back roads, the bump-stops take the sting out of the last bit of travel so the struts, springs, mounts and body don’t cop metal-to-metal hits. On the front, the jounce bumper slides on the strut shaft inside the boot, out back, the rear stopper cushions the arm or axle as it nears full bump. This protects the shock absorbers, keeps steering and alignment happier, and helps the tyres stay planted when things get rough.

Servicing-wise, they’re cheap insurance. Any time struts or rear shocks are replaced, the bump-stops and dust boots should be inspected closely and usually renewed — the foam or rubber can perish, split, go mushy from oil contamination, or simply be missing. A quick visual every 40,000–60,000 km (or during routine suspension checks) is smart. Red flags include harsh “thuds” on bigger hits, a sudden, jarring ride, torn boots, or signs the suspension is frequently bottoming out. If the ASX is carrying extra gear, towing, or riding lower than it used to, that can force the car onto the bump-stops more often, make sure springs and loads are sorted, not just the stoppers.

Replacement is straightforward for a pro and doable for experienced DIYers with the right gear. Front bump-stops require strut removal and a proper spring compressor, torque specs and assembly order from the Mitsubishi workshop manual must be followed, and a wheel alignment is recommended after front strut work. Rear stoppers are typically easier but still demand safe support of the vehicle. Replace in pairs, choose quality OE or equivalent parts, and double-check orientation so the bumper engages smoothly. For Aussie and Kiwi roads — from urban speed humps to unsealed stretches — healthy bump-stops help the ASX ride nicer and keep expensive suspension bits from wearing out early.

• Inspect bump-stops with every shock/strut service.
• Replace when cracked, oil-soaked, deformed, or missing.
• Align the front end after strut work.

Popular questions about 2019 Mitsubishi ASX bump-stops

Does the 2019 Mitsubishi ASX actually have bump-stops?
Yes. The Mitsubishi Service Manual for ASX/RVR/Outlander Sport (2010–2020) details a jounce bumper in the front strut assembly and a rear bump stopper. The Mitsubishi ASA parts catalogue and aftermarket suspension catalogues (e.g., KYB, Monroe) also list these components for 2019 models.

When should bump-stops be replaced on a 2019 ASX?
They’re typically replaced whenever struts or rear shocks are changed, or if inspection shows cracking, tearing, oil contamination, or missing pieces. If the car feels harsh over bigger bumps or “bangs” at full compression, it’s time to check them. A 40,000–60,000 km inspection interval works well alongside routine suspension checks.

Can worn bump-stops damage other components?
They can. Without effective bump-stops, the suspension can bottom out hard, which accelerates wear on strut mounts, shocks, control arm bushes and can upset tyre contact. Repeated bottoming can also nudge alignment out of spec, hurting tyre life and steering feel.
