Parts for your 2016 Mitsubishi Outlander-Bump stops

2016 Mitsubishi Outlander bump-stops: what they do and when to replace them

Based on technical references, bump-stops are absolutely fitted to the 2016 Mitsubishi Outlander. The Mitsubishi Motors Service Manual for the GF/GP series (2016) identifies a jounce bumper (bump-stop) on the front MacPherson struts in the Front Suspension section, and a rear suspension bump stopper in the Rear Suspension section. Mitsubishi’s electronic parts catalogue (ASA/EPC) also lists these components for this model year, and major aftermarket catalogues (e.g., KYB and Monroe) supply strut boot-and-bump-stop kits for 2013–2018 Outlander, confirming their use.

On this Outlander, the front bump-stop sits under the strut’s dust boot on the damper rod. It’s a dense microcellular foam that progressively cushions the last part of suspension travel, stopping the strut from slamming into itself on big hits. Down the back, the vehicle uses a separate bump-stop for the rear suspension that prevents the arm and body from making hard contact when fully compressed.

Purpose-wise, bump-stops protect the shocks and struts from bottoming, keep the geometry in check during heavy loads or off-road corrugations, and knock back noise, vibration and harshness. They also help keep tyres happier by preventing sudden toe/camber changes at full compression, which is handy when towing or with a boot full of camping gear.

As for servicing a 2016 Outlander, they’re worth a look any time the suspension is inspected or when shocks/struts are replaced. Front bump-stops live inside the boot, so the strut needs to come out to replace them, that’s why they’re commonly renewed as part of a strut job. Rear bump-stops are easier to sight and swap if they’re cracked or perished.

• Inspect every 50,000–60,000 km or if there’s a heavy “thud” on big bumps.
• Replace in pairs (fronts together, rears together) with OE-quality foam bumpers.
• Check dust boots at the same time, a torn boot accelerates bump-stop wear.
• After front strut work, get a wheel alignment to keep tyre wear even.

Typical signs they’re due: visible cracking or chunks missing from the foam, noisy bottoming over speed humps, or new leaks from a shock that’s been hammered. Fresh bump-stops are a cheap bit of insurance that keeps the Outlander riding quietly and the dampers living longer.

FAQs

How often should bump-stops be replaced on a 2016 Outlander?
There’s no fixed interval, but a good rule is to inspect them every 50,000–60,000 km and whenever shocks or struts are replaced. If the foam is perished, split, or compressed flat, it’s time. Most workshops will bundle new bump-stops with front strut replacements because the strut has to come out anyway.

What are the symptoms of worn or failed bump-stops?
Common giveaways include a hard “clunk” or “thud” on speed humps or potholes, a torn or collapsed dust boot, or accelerated shock wear and leaking after repeated bottoming. You might also notice harsher ride quality when loaded or towing.

Can bump-stops be upgraded for towing or rough roads?
Yes. Some owners opt for heavy-duty or progressive-rate bump-stops. They can improve control at full compression and help when carrying loads, but may make the last bit of travel firmer. Sticking with OE-style microcellular foam keeps the factory ride feel, going stiffer is a trade-off.
