Parts for your 2009 Mitsubishi Outlander-Bump stops

2009 Mitsubishi Outlander bump-stops: what they do and when to replace

Yes, the 2009 Mitsubishi Outlander is fitted with bump-stops. Technical sources confirm this: the Mitsubishi Outlander (CW) Service Manual (2007–2010) lists a jounce bumper/bump stopper within the front MacPherson strut assembly (Group 33A – Front Suspension), and a bound stopper/bump stop on the rear shock absorber in the rear multi-link setup (Group 34A – Rear Suspension). Mitsubishi’s ASA electronic parts catalogue for CW5W/CW6W also shows front strut jounce bumpers and rear shock stoppers, and major shock brands’ catalogues provide matching bump-stop and dust-boot kits for 2007–2012 Outlander models.

On the 2009 Outlander, bump-stops act like a final safety cushion for the suspension. When you hit a big pothole, carry a heavy load, or go over a speed hump a bit hot, they step in before the suspension bottoms out, stopping metal-to-metal contact. That protects the struts/shocks, top mounts, springs and even the body, and helps the car keep its line instead of getting skittish. They’re usually made of microcellular foam or rubber and work as a progressive mini-spring, adding rate only when you need it.

Because they live inside the front strut boots and on the rear damper rods, they cop heat, road grime and shock loads. Over time they can perish, crack, compress permanently, or get chewed up if a dust boot splits. If they’re damaged, you’ll often feel a harsh “bang” on big hits, notice extra clunks, or see the car bottom out more easily under load or towing.

Good practice on a 2009 Outlander is to inspect bump-stops any time the front struts or rear shocks are off the car, and during routine servicing at least annually or every 20,000 km. Replace them if they’re cracked, oil-soaked, excessively compressed, or if the matching dust boots are torn. It’s smart to fit new bump-stops and boots whenever you replace struts/shocks, or if you’ve changed ride height with lift/lowering springs. Go for quality OEM-equivalent foam bumpers, they’re tuned to work with the Outlander’s suspension travel and rates.

DIY? Use a proper spring compressor for front struts and follow the service manual for disassembly order and torque specs. If you tow, tackle corrugations, or load up the family and gear often, keep an extra eye on them—fresh bump-stops are cheap insurance against blown shocks, bent mounts and scalloped tyres.

• Watch for: harsh bottoming, new clunks over big bumps, torn boots, visible cracks in bump-stops.
• Replace with: matched bump-stop and dust-boot kits, check top mounts and bearings while you’re there.
• Service tip: inspect at each suspension service, replace with struts/shocks or at first sign of deterioration.

Popular questions about 2009 Mitsubishi Outlander bump-stops

Where are the bump-stops located on a 2009 Outlander?
They’re built into the suspension. Up front, the bump-stop (jounce bumper) sits on the strut shaft under the dust boot. In the rear multi-link, the bump-stop is on the shock absorber assembly as the bound stopper. You won’t usually see them until the strut/shock is removed.

How often should bump-stops be replaced?
There’s no fixed interval. Inspect them at each service or whenever struts/shocks are out. Replace if they’re cracked, perished, oil-soaked, or if you’re fitting new dampers or changing ride height. Many techs replace them proactively with every strut/shock change.

Is it safe to drive with damaged bump-stops?
Short trips might be fine, but it’s not ideal. Without a healthy bump-stop, hard hits can bottom the suspension, risking strut/shock damage, bent mounts, and accelerated tyre wear. If you’re hearing harsh knocks on big bumps, get them checked soon.
