Parts for your 2010 Mitsubishi Outlander-Bump stops

2010 Mitsubishi Outlander bump-stops

Yes, the 2010 Mitsubishi Outlander is fitted with bump-stops (also called jounce bumpers). This is documented in Mitsubishi’s factory service information: the Front Suspension (Group 33A) details a strut-mounted bump rubber, and the Rear Suspension (Group 34A) specifies a rear bump stopper. The Mitsubishi ASA electronic parts catalogue for CW-series Outlander models likewise lists front and rear bump rubbers/stopper components. Major damper catalogues (e.g., KYB and Monroe) also specify boot-and-bump-stop kits for this model range. Put simply, they’re part of the design and matter for how the Outlander rides and lasts.

On a 2010 Outlander, the bump-stops act as the final, progressive cushion when the suspension compresses hard—think big speed humps, corrugations, towing loads, or a fully packed family trip. Up front, they sit on the MacPherson strut shaft under the dust boot, out back, the multi-link setup uses dedicated stoppers at the damper or chassis. Their job is to prevent metal-to-metal contact, protect the shocks and struts from bottoming out, and smooth the hit so the cabin doesn’t cop a harsh thud. That little foam or microcellular polyurethane “buffer” also helps keep tyres happier by controlling extreme travel, which maintains alignment angles better over big bumps.

Because bump-stops live a hard life and age with heat, UV and road grime, they can crack, crumble, or go mushy. When that happens, the Outlander can start to bottom out under load, make a dull knock over big hits, or show polished “witness marks” where components touch. Best practice is to inspect them whenever shocks/struts are serviced and at roughly 40,000–60,000 kilometres, or during a WOF/RWC check. Many technicians replace bump-stops as a kit with new dust boots when fitting shocks or struts, since the strut has to come out anyway and the parts are relatively inexpensive.

Replacement is straightforward for a pro: fronts require strut removal and a spring compressor, rears vary but are typically simpler. Always replace in pairs on an axle, use OE-style microcellular polyurethane stoppers, and torque mounts to spec. After front strut removal, a wheel alignment is recommended. If the Outlander is used for towing, rough roads or has a small lift, selecting stoppers with the correct length and progressive rate helps maintain safe jounce clearance without killing ride or articulation. It’s a small part that quietly saves shocks, mounts and bushings, and keeps the Outlander feeling tidy on Aussie and Kiwi roads.

Popular questions

How do you know the Outlander’s bump-stops need replacing?

Look for cracking or crumbling foam under the dust boots, odd clunks on big compressions, or signs the suspension is bottoming (shiny contact marks). If you’re already replacing shocks or struts, inspect the stoppers at the same time—age and heat often get to them before the dampers do.

Can you drive with damaged bump-stops?

You can, but it’s not wise. Without a healthy final cushion, the suspension can bottom out, stressing shocks, mounts and control arm bushes, and making the ride harsher. Replacing them is cheap insurance against bigger suspension repairs.

Do you need an alignment after replacing bump-stops?

If the front struts are removed to access the bump-stops, yes—book a wheel alignment. Rear-only stopper swaps usually don’t disturb alignment, but if any rear arms or subframe bolts are loosened, an alignment check is smart.
