Parts for your 2016 Mitsubishi Asx-Bump stops

2016 Mitsubishi ASX bump-stops

Based on technical sources, bump-stops are fitted to the 2016 Mitsubishi ASX. The Mitsubishi Motors 2016 ASX/RVR/Outlander Sport workshop manual identifies a “bump stopper” (jounce bumper) on each front MacPherson strut and body-mounted jounce bumpers for the rear suspension. The Mitsubishi ASA electronic parts catalogue lists these components, and major damper catalogues for this model note integrated bump-stop and dust-boot assemblies. So, bump-stops are relevant to servicing a 2016 ASX.

The ASX’s bump-stops do more than just stop a clang on big hits. They’re a compact bit of microcellular foam that adds a progressive spring rate right at the end of suspension travel. That means when the car’s loaded up for a weekend away or hits a nasty pothole, the suspension can compress deeply without metal-to-metal contact. The result is a calmer cabin, better control over rough roads, and less stress on shocks, springs, and mounts.

On the front, the jounce bumper lives on the strut shaft under the dust boot. Out back, the ASX uses body-mounted bump-stops that the suspension contacts at full compression. Over time, heat, age, and road grime can make the foam crack or crumble. Oil from a weeping strut also attacks the material, so if a front damper is leaking, expect the bump-stop and boot to be past their best too.

As part of routine servicing, it’s smart to have a look every 40–60,000 kilometres or whenever the front struts or rear springs are out. If the car is driven on corrugations, unsealed roads, or regularly carries heavy loads, check them more often. When replacing front shocks, treat bump-stops and boots as consumables—many quality kits bundle them together. For lowered springs, make sure the bump-stop length and rate suit the reduced travel to avoid riding the stops.

• Signs they’re due: harsh “bottoming” over speed humps, dull thuds on big compressions, or visible cracking/crumbing when the boot is lifted.
• Fitment tips: seat the bump-stop correctly on the strut shaft, don’t grease the foam, and torque suspension bushes at normal ride height. A wheel alignment is recommended after front strut removal.

Look after the bump-stops and they’ll quietly protect the ASX’s ride, handling, and tyres for the long haul.

Popular questions about 2016 Mitsubishi ASX bump-stops

How long do ASX bump-stops typically last?
They often last as long as the dampers—anywhere from about 80,000 to 150,000 kilometres. Heat, age, and rough-road use shorten their life. If shocks are being replaced, it’s wise to renew bump-stops and boots at the same time.

Is it okay to drive with damaged or missing bump-stops?
Not ideal. Without them, the suspension can bottom out, risking damage to shocks, springs, mounts, and even tyres. It also ramps up noise and can affect roadworthiness. Best to sort them promptly.

Do bump-stop replacements require a wheel alignment?
If the front struts are removed to access the bump-stops, get an alignment. For rear body-mounted jounce bumpers swapped without disturbing alignment points, it’s usually not required.
