Parts for your 2007 Mitsubishi Outlander-Bump stops

2007 Mitsubishi Outlander bump-stops

Based on technical sources, bump-stops are absolutely fitted to the 2007 Mitsubishi Outlander. The Mitsubishi Outlander 2007 Factory Service Manual identifies a “bump stopper/jounce bumper” on the MacPherson strut assembly in Group 33A (Front Suspension) and shows a jounce bumper integrated with the rear shock assembly in Group 34A (Rear Suspension). The Mitsubishi ASA Electronic Parts Catalogue for CW5W/CW6W model codes also lists front “stopper/bump stopper” and rear “shock absorber bumper” for 2007 build vehicles. So, on this Outlander, bump-stops are relevant and part of the suspension by design.

On a 2007 Mitsubishi Outlander, the bump-stops (often called jounce bumpers) act like a final cushion when the suspension runs out of travel. They’re usually made from microcellular foam or rubber and sit on the strut shaft up front and on the rear shock/arm at the back. When the wagon hits a big pothole, corrugations on a country road, or carries a boot full of gear, the bump-stops progressively take load to prevent metal-to-metal contact. That protects struts, shocks, springs, top mounts, and even the body shell from harsh bottoming, while keeping the ride quieter and the tyres planted.

As part of routine servicing, it’s smart to eyeball the bump-stops whenever the struts or shocks are inspected—ideally every 40,000–60,000 km, or sooner if the Outlander tows, sees gravel roads, or has aftermarket lowering springs. They should look intact, springy, and evenly shaped. Replace them if they’re cracked, oil-soaked, crumbling, split, collapsed, or missing. Because they work hand-in-hand with dust boots, replace torn boots at the same time to stop grit from chewing out the new parts and the damper seals.

• Always replace bump-stops in axle pairs for consistent handling and ride height at the limits.
• Choose quality OE-equivalent foam or polyurethane units matched to the Outlander’s damper stroke, incorrect height can cause premature bottoming or a harsh ride.
• When fitting, seat the stop correctly on the strut/shock and ensure the protective boot is clipped in place—no grease needed.
• After front strut work, a wheel alignment is recommended to keep tyre wear even.

If the Outlander thuds over speed bumps, bottoms out with a bang, or feels skittish when loaded, the bump-stops might be past it. Fresh ones restore that last line of defence, keeping the family SUV comfortable and composed across Aussie and Kiwi roads.

How long do bump-stops last on a 2007 Outlander?

Typically they’ll go 8–12 years, but climate, road grime, and leaking shocks can shorten their life. If the vehicle does lots of kilometres on rough roads or tows regularly, inspect more often and expect earlier replacement.

What are the signs the bump-stops need replacing?

Look for cracking, chunks missing, or a collapsed shape. From the driver’s seat, frequent bottoming-out thuds, a sharper-than-normal impact on big hits, or torn dust boots are common clues.

Can worn bump-stops affect a WOF or RWC?

They can. If the stops are missing or perished to the point the suspension can strike metal-to-metal, an inspector may fail the vehicle on safety grounds for both NZ WOF and AU RWC checks.
