Parts for your 2008 Subaru Exiga-Bump stops

2008 Subaru Exiga bump-stops: what they do and how to look after them

Yes, the 2008 Subaru Exiga does use bump-stops. Technical references such as the Subaru Exiga (YA) Service Manual – Suspension (Front and Rear) and the Subaru FAST electronic parts catalogue list a “bump rubber/jounce bumper” as part of each damper assembly. The Exiga’s front MacPherson struts and rear shock/damper units both rely on these bump-stops to protect the suspension and body from harsh bottoming-out.

On this model, the bump-stop is essentially a compact, progressive foam buffer that acts like a secondary spring near the end of suspension travel. When the Exiga hits a big pothole, speed hump, or carries extra weight, the bump-stop cushions the last bit of movement so the damper and mounts don’t smash into a hard stop. That protects the strut rods and seals, helps keep alignment steady under heavy load, and takes the sting out of big hits, reducing noise and vibration inside the cabin.

They’re usually made from microcellular polyurethane foam and live under the dust boot on the damper rod. Over time they can harden, crack, or crumble—especially on higher-kilometre cars, those that carry family loads, or vehicles running lowered springs. Typical signs the Exiga’s bump-stops need attention include a sharp, harsh thud on big compressions, torn dust boots revealing crumbly foam, or the car feeling like it “hits the bump” too early after lowering.

Best practice is to inspect the bump-stops whenever the shocks or struts are serviced, and to replace them when fitting new dampers or springs. They’re inexpensive, but they play a crucial role in ride quality and component longevity. Keep the dust boots intact to protect the foam, avoid petroleum-based cleaners around the rubber/foam, and follow the Subaru service manual for correct assembly order and torque settings. If the Exiga is lowered, consider a shorter or firmer progressive bump-stop to preserve bump travel. For towing or heavy family duty, ensuring fresh bump-stops and sound top mounts helps the rear stay composed and protects the tyres and suspension.

• Check at each service or WOF: dust boots intact, no perished foam, no metal-to-metal bottoming marks.
• Replace whenever dampers are renewed, or if lowering/raising ride height.
• Re-seat spring isolators and mounts properly to prevent squeaks and uneven tyre wear.

Popular questions

How long do bump-stops last on a 2008 Subaru Exiga?
Typically they’ll last as long as the original dampers, but age, kilometres, and climate matter. After 8–12 years many factory bump-stops start to harden or crack. It’s smart to replace them when doing shocks/struts, or sooner if the dust boots are torn and the foam looks shabby.

Can the Exiga be driven with damaged bump-stops?
It’ll still drive, but it’s not ideal. Without a healthy bump-stop, the suspension can bottom out hard, risking damage to strut seals, top mounts, and even causing abnormal tyre contact on big hits. Expect harsher impacts and more noise. Get them sorted promptly to protect the rest of the suspension.

Do I need different bump-stops if I lower my Exiga or tow regularly?
If lowering, a shorter or firmer progressive bump-stop helps maintain usable bump travel and keeps the ride from feeling crashy. For towing and heavy loads, fresh OE-equivalent or load-appropriate bump-stops (and good dust boots) keep the rear controlled. Pair with suitable springs/dampers for best results.
