Parts for your 2016 Subaru Forester-Bump stops

2016 Subaru Forester bump-stops: what they do and when to replace them

Yes, the 2016 Subaru Forester (SJ) is fitted with bump-stops front and rear. Technical sources including the Subaru Service Manual (STIS) for the 2016 Forester chassis/suspension sections, the Subaru Genuine Parts catalogue for MY2016 Forester (SJ), and aftermarket catalogues from major shock makers (which include the jounce bumper in the strut boot kit) all list a “bump stopper/jounce bumper” for the front struts and a bumper on the rear shocks. So bump-stops are absolutely relevant on this model.

On this Forester, the bump-stop is a dense foam or micro-cellular urethane block that sits on the strut/shock shaft. Its job is to act as a progressive cushion at the end of suspension travel. When the vehicle hits a big pothole, loads up with gear, or runs out of suspension stroke on corrugations, the bump-stop takes the hit before metal-to-metal contact can happen. That protects the strut/shock internals, spring seats, upper mounts, and even the body. It also smooths out the last bit of travel so the cabin doesn’t cop a harsh thud.

Because they live inside the dust boot and constantly flex, bump-stops can perish, crack, or turn crumbly with age, UV, road grime, and leaked oil. On a 2016 Forester that’s seen a few hundred thousand kilometres or rough roads, it’s smart to inspect them whenever the struts/shocks are out—or during a suspension refresh. Many techs replace bump-stops and boots as a kit when fitting new dampers, as the labour overlaps and fresh stops help the new shocks last longer.

• Tell-tales of tired bump-stops: harsh bottoming over big hits, clunks at full compression, torn boots, or visible crumbling foam on tear-down.
• Service tip: if a strut or shock is weeping, assume the bump-stop and boot have copped oil and heat—replace the lot.
• Fitment notes: fronts are on the MacPherson strut, rears sit on the shock shaft. Front strut removal typically warrants a wheel alignment, rears usually don’t disturb camber/toe on this platform, but an alignment check is still good practice.

There’s no fixed interval for bump-stops, but a visual check at suspension service, or roughly every 40,000–60,000 km if you tour off‑road or tow, keeps the Forester riding sweet and the tyres planted.

FAQ: How often should 2016 Forester bump-stops be replaced?
There’s no set schedule. Inspect them whenever struts/shocks are replaced or removed. For vehicles seeing outback tracks, beach runs, or towing, plan a closer look every 40,000–60,000 km. If they’re cracked, oil-soaked, or compressed flat, replace them.

FAQ: What are the signs a bump-stop has failed?
Expect a hard thud on big hits, occasional clunks at full compression, and sometimes uneven suspension feel. A torn boot or crumbling foam found during service is a giveaway. Address it early to protect the dampers and mounts.

FAQ: Do you need an alignment after replacing bump-stops?
If the front struts are removed to access the bump-stops, a wheel alignment is recommended. Rear shock removal on the SJ Forester typically doesn’t alter alignment, but a post-job check is still sensible, especially if tyre wear has been uneven.
