Parts for your 2014 Subaru Forester-Bump stops

2014 Subaru Forester bump-stops: what they do and when to replace them

Based on the 2014MY Subaru Forester (SJ) Factory Service Manual (Chassis: Suspension – Front Strut and Rear Shock sections) and Subaru’s official parts catalogues (FAST and dealer parts diagrams), the 2014 Forester is fitted with front and rear bump-stops (also called jounce bumpers). They sit on the damper rod inside the dust boot on MacPherson struts up front and on the rear shocks, and are a normal, serviceable component of the suspension.

On this Forester, bump-stops act like a final, progressive cushion at the end of suspension travel. When the wagon hits a big pothole, carries a heavy load, tows, or drops into a rut on a corrugated outback road, the bump-stop compresses to stop metal-on-metal contact inside the strut or between the axle and body. That protects the damper, strut top, control arm pivots and body mounts, and it also softens the thud that would otherwise make its way into the cabin. Because the foam or microcellular urethane is progressive, it effectively adds spring rate at the limit of travel, keeping handling tidy and helping the Forester stay composed when fully loaded.

As part of regular servicing, it’s smart to inspect the bump-stops whenever the wheels are off or the suspension is checked. Techs look for cracking, crumbling, missing chunks, permanent deformation, oil saturation from a leaking shock, or a split dust boot that’s let grit chew into the foam. If one side is shot, replacement in pairs is best practice to keep response balanced side‑to‑side. Given Aussie heat, UV, coastal air and Kiwi gravel roads, aged bump-stops can harden and then fail pretty quickly once they start to perish.

• Symptoms that point to tired bump-stops:
  • Harsh “bang” on big hits or when loaded up
  • New knocking after fitting heavier springs or a mild lift
  • Visible cracking or missing material when the strut boot is pulled back

Replacement usually means pulling the strut/shock and safely compressing the spring. A quality spring compressor and correct torque on reassembly are essential, so many owners leave it to a workshop. It pairs nicely with new dust boots and, if kilometre-age is up there, fresh strut mounts or dampers. After any front-end strut work, a wheel alignment is recommended. For daily driving and touring, OEM‑grade bump-stops are ideal, for lift kits or heavy‑duty springs, match the bump-stop height and density to the new travel so the Forester doesn’t bottom out or bind early.

How long do bump-stops last on a 2014 Subaru Forester?

They’re not a fixed-interval item, but many last 8–10 years. Heat, oil leaks, UV, and gravel rash can age them faster. A quick look at each service (or every 20,000 km) helps catch cracking or collapse before it causes harsh bottoming.

Can the Forester be driven with worn or missing bump-stops?

It’ll still drive, but it risks hard bottoming that can damage struts, top mounts and even tyres and alignment when loaded or off-road. If a bump-stop is crumbling or missing, it’s best to take it easy and get it replaced promptly.

Do lift kits or heavy-duty springs need different bump-stops?

Often, yes. Changes in ride height and travel can alter when the bump-stop engages. Matched bump-stops or spacers keep the jounce timing right, protect components, and preserve ride quality. Check the suspension kit’s guidance or ask a specialist.
