Parts for your 2012 Subaru Forester-Bump stops

2012 Subaru Forester bump-stops — what they do and how to look after them

Bump-stops are absolutely fitted to the 2012 Subaru Forester and very much relevant. Technical sources that confirm this include the Subaru Service Manual for the SH-series Forester (2012 MY), which shows a “Bump Stopper” (jounce bumper) as part of both the front strut and rear shock assemblies in the Front Suspension (FS) and Rear Suspension (RS) sections. The Subaru FAST electronic parts catalogue for SH Forester also lists dedicated “BUMP STOPPER” items for front and rear, reinforcing that they’re standard equipment.

On this Forester, bump-stops act like soft cushions at the end of the suspension’s travel. They prevent the strut or shock from bottoming out hard against its internal limits, help control extreme body movement, and protect mounts, springs, and dampers from impact damage. They also shape how the suspension feels at the edge of travel—good bump-stops add a progressive, controlled ramp-up so the Forester stays composed over whoops, potholes, and heavy loads.

Because they live inside the dust boots or on the shock body, bump-stops cop a tough life: heat, road grime, UV, and repeated compression. Over time, the microcellular foam or polyurethane can crack, harden, or crumble. When that happens, the Forester can feel harsh over big hits, make a dull thud on speed humps, and place extra stress on struts, top mounts, and even tyres.

Servicing advice for a 2012 Forester’s bump-stops is straightforward: inspect them whenever the wheels are off, especially during brake, tyre, or shock work. If the dust boot is torn, check the bump-stop closely—grit accelerates wear. Replace in axle pairs to keep the handling balanced, and match the part to the car’s setup (factory height, towbar loads, or lift). When fitting new struts or springs, it’s smart money to refresh bump-stops and boots at the same time, as access is already sorted.

• Look for perishing, splits, or chunks missing from the foam.
• If the suspension is bottoming out, consider firmer or longer bump-stops suited to load or lift.
• Re-torque strut/shock hardware with the vehicle at ride height to avoid bushing preload.

As a rule of thumb, have the bump-stops checked every 20,000–40,000 km or whenever there’s a knock over big bumps. Owners who tow, carry gear, or tackle corrugations should keep an extra eye on them.

Popular questions about 2012 Subaru Forester bump-stops

How long do bump-stops last on a 2012 Forester?
They often last as long as the shocks, but climate and use matter. Many owners see them still serviceable past 100,000 km, while vehicles that tow, run rough roads, or see lots of UV can need them sooner. If the dust boot is split or there’s a new harsh thud on big hits, it’s time to inspect and likely replace.

Do lift kits or heavy loads mean different bump-stops?
Yes. A suspension lift or frequent towing/loads can call for longer or more progressive bump-stops to maintain compression control and protect components. Pair the bump-stop choice with spring and shock rates, and get an alignment after any suspension height change.

Can worn bump-stops affect a WOF or roadworthy?
They can be flagged if missing, badly perished, or clearly compromising suspension control. Even if it passes, a damaged bump-stop is a false economy—replacement is inexpensive protection for pricier parts like struts, mounts, and tyres.
