Parts for your 2017 Subaru Xv-Bump stops

2017 Subaru XV bump-stops: purpose, servicing and when to replace

Yes, the 2017 Subaru XV is fitted with bump-stops. Technical references that list them include the Subaru Factory Service Manual for the GP/GP7 XV (Front/Rear Suspension sections, where the “bump stopper” or jounce bumper is shown on the strut/shock assemblies), Subaru’s FAST electronic parts catalogue (which lists the front strut bumper and rear shock bumper for the XV/Impreza platform), and major shock manufacturers’ catalogues (KYB/Monroe) that supply strut boot kits with integrated jounce bumpers for this model.

On this XV, each front MacPherson strut runs a foam/rubber jounce bumper inside the dust boot, and the rear shock absorbers use a similar bumper. Their job is simple but vital: act as a progressive cushion right at the end of suspension travel, stopping metal-to-metal contact, preventing tyre-to-guard clashes, and protecting struts, top mounts and chassis from harsh bottoming. They also help keep alignment and handling tidy during heavy loads, corrugations and the odd bush track bash.

Because they’re made from microcellular foam or rubber, they age. Oil-soaked or UV-baked bump-stops harden, crack or crumble, which means harsher thumps over big hits and extra stress on shocks and mounts. Smart servicing on a 2017 XV includes checking bump-stops any time the wheels are off—ideally every 40–60,000 km or when you notice extra suspension noise. If you’re replacing struts or shocks, chuck in new bump-stops and dust boots at the same time, it’s cheap insurance and saves doubling up on labour.

Signs they’re due include: a dull thud on big compressions, visible splits or missing chunks on the bumper, foam that’s gone oily from a leaking strut, or frequent bottoming when loaded with camping gear. Coastal driving and unsealed roads around Aus and NZ can speed up deterioration, so regular inspections are worth it. Stick with quality OE or reputable aftermarket pieces, seat them in the boot correctly, and follow the workshop manual for reassembly—especially orientation and torque. Fronts need a spring compressor, rears are more straightforward, but still best handled with care.

Running without bump-stops isn’t a mod—it’s a fast track to bent mounts, damaged shocks and chewed tyres. Keep them healthy and the XV will ride quietly and cope better with rough stuff.

• Best practice: replace bump-stops and boots with every new strut/shock.
• Inspect at service intervals or before/after trips on corrugations.
• Consider travel management if the vehicle is lifted or frequently loaded.

Popular questions

Does the 2017 Subaru XV actually have bump-stops?
Yes. The Subaru Factory Service Manual for the GP/GP7 XV details a “bump stopper” on the front strut and rear shock assemblies, and Subaru’s FAST parts catalogue lists the corresponding jounce bumper parts. Aftermarket shock boot kits for this model also include the bump-stop, which confirms they’re part of the suspension by design.

Should bump-stops be replaced when fitting new shocks or struts?
Absolutely. They work hand-in-hand with the damper at full compression. If you’re already in there with a spring compressor, new bump-stops and dust boots add minimal cost and keep the fresh shocks protected. Old, oil-soaked or cracked bumpers can make a new suspension job feel harsh and noisy.

What if the XV is lifted—do the bump-stops need changing?
With a modest 20–30 mm lift, many owners keep OE-style bumpers, but it’s smart to check full-bump clearance. For heavier off-road use or bigger tyres, tuned or slightly longer bump-stops can control up-travel, protect guards and CVs, and keep handling predictable. Always verify travel and clearances after suspension mods.
