Parts for your 2015 Subaru Forester-Rack boots

2015 Subaru Forester rack boots: what they do and how to look after them

Yes, the 2015 Subaru Forester uses rack boots. Technical references that confirm this include the Subaru Forester (SJ, 2014–2018) Service Manual’s Steering section, which illustrates a rack-and-pinion assembly with bellows-type steering gear boots on both ends, and the Subaru dealer parts catalog that lists a “Boot – Steering Gear” for 2015 Forester variants. Major aftermarket fitment guides also supply rack-boot kits specifically for this model. Even on Foresters with electric power steering, the rack still uses protective boots to shield the inner tie rods and rack seals.

On a 2015 Forester, rack boots (also called steering rack bellows) are flexible rubber sleeves that keep water, grit, and road grime out of the rack-and-pinion and inner tie rods. They also help retain the special grease around the inner ball joints. If a boot splits or comes loose, contaminants can chew out the inner tie rod and rack seals, leading to play at the wheel, steering noise, and—on hydraulic systems—fluid leaks. Left too long, it can mean a pricey rack replacement.

As part of regular servicing, a quick visual under the bonnet and on a hoist goes a long way. They should be inspected at every service or at least every 10,000–15,000 km, and any time there’s a knock in the steering, uneven tyre wear, or a WOF/RWC check coming up.

• What to look for: perished or cracked rubber, grease flung out near the clamps, a boot that’s slipped off its groove, or moisture/road grime inside the boot.
• Replacement tips: always replace in pairs if one is gone, and fit new clamps. If the inner tie rod has play or corrosion, sort that at the same time. After any steering work, a wheel alignment is a must.
• Prevention: keep an eye on torn splash shields and undertrays that let extra muck into the area, and wash off heavy mud after off-road use. EPS models still need this love—boots protect the mechanicals regardless of power assist type.

Many owners find boots last years in normal Aussie and Kiwi conditions, but vehicles used on gravel or beach tracks may need them sooner. Replacing a boot is cheap insurance compared to a steering rack.

Popular questions about 2015 Subaru Forester rack boots

How often should rack boots be replaced?
There’s no fixed interval, they’re replaced on condition. Have them inspected at each service. If the rubber is cracked, loose, or contaminated inside, replace promptly to protect the rack and inner tie rods.

What are the signs a rack boot has failed?
Visible splits, grease thrown around the boot area, a boot off its seat, or dirt and moisture inside the bellows. You might also notice steering play or uneven tyre wear if the inner tie rod has started to wear.

Will a torn rack boot fail a WOF/RWC?
Often, yes. A damaged or unsecured steering boot can be flagged in New Zealand WOF and Australian roadworthy checks because it compromises steering integrity and can lead to rapid wear.
