Parts for your 2018 Subaru Xv-Rack boots

2018 Subaru XV rack-boots

Rack-boots are fitted to the 2018 Subaru XV. This is supported by Subaru’s factory Service Manual for the 2018 MY XV/Impreza platform (Steering section: Steering Gearbox/Linkage – Rack Boot inspection and replacement procedures) and the Subaru Electronic Parts Catalogue, which lists a Boot – Steering Gear (commonly referenced as p/n 34137FL000) for the 2018 XV. Those official technical sources confirm the vehicle uses protective rack boots on its electric power steering rack.

On the 2018 Subaru XV, the rack-boots (also called steering rack gaiters) seal the ends of the rack-and-pinion housing and cover the inner tie rods. Their job is simple but crucial: keep dust, water, and road grit out, and keep grease in. Because the XV runs an electric power steering rack (no hydraulic fluid), moisture or grit entering past a torn boot can quickly pit the rack bar and inner tie rod sockets, leading to stiffness, free play, or noisy steering. Left alone, contamination can escalate repair costs and may trigger a WOF/roadworthy fail in NZ or Australia.

As part of routine servicing, it’s smart to inspect the rack-boots every visit (typically every 10,000–15,000 km or 6–12 months), and more often if the XV sees gravel roads, beach launches, or muddy trails. Signs it’s time to act include visible splits or perishing rubber, missing or loose clamps, or grease flung onto the crossmember. Steering that feels notchy after rain, or a faint knock on rough roads, can also hint at contamination inside the boot.

When replacement’s needed, the process involves removing the tie-rod end, sliding off the old boot, cleaning and checking the rack and inner tie rod, then fitting a quality boot with new bands. Using the correct clamp type (not cable ties) and the specified grease is important, and care is taken not to twist or pinch the new boot. Because the tie-rod end is disturbed, a wheel alignment is recommended straight after. Many workshops will do one side in under an hour, but allow extra time for alignment.

Genuine Subaru boots (as referenced in the EPC) or an OE-quality equivalent are the go-to. For owners who regularly tour corrugated roads or head off the beaten track, asking the workshop to give the boots an extra look each service is cheap insurance for the steering gear and tyres.

• Inspect rack-boots each service, sooner after off-road or floodwater exposure.
• Replace at first sign of cracking, tearing, or loose bands.
• Always finish with a proper wheel alignment.

Popular questions about 2018 Subaru XV rack-boots

How long do rack-boots usually last on a 2018 XV?
With normal on-road use, they can last many years, often 5–10. Heat, UV, and rough surfaces shorten that. An annual service inspection is the best way to catch ageing before it causes damage.

Is it safe to drive with a torn rack-boot?
It’ll usually drive, but every kilometre risks water and grit getting into the rack, which can chew out the inner tie rod and rack teeth. It can also affect roadworthy/WOF. It’s best to organise replacement promptly.

Do rack-boots affect wheel alignment?
The boots themselves don’t set alignment, but replacing one normally means removing the tie-rod end. That disturbs toe, so a wheel alignment is recommended straight after the job.
