Parts for your 2013 Subaru Legacy-Rack boots

2013 Subaru Legacy rack-boots: what they do and when to replace them

Technical sources confirm the 2013 Subaru Legacy is fitted with rack boots. Subaru’s 2013 Legacy/Outback Service Manual (Steering section) specifies bellows-type boots on the rack-and-pinion to protect the inner tie-rods and rack bar. Subaru’s official electronic parts catalogue (FAST) lists “Boot – Steering Gear” and the associated clamps for this model, and mainstream workshop data (e.g., ALLDATA/Mitchell1) includes routine inspection of steering gear boots for the 2013 Legacy. So yes—rack boots are relevant and used on this vehicle.

On a 2013 Subaru Legacy, rack boots are the flexible bellows on either end of the steering rack. Their main job is to keep grit, water, and road grime out of the inner tie-rod joints and the rack bar, while keeping grease where it needs to be. Whether the car runs electric power steering on a 2.5i or hydraulic assist on some variants, those bellows are vital for long rack life, smooth steering feel, and consistent alignment.

Cracked or perished boots let contaminants in, which chews out inner tie-rods and the rack seals. On hydraulic systems you might also spot fluid weeping from a torn boot. Left too long, the damage can escalate from a simple boot swap to inner tie-rod or full rack replacement—costly and avoidable.

As part of normal servicing, it’s smart to inspect the rack boots every service or at least every 10,000–15,000 kilometres. Look for splits, oil or grease residue on the outside, loose or missing clamps, and any signs the boot is rubbing or twisted at full lock. If one side has failed, it’s often best practice to do both sides together.

Replacement is straightforward for a trained tech and pairs nicely with inner tie-rod checks. A few pro tips:

• Use genuine or OE-quality EPDM boots and new clamps—reusing old bands can lead to leaks.
• Set the steering rack at centre and avoid twisting the bellows during install.
• Lightly grease the inner pleats so the boot flexes cleanly.
• Torque tie-rod locknuts to spec, then book a wheel alignment—any tie-rod disturbance can shift toe.

Drivers might notice tell-tales like a knocking over bumps, vague steering, or uneven tyre wear when boots or inner tie-rods are on the way out. Catching a split boot early is a quick, affordable fix that protects the Legacy’s steering gear for the long haul.

Are rack boots the same on all 2013 Legacy variants?

They serve the same purpose across the range, but part numbers and clamp styles can differ between engines and power-steering types. Always match by VIN to get the right boots and hardware.

Do I need a wheel alignment after replacing rack boots?

Yes, if the tie-rod ends are disturbed. Most boot replacements involve removing at least the outer tie-rod, so a post-job alignment is recommended to keep tyre wear even and the steering tracking straight.

What are the signs a rack boot has failed?

Common signs include visible splits or perishing, grease slung on the control arm, dampness or fluid inside the boot on hydraulic systems, new knocks over bumps, or accelerated inner tie-rod wear and uneven tyres.
