Parts for your 2015 Subaru Exiga-Rack boots

2015 Subaru Exiga rack-boots: what they do and when to replace them

Yes, the 2015 Subaru Exiga is fitted with steering rack boots. This is confirmed by Subaru’s YA-series Exiga Service Manual (Steering: Rack and Pinion – Boot inspection/replacement procedures) and by the Subaru FAST electronic parts catalogue for the 2015 Exiga, which lists a “Boot – Steering Gear” for the model. These technical sources show the Exiga uses a rack-and-pinion steering gear with a flexible boot (gaiter) on each side to protect the inner tie rods and rack seals.

On a 2015 Subaru Exiga, the rack-boots do an unglamorous but vital job. They act as dust and moisture shields for the inner tie rod joints and the ends of the steering rack. By sealing out grit and road splash, they help the grease inside stay clean and they prevent premature wear of the rack and inner joints. On hydraulic power-steering versions, the boots also help keep any weeps contained so a tech can spot a failing rack seal before it turns into a bigger drama.

As part of regular servicing, it’s smart to have the rack-boots inspected every 10,000–15,000 km, or at each service. If the boots are perished, split, loose on their seats, or holding fluid, they should be replaced promptly. Driving with torn boots lets water and grit chew out the inner tie rod and can fast-track wear in the rack itself, which gets expensive quickly.

Replacing a rack-boot on an Exiga is a straightforward workshop job: the technician removes the tie rod end, slides off the old boot, cleans the area, fits the new boot with proper stainless clamps, and reinstalls the tie rod end to the recorded measurement. A wheel alignment is recommended afterward to keep the steering centred and protect tyre wear. Using genuine or quality OEM-spec boots and proper crimp clamps (not cable ties) is the go for a lasting seal.

• What to watch for: cracks, oil inside the boot, loose or missing clamps, and knocking or notchy steering.
• Good practice: replace boots in pairs if they’re the same age, check inner tie rods while you’re there, and re-grease as specified by the service manual.
• Typical time: around 0.5–1.0 hour per side plus alignment.

Kept in good nick, fresh rack-boots help the Exiga’s steering stay precise and quiet, and they save the rack from avoidable wear down the track.

FAQs

Does a 2015 Subaru Exiga actually have rack-boots?

It does. Subaru’s service manual for the YA-series Exiga and the official parts catalogue both list steering rack boots (gaiters) fitted on each side of the rack to protect the inner tie rods and seals.

How often should rack-boots be checked or replaced on a 2015 Exiga?

Have them inspected at every service (about every 10,000–15,000 km). Replace them if they’re cracked, perished, loose on the rack or tie rod, or if there’s fluid inside the boot. A wheel alignment is recommended after replacement.

Is it okay to drive with a torn rack-boot?

Best not. A torn boot lets water and grit in, which can damage the inner tie rod and the steering rack seals. That can turn a cheap boot job into a pricey rack replacement, so fixing it early is the smarter move.
