Parts for your 2008 Subaru Exiga-Rack boots

2008 Subaru Exiga rack boots: purpose, care and replacement

Per the Subaru Exiga YA-series factory service manual and the Subaru FAST electronic parts catalogue, the 2008 Subaru Exiga uses a rack-and-pinion steering gear fitted with rubber bellows on both sides—commonly called rack boots, steering rack boots, or gaiters. That makes rack boots absolutely relevant to this model.

On the Exiga, the rack boots seal out grit, water and road grime, and help keep grease where it belongs around the inner tie rod and rack ends. They also allow the steering to move freely while protecting the delicate rack seals. If a boot splits, contaminants can chew out the inner tie rod and rack bushes, and hydraulic fluid from a leaking rack seal can pool inside the boot—both of which are red flags at WOF/roadworthy time and can snowball into an expensive steering rack replacement.

Good workshops treat rack boots as a routine inspection item at every service. For an Exiga doing typical Aussie or Kiwi kilometres, the check is simple: look for cracks, perishing, loose clamps, or any oily residue around the boot ends. A clean, supple boot with tight clamps is what you want. If there’s fluid inside the boot, that points to an internal rack seal leak rather than just a perished boot.

• Tell-tale signs: visible splits or weeping, dirt packed inside the bellows, vague steering feel, or a clunk over bumps.
• Best practice: replace boots in pairs if age-related cracking is present, and always fit quality clamps.

Replacing rack boots on the 2008 Exiga is straightforward for a trained tech: wheel off, outer tie-rod end off, old boot and clamps off, clean and inspect the inner tie rod for play, slide on the new boot, and clamp it correctly (keeping any breather path clear). Because toe settings can change when the tie-rod end is disturbed, a wheel alignment check is recommended straight after. Sticking with OEM-spec or quality aftermarket EPDM boots helps them resist ozone, heat and road splash for longer life.

There’s no fixed replacement interval—climate and use matter—but once a boot shows cracking or has gone soft and sticky, it’s time. Sorting a $30–$80 boot now is far cheaper than a steering rack down the track, and it keeps the Exiga tight, quiet and safe on Aussie and NZ roads.

Popular questions

How often should rack boots be replaced on a 2008 Subaru Exiga?
There’s no set kilometre interval. Have them inspected at every service. In New Zealand and Australia, many fail from age and heat around the 8–12 year mark. Replace at the first signs of cracking, splitting, or loose clamps, or if contamination is found inside.

Do you need a wheel alignment after replacing Exiga rack boots?
Yes—at minimum, have the alignment checked. Removing the outer tie-rod end to change the boot usually shifts toe. A quick alignment protects tyres and keeps the Exiga tracking straight.

Is it safe to drive with a split rack boot?
It’s not ideal. Short, gentle trips to a workshop are usually fine, but dirt and water can quickly damage the inner tie rod and rack seals. A split boot can also trigger a WOF/roadworthy fail, so it’s best sorted promptly.
