Parts for your 2009 Subaru Forester-Rack boots

2009 Subaru Forester rack boots — what they do and how to look after them

Rack boots are absolutely used on the 2009 Subaru Forester (SH). Technical sources including the Subaru Forester (SH, MY2009) Service Manual – Steering System, Subaru FAST/Genuine Parts catalogues (which list the steering gear bellows on both sides), and common aftermarket fitment guides all specify protective bellows—commonly called rack boots—fitted to the rack-and-pinion steering. These bellows seal the inner tie rods and rack ends from grit and water, and are considered a service item if damaged.

On a 2009 Forester, each side of the steering rack is covered by a flexible boot that keeps out dust, mud, and road splash while allowing the rack to move freely. The boots protect the rack seals and inner tie rod joints from contamination that can quickly chew out the steering gear. In Aussie and Kiwi conditions—coastal air, corrugations, red dust—intact boots are a quiet hero for long rack life.

As part of routine servicing, it’s smart to inspect the rack boots every 10,000–15,000 km or at each oil change. Look for splits, perished rubber, loose or missing clamps, or fluid inside the boot (a hint the rack seals may be weeping). If a boot is torn, replace it promptly to avoid dirt getting in and steering fluid getting out. Genuine or quality aftermarket boots should be a snug fit and include proper clamps.

Replacement is straightforward for a trained tech and doesn’t require opening the hydraulic system. It does, however, disturb toe settings, so a wheel alignment is recommended afterwards. While there, it’s good practice to check the inner tie rod for play, the outer tie rod end, and ensure any boot vent path isn’t blocked so the bellows can breathe as the rack travels.

• Typical service checks: cracks, oil contamination, clamp condition, and boot movement with full steering lock.
• Good workshop tips: mark the tie-rod position before removal, use the correct ear/Oetiker-style clamps, avoid twisting the boot, and finish with a proper alignment.
• If fluid is found in a boot, plan for further diagnosis of the rack seals and power steering system.

Keeping the rack boots in top nick helps the Forester steer precisely, protects the rack from costly damage, and keeps the tyres wearing evenly.

Popular questions about 2009 Subaru Forester rack boots

How often should rack boots be replaced?
There’s no fixed interval, they’re replaced on condition. If a boot shows splits, is hard and cracked, or the clamps are loose, it’s time. Checking them at every service (around 10,000–15,000 km) is a solid plan, especially if the vehicle sees gravel or off‑road use.

Do I need a wheel alignment after changing a rack boot?
Yes, a wheel alignment is recommended. Swapping a boot usually means removing the outer tie rod end, which can alter toe. An alignment ensures straight tracking and even tyre wear.

Is it safe to drive with a torn rack boot?
It’s not ideal. A torn boot lets water and grit into the inner tie rod and rack, accelerating wear and potentially leading to leaks or notchy steering. It’s best to sort it promptly to avoid bigger bills down the track.
