Parts for your 2003 Subaru Forester-Rack boots

2003 Subaru Forester rack-boots: what they do and when to replace them

Yes, rack-boots are absolutely used on the 2003 Subaru Forester. Technical references including the Subaru Forester (SG, 2003 MY) Service Manual – Steering System section, Subaru parts catalogues listing “steering gear boot/bellows” on both sides, and major aftermarket catalogues for SG Forester confirm the presence of rack-and-pinion steering with protective bellows boots at each end of the rack. So this model does rely on rack-boots for proper steering protection and performance.

On a 2003 Forester, the rack-boots (also called bellows or gaiters) are flexible sleeves that seal the ends of the steering rack and cover the inner tie rods. Their job is to keep water, dust, and road grit out of the rack’s moving parts and seals, while allowing the steering to travel freely from lock to lock. Healthy boots help the rack last longer, maintain smooth steering feel, and keep power steering fluid and lubricant where they belong. Torn boots can quickly lead to corrosion and worn rack seals, which often turns into an oily mess inside the boot and, eventually, a leaky steering rack.

• Common signs it’s time for new rack-boots:
  • Visible splits or perishing in the rubber
  • Grease or oil flung around the inner guard or subframe
  • Play, stiffness, or notchy steering feel
  • WoF/rego inspection fail due to damaged steering dust covers

As part of routine servicing on a 2003 Forester, it’s smart to inspect the rack-boots every service interval (or at least every 10,000–15,000 km). Replace them if cracked, swollen, or torn. When fitting new boots, use quality OE-style clamps, reconnect any breather/equaliser tube between the boots if equipped, and avoid packing the boot with excess grease—only a light smear where specified by the manual. If fluid is found inside a boot, that’s a red flag for internal rack seal leakage and the rack may need repair or replacement.

Replacing a boot typically involves removing the tie-rod end, sliding off the old boot, cleaning the area, and installing the new one with fresh clamps. Mark the tie-rod end position or count the turns to help preserve toe, but a proper wheel alignment afterwards is strongly recommended. With care, it’s a straightforward job for a competent home mechanic with axle stands and the right spanners, or a quick turnaround for a workshop. Keeping those boots in good nick helps the Forester steer sweetly and avoids pricey rack issues down the track.

Do all 2003 Subaru Foresters have rack-boots?
Yes. All 2003 Forester variants (SG series) use a rack-and-pinion steering gear that relies on protective rack-boots on both sides. The design is consistent across petrol models, manual and auto alike, as shown in Subaru’s service literature and parts catalogues.

They’re a core component of the steering assembly, so inspection and timely replacement are part of normal maintenance for any SG Forester.

Is it safe to drive with a torn rack-boot?
Not ideal. A split boot lets water and grit in, which can chew out inner tie rods and rack seals. That often turns a cheap boot job into an expensive rack overhaul. In NZ and many Aussie states, a torn steering dust cover can also lead to a WoF/roadworthy fail.

If a boot is torn, replace it promptly and check for fluid inside the boot—if present, the rack may already be leaking and need further attention.

Do you need a wheel alignment after fitting rack-boots?
Usually yes. Changing a boot means disturbing the tie-rod end. Even if the threads are marked or the turns are counted, small differences can nudge toe out of spec.

Book a proper wheel alignment after the job to protect tyres and ensure the Forester tracks straight and steers as it should.
