Parts for your 2010 Subaru Forester-Rack boots

2010 Subaru Forester Rack-Boots

Based on the Subaru Forester SH (2009–2013) Service Manual steering section and the Subaru Electronic Parts Catalogue for the 2010 Forester, this model uses rack-and-pinion power steering with protective rack-boots (also called bellows or gaiters) on each side of the steering rack. Workshop procedures in the factory manual specifically describe inspecting and replacing the steering gearbox boots and clamps, confirming they’re a fitted, serviceable item on this vehicle.

On a 2010 Subaru Forester, the rack-boots do a deceptively big job. They seal and shield the moving inner tie rods and the rack bar from road grit, water, and stones, while also keeping the correct grease where it belongs. Because the SH Forester runs a hydraulic power-steering rack, a split boot can let contaminants in and trap moisture around the rack, which can accelerate wear on the inner tie rod joints and the rack itself. That’s why the factory service documentation calls for routine inspection and prompt replacement if there’s any damage.

As part of regular servicing, it’s smart to check both boots every 10,000–15,000 km or at each service visit. Look for cracks, splits in the bellows, perished rubber, missing or loose clamps, grease flung onto the control arm, or signs of power-steering fluid misting near the rack ends. If a boot is compromised, replace it straight away. Good practice is to renew both clamps and ensure the boot seats fully in its grooves, avoid twisting the boot when refitting, as that can shorten its life. If an inner tie rod is loose or has play, address that at the same time—there’s no point fitting a fresh boot over a worn joint.

Replacement is a straightforward workshop job but does involve removing the outer tie rod end, so a wheel alignment is recommended afterwards to dial toe back to spec. Clean the rack bar lands before sliding the new boot on, use the correct-style clamps rather than generic cable ties, and check the power-steering system for leaks while you’re there. Keeping the rack dry and clean pays off—healthy boots help the Forester steer precisely, protect the rack from expensive damage, and keep it compliant for roadworthy/WoF checks across Australia and New Zealand.

• Common signs a rack-boot needs attention: split bellows, grease on the strut/control arm, dirt inside the boot, clicking or knock over bumps, or a failed WoF/roadworthy.
• Tip: Choose quality boots designed for the SH Forester rack so clamp fit and bellows travel are spot on.

Popular questions about 2010 Subaru Forester rack-boots

How often should the rack-boots be inspected?
They should be checked at each service or at least every 10,000–15,000 km. The rubber lives close to road heat, grit, and UV, so catching small cracks early prevents moisture and dirt from getting onto the rack and inner tie rods.

Do I need a wheel alignment after replacing a rack-boot?
Yes, a wheel alignment is recommended. The job requires removing the outer tie rod end, and even if you count threads or mark positions, small variations can alter toe. An alignment keeps tyre wear and steering feel on point.

Can I keep driving with a torn rack-boot?
It’ll still steer, but it’s risky. A torn boot lets water and grit in, which can chew out the inner tie rod and rack seals, potentially leading to play, leaks, and an expensive rack rebuild. Replacing a boot early is far cheaper than replacing a rack.
