Parts for your 2010 Subaru Exiga-Rack boots

2010 Subaru Exiga rack-boots: what they do and when to replace them

Yes, the 2010 Subaru Exiga uses rack-boots. Subaru’s own technical literature confirms it: the Exiga YA-series runs a hydraulic, rack-and-pinion steering gear, and the steering rack is sealed at each end by bellows-type rack-boots (also called steering rack bellows). The Subaru Exiga Service Manual (Steering/Power Steering – Rack and Pinion) specifies inspection of the rack boots, and the Subaru FAST parts catalogue for MY2010 lists left- and right-hand “Boot – Steering Gear” with matching clamps and clips. That makes rack-boots a relevant, serviceable item on this model.

On the Exiga, the rack-boots keep dust, water, and road grit out of the inner tie rod joints and the rack bar, while helping contain grease where it belongs. When they split or the clamps loosen off, contaminants can chew out the inner joint and even allow power steering fluid to track into the boot—both of which can escalate into vague steering, clunks, and premature rack wear.

As part of routine servicing, it’s smart to eyeball the boots every 10,000–15,000 km or at each oil change. Look for cracks at the folds, perishing, loose or missing clamps, and any oily residue inside or weeping out of the boot. Oily fluid suggests an internal rack seal issue rather than just a torn boot.

If a boot is damaged, replace it promptly. On the Exiga, that job typically means removing the outer tie-rod end from the knuckle, sliding the old boot off, cleaning the rack area, fitting the new boot in the correct orientation, and securing fresh clamps. Because the tie-rod end is disturbed, a wheel alignment is recommended straight after. Where one boot has failed from age, doing both sides together is often the most cost-effective move.

Tips for longer life:

• Keep an eye on clamp tension after rough-road use.
• Avoid blasting the boots directly with a pressure washer.
• If driving through floodwater, check the boots soon after for trapped silt or moisture.

When genuine Subaru parts or quality equivalents are used, new boots should give years of service. If there’s play in the inner tie rod or evidence of fluid inside the boot, it’s worth assessing the inner joint or the steering rack itself at the same time to save double labour.

Popular questions about 2010 Subaru Exiga rack-boots

How often should the rack-boots be checked?
They should be inspected at each regular service or roughly every 10,000–15,000 km. The check is quick: look for splits, perishing, loose clamps, or any oil inside the boot. Catching a crack early can prevent inner tie-rod and rack wear.

What are the signs a rack-boot has failed?
Common signs include visible splits, grease flung around the inner guard, sand or grit caught in the folds, or a light steering clunk over bumps. If you see power steering fluid inside the boot, that points to an internal rack seal issue rather than just the boot.

Do I need a wheel alignment after replacing rack-boots?
Yes. Replacing a boot usually means removing the outer tie-rod end, which can alter toe settings. A proper alignment ensures the Exiga tracks straight and preserves tyre life.
