Parts for your 2022 Subaru Outback-Rack boots

2022 Subaru Outback rack boots: what they do and how to look after them

Yes, the 2022 Subaru Outback is fitted with rack boots. Technical references that show this include the Subaru Service Manual for MY22 Outback (Steering/EPS – Rack and Pinion section) and the Subaru Genuine Parts Catalogue (Group 34: Steering, “Steering Gear & Linkage” diagram), both of which identify flexible bellows-style “rack boots” on each end of the steering rack to cover the inner tie rods. Subaru’s scheduled maintenance also calls for periodic inspection of steering joints and boots during routine services.

On a 2022 Outback, the rack boots are the concertina rubber bellows on either side of the electric power steering rack. Their job is simple but critical: they seal out water, mud, and road grit, and they help keep grease around the inner tie rod joints. Because the Outback uses rack‑assist electric power steering (no hydraulic fluid), there’s no power‑steering oil inside these boots, but a split boot will still let contaminants in, which can chew out the inner tie rod and the rack’s end seals over time.

As part of regular servicing (every 12 months/15,000 km or sooner for heavy use), it’s smart to have the boots checked under the bonnet and on a hoist. Look for perishing, cracks at the folds, loose or missing clamps, or any signs of grit or water ingress. If a boot is torn, replace it promptly, leaving it will usually cost far more in steering gear wear.

Replacement is a straightforward job for a workshop: the outer tie rod end is removed, the old clamps and boot come off, the new boot slides on with the correct orientation, and OEM‑style clamps are crimped so they seal properly. It’s good practice to assess the inner tie rod for play while everything’s apart and renew it if there’s any looseness. Because toe can shift when the tie rod is disturbed, a wheel alignment should follow the repair to keep tyres wearing evenly and the Outback tracking straight.

Owners who tour gravel roads, tow, or regularly see beach or alpine conditions should have the boots inspected more often. If a boot looks wet, remember this model doesn’t use steering fluid, the moisture is likely water, road grime, or another vehicle fluid nearby. Keeping the rack boots intact is cheap insurance for the steering gear and helps the Outback feel tight and precise on Aussie and Kiwi roads.

• Common signs of trouble: split rubber, missing clamps, grit under the boot, or knocking/looseness over bumps.
• Always use quality OEM‑equivalent boots and proper crimp clamps, cable ties aren’t a lasting fix.
• Follow up with a wheel alignment after replacement.

Popular questions

How often should rack boots be checked on a 2022 Subaru Outback?
They should be inspected at every scheduled service (about every 12 months/15,000 km), or sooner if the vehicle sees rough roads, mud, or beach work. A quick look during a tyre rotation is also worthwhile to catch small splits before they become bigger problems.

What happens if a rack boot is torn and I keep driving?
A torn boot lets water and grit into the inner tie rod area, accelerating wear and potentially damaging the rack end seals. The steering can develop play and noise, and repair costs rise quickly. Replacing a boot promptly and aligning the front end is far cheaper than needing a rack assembly.

Do I need a wheel alignment after replacing a rack boot?
Yes, it’s recommended. Even if the tie rod locknut is marked, tiny changes can alter toe settings. An alignment protects tyre life and keeps the Outback driving straight.
