Parts for your 2020 Subaru Outback-Rack boots

2020 Subaru Outback rack boots — what they do and how to look after them

Rack boots are absolutely used on the 2020 Subaru Outback. Subaru’s own technical literature backs that up: the steering section of the Subaru Technical Information System (STIS) shows a rack-and-pinion layout with protective bellows at each end of the rack, and the official Subaru parts catalogue lists steering gear boots/bellows as serviceable items for the MY20 Outback. Even though this generation runs electric power steering (EPS) rather than a hydraulic pump, the rack still needs flexible dust boots to keep the moving bits clean and protected.

On the 2020 Outback, the rack boots (also called bellows) slip over the inner tie rods and the ends of the steering rack. Their job is simple but critical: keep grit, water, and road grime away from the polished rack shaft and inner tie rod joints, while letting the steering move freely from lock to lock. They also help retain the correct grease around the inner joints. If a boot splits, the inner tie rod and rack can cop dirt and moisture, which can chew out the joint, cause corrosion, and make the steering feel rough or notchy. With EPS there’s no power steering fluid to leak, but contamination damage can still get pricey fast.

• Visible splits, tears, or perishing in the rubber
• Wet, muddy, or greasy buildup around the inner tie rod area
• Clicking or clunking over bumps or when turning
• Stiff or inconsistent steering feel
• Uneven front tyre wear tied to toe changes

There’s no set replacement interval for rack boots on the 2020 Outback, so the smart play is to have them inspected at every scheduled service. For Australia and New Zealand, that’s typically every 12 months (or around 12,500–15,000 km, depending on the plan). If a boot’s torn, replace it promptly to protect the rack. A proper job means removing the outer tie rod end, sliding on a quality boot, and securing new clamps. Because toe can change when the tie rod is disturbed, a wheel alignment is recommended straight after. If the vehicle sees gravel roads, beach launches, or water crossings, keep an even closer eye on the boots and consider replacing both sides as a pair when one fails.

Does the 2020 Subaru Outback have rack boots?

Yes. The MY20 Outback uses a rack-and-pinion steering system with electric assist, and it’s fitted with bellows-style rack boots on both sides. Subaru’s service manual and genuine parts catalogue both include these boots for this model.

How often should rack boots be checked or replaced?

Check them at every routine service. There’s no fixed replacement interval—swap them out any time a boot shows cracking, perishing, or a split. Vehicles that spend time on gravel, in mud, or around salt water should be checked more often.

Do you need a wheel alignment after replacing rack boots?

Usually, yes. Replacing a boot normally involves removing the outer tie rod end, which can alter toe. A post-repair alignment makes sure the Outback tracks straight and protects tyre life.
