Parts for your 2020 Subaru Impreza-Rack boots

2020 Subaru Impreza Rack Boots

Referencing technical sources, the 2020 Subaru Impreza is fitted with steering rack boots. The Subaru factory service manual (STIS) for the GK/GT Impreza platform specifies bellows-type boots on both ends of the rack-and-pinion electric power steering assembly, and the Subaru genuine parts catalogue for MY2017–2023 Impreza lists “steering gear boot/bellows” and matching clamps as service parts. So, yes—rack boots are relevant, present and serviceable on this model.

On a 2020 Impreza, the rack boots (also called bellows or gaiters) are the flexible rubber sleeves that seal and protect the ends of the steering rack and the inner tie rods. Even though the car uses electric power steering (so there’s no hydraulic fluid at the rack), those boots are vital: they keep grit, water and road splash out, help retain the correct grease at the inner tie-rod ball joints, and shield the rack seals and polished surfaces from corrosion. If a boot splits, contaminants get in, which can chew out inner tie rods, damage rack seals and, over time, lead to a costly steering rack replacement.

As part of routine servicing, it’s smart to check both boots every 10,000–15,000 km or 6–12 months (typical AU/NZ service cadence). Look for cracks, perishing, grease flung onto the subframe, or damp dirt stuck around the boot folds. After gravel road work, beach runs, or floodwater encounters, inspect sooner—salt and silt are tough on rubber.

If a boot is torn, replace it promptly. Best practice is to use quality EPDM boots and new OE-style clamps rather than cable ties. Don’t pack the boot with grease, only lubricate the inner tie-rod ball joint per the service manual. The job usually involves removing the outer tie rod end, so plan for a wheel alignment afterwards. A good tech will mark thread positions to keep toe close, but an alignment is still recommended to keep tyres wearing evenly and steering tracking straight.

Rack boots are inexpensive compared to the steering rack they protect. Replacing a damaged boot early can save a heap by preventing water ingress and rust on the rack bar. If one side has failed from age, give the other side a hard look—rubber often ages in pairs.

• Inspect at each service for splits, perishing or grease sling.
• Replace damaged boots with new clamps, avoid reusing stretched bands.
• Torque inner/outer tie rods to spec and book an alignment afterwards.

FAQs

Does the 2020 Subaru Impreza have steering rack boots?
Yes. The Subaru service manual for the GK/GT Impreza and the Subaru parts catalogue both show bellows-style boots on each end of the electric power steering rack. They protect the inner tie rods and rack from dirt and water.

How often should the rack boots be checked or replaced?
Have them inspected at every routine service (about every 10,000–15,000 km or annually). Replace any boot that’s cracked, perished or torn, or if there’s evidence of grease being flung out. There’s no fixed time replacement—condition is the guide.

Do I need a wheel alignment after replacing a rack boot?
Usually, yes. Replacing a boot typically means removing the outer tie rod end. Even if the threads are marked, a post-repair alignment is recommended to ensure proper toe, straight steering and even tyre wear.
