Parts for your 2017 Subaru Impreza-Rack boots

2017 Subaru Impreza rack boots — what they are and why they matter

Yes, the 2017 Subaru Impreza is fitted with steering rack boots (also called rack bellows or gaiters). This is confirmed in Subaru’s Factory Service Manual for the 2017MY Impreza (Steering section) and the Subaru FAST electronic parts catalogue for GK/GT chassis, which both show the rack-and-pinion assembly with protective boots and boot bands. Even though the Impreza uses electric power steering, the rack still has inner tie rods that rely on these boots for sealing and protection.

On this model, the rack boots act like flexible dust covers that keep grit, water, and road splash away from the rack bar and inner tie rod joints. They also help retain lubricant at the inner joints and prevent corrosion at the rack seals. When a boot splits, the steering gear can cop abrasive dirt, which speeds up wear and can lead to play in the steering, notchy feel, or even costly rack leaks.

• What they protect: rack bar, inner tie rod joints, rack seals.
• Signs they’re tired: visible cracks or tears, grease sling on the inside of the wheel, a wet/dirty inner tie rod, clicking or knocking over bumps, or a rubber boot that’s gone hard and brittle.

As part of regular servicing, a quick visual under the front of the car is well worth it. If a boot is torn, replace it promptly to avoid turning a cheap fix into a full rack replacement. Use quality boots and new boot bands, and avoid petroleum-based cleaners on the rubber. Many racks use a breather or crossover tube, if fitted, make sure it’s reconnected so pressure can equalise as the steering moves lock-to-lock.

Replacement usually involves lifting the front, removing the wheel, marking the outer tie rod position, disconnecting the tie rod end from the knuckle, sliding off the old boot, and fitting the new boot with the correct bands. Counting the tie rod turns helps keep toe close, but it’s smart to get a wheel alignment check afterwards. While in there, check the inner tie rods for axial play and the rack for free movement. If there’s water or grit inside the old boot, inspect the inner joint more closely and consider replacing it.

Plenty of owners choose OEM-style boots for OE fit and durability, but good aftermarket options are available. Either way, fresh, properly clamped boots are cheap insurance for long, quiet steering life on an Aussie or Kiwi commute.

FAQs

Does a 2017 Subaru Impreza actually have rack boots?
It does. The Subaru service manual and parts catalogue for the 2017MY Impreza (GK/GT) show rack bellows and boot bands on the electric-assisted rack-and-pinion. EPS doesn’t delete the boots, they still shield the inner tie rods and rack seals.

Is it safe to drive with a torn rack boot?
Short-term, you might not notice much, but a torn boot lets water and grit in, which can chew out the inner tie rod and rack seals. That’s how small tears become big steering bills. Best move is to replace the boot promptly and have the inner joint checked.

Will I need a wheel alignment after replacing rack boots?
If the outer tie rod is removed to slide the boot off, toe can shift. Counting turns helps, but a post-job alignment check is good practice to keep tyre wear tidy and steering straight.
