Parts for your 2016 Subaru Impreza-Rack boots

2016 Subaru Impreza rack boots: what they do and when to replace them

Technical sources confirm the 2016 Subaru Impreza does use rack boots. The Subaru Service Manual (STIS) for the GP/GJ chassis shows bellows-style “steering gear boots” on both ends of the electric power steering rack, and Subaru’s Electronic Parts Catalogue lists “Boot – Steering Gear” as a serviceable item on MY2016 Impreza variants. Major aftermarket parts catalogues also carry direct-fit steering rack boots for this model. So rack boots are relevant to the 2016 Impreza.

On this Impreza, the rack boots (also called steering rack bellows) are the ribbed rubber sleeves at each end of the steering rack. Their job is simple but critical: they seal out water, dust and road grit while letting the inner tie rods move smoothly. Even though the 2016 model uses electric power steering, it still relies on a rack-and-pinion with tie rods, and it still needs boots to protect those moving parts.

As part of routine servicing, it makes sense to eyeball the boots from lock to lock. Under the bonnet or from beneath with the wheels turned, look for splits, perishing, oil/grease contamination and missing or loose clamps. Small cracks quickly turn into tears, and once they’re open, grit gets in and can chew out the inner tie rod and rack bushes, leading to play in the steering and uneven tyre wear.

If a boot is damaged, replacement is straightforward workshop fare but does involve disturbing the tie rod end. Mark the tie rod threads before removal to help preserve toe, fit the new boot with the correct orientation and proper clamps (not cable ties), then torque everything to spec. A wheel alignment is strongly recommended afterwards, even if the threads were counted. On the electric rack there’s no hydraulic fluid to leak, but a torn boot can still let water pool and corrode the rack bar—so don’t put it off.

Good practice for 2016 Impreza owners is to have the rack boots inspected at each service or WOF/roadworthy check, and sooner if there’s a knock over bumps or wandering on the motorway. When one side fails, replacing both boots as a pair helps keep wear even. Quality OEM-equivalent rubber lasts longer, and a light smear of appropriate grease on the inner tie rod ball joint (not inside the boot cavity) can help longevity.

• Common signs it’s time: visible cracks or tears, damp grit inside the boot, steering play or clunks, and rapid inner/outer tyre wear.
• After replacement: re-check clamp seating after a few hundred kilometres and book in an alignment.

Do electric power steering Imprezas still have rack boots?

Yes. The 2016 Impreza’s electric power steering keeps the same basic rack-and-pinion layout, with inner and outer tie rods that slide and pivot. The bellows boots protect those components from the elements, just as on a hydraulic system.

What are the signs a rack boot needs replacing on a 2016 Impreza?

Cracks, splits or oily grime inside the boot area are the big giveaways. Owners may also notice a light knock over bumps, vague steering feel, or uneven tyre wear. If a clamp has gone missing, the boot can walk off its seat and let dirt in.

Do you need a wheel alignment after replacing a rack boot?

Usually, yes. Even if the tie rod end is counted back to the same position, tiny differences can alter toe. An alignment protects tyres and ensures the Impreza tracks straight and feels right on the road.
