Parts for your 2006 Subaru Impreza-Rack boots

2006 Subaru Impreza rack-boots: purpose and service advice

Rack-boots are used on the 2006 Subaru Impreza. The Subaru Factory Service Manual (2006 Impreza, Steering section) and the Subaru Genuine Parts Catalogue both list left and right steering rack bellows (commonly called rack-boots) fitted over the inner tie rods on the rack-and-pinion assembly. Aftermarket fitment catalogues for the 2002–2007 GD/GG platform also specify direct-replacement rack-boots, confirming they’re standard kit on this model.

On a 2006 Impreza, the rack-boots are there to keep grit, water, and road splash out of the steering rack while holding the correct grease around the inner tie rod joints. They act like flexible dust covers, allowing the rack to move while sealing the vulnerable bits. When a boot cracks or splits, contaminants work their way in and the rack can wear quickly, leading to notchy steering, inner tie rod play, and potentially a pricey rack rebuild. In AU/NZ, a torn boot can also be a WOF/reg/roadworthy fail.

Good servicing habits go a long way. During routine services, have the technician:

• Inspect both boots for cracks, perishing, or oil/grease weep
• Check clamps are tight and correctly positioned
• Squeeze the boot gently to feel for fluid — power steering fluid inside suggests an internal rack seal leak

Replacement is straightforward but best done properly. It’s wise to replace boots in pairs and use OE-style clamps rather than cable ties. The job involves removing the outer tie rod end, sliding the old boot off, cleaning the area, then fitting the new boot with the correct orientation. Mark the tie rod threads or measure lengths before disassembly so the toe isn’t wildly out for the drive to the alignment shop. A wheel alignment is recommended afterwards. While there, check inner and outer tie rod ends for play and renew if needed. Use quality EPDM/neoprene boots suited to heat and oil exposure, and apply the light grease specified by Subaru inside the boot pleats.

Signs it’s time to act include visible splits, flung grease on the subframe, uneven steering feel, or dampness inside the boot. Regular checks every service (around 10,000–15,000 km) help prevent steering rack damage and keep the Impreza steering sharp and compliant.

• Tip: If a boot has fluid inside, the rack’s internal seal may be leaking — replacing the boot alone won’t fix the root cause.

Popular questions

How often should rack-boots be replaced on a 2006 Subaru Impreza?
They don’t have a fixed interval, they’re replaced on condition. Inspect them at each service. If you see cracking, perishing, loose clamps, or contamination inside, fit new boots straight away. Many last years in normal use, but heat, age, and off-road grime can shorten their life.

Do I need a wheel alignment after replacing the rack-boots?
Yes, it’s recommended. Even if you carefully mark threads, minor changes to the tie rod position can alter toe. A proper alignment protects tyres, keeps the steering centred, and ensures the Impreza tracks true.

What happens if I drive with a split rack-boot?
Dirt and water can get into the rack and inner tie rod joint, accelerating wear. That can lead to steering play, noise, and ultimately a leaking or damaged rack. It can also attract a WOF/roadworthy fail in AU/NZ. It’s best to sort it promptly.
