Parts for your 2009 Subaru Legacy-Rack boots

2009 Subaru Legacy rack-boots: what they do and when to replace them

Rack-boots (also called steering rack bellows or gaiters) are absolutely fitted to the 2009 Subaru Legacy. This is confirmed by Subaru’s Factory Service Manual for Legacy/Outback MY05–MY09 in the Steering—Rack and Pinion section, which details inspection and replacement of the steering gear boot and clamps, and by aftermarket service literature such as the Haynes Subaru Legacy & Outback 2000–2009 manual that includes procedures for replacing steering rack gaiters. Genuine Subaru electronic parts catalogues for BL/BP-chassis Legacy models also list “Boot – Steering Gear” for both left and right sides, reinforcing that the part is standard equipment.

On a 2009 Subaru Legacy, the rack-boots sit at each end of the steering rack, flexing as the inner tie-rods move. Their job is simple but vital: they keep dust, water and road grit out of the rack-and-pinion and inner tie-rod joints, and help retain the right environment for the joints to last. If a boot splits, grit can chew out the inner tie-rod ball joint and even the rack seals, which can lead to play in the steering, shudder, and power-steering fluid leaks. It’s also a likely WOF/RWC fail in NZ or Australia.

As part of routine servicing, it’s smart to give the rack-boots a quick look whenever the vehicle is on a hoist—especially if it sees gravel roads or beach drives. Light surface grime is normal, but any cracks, tears, missing clamps, or wetness inside the boot are red flags. Oil inside a boot often hints at an internal rack seal leak, not just a dodgy boot.

• Tell-tale signs: visible splits, perishing, loose/broken clamps, clicking on lock, uneven tyre wear from toe changes, or oily residue inside the boot.
• Replacement tips: remove the tie-rod end, slide off the old boot, lightly lubricate the new boot lip, and fit OEM-style crimp bands rather than cable ties. If the rack uses a breather or balance tube, keep it correctly routed.
• Alignment: because the tie-rod end is disturbed, a wheel alignment is recommended straight after boot replacement.
• Quality matters: use quality rubber boots sized for the Legacy’s rack—cheap, thin bellows don’t last long in Aussie or Kiwi conditions.

Left and right boots are usually mirror parts, replace them as a pair if one has failed. A careful DIYer can handle the job with basic tools, but if there’s any sign of internal fluid in the boot or play in the inner tie-rod, it’s worth having a technician assess the rack before simply fitting new bellows.

Popular questions about 2009 Subaru Legacy rack-boots

What are the most common signs a rack-boot is failing?
Cracks, splits, or a boot that’s gone hard and perished are the big giveaways. Grease or fluid inside the boot, loose or missing clamps, and new steering play or knocking on rough roads also point to trouble. If the boot has torn for a while, you may notice uneven tyre wear from toe changes.

Can they drive with a torn rack-boot?
It’ll usually steer, but it’s not a good idea. A torn boot lets in water and grit that can quickly wear out the inner tie-rod and rack seals. That can turn a simple boot job into a full rack replacement. It may also fail a WOF/RWC, so replacement should be booked promptly.

Do you need a wheel alignment after replacing rack-boots?
Yes, best practice is to do an alignment. Even if the tie-rod end is counted back on, tiny differences add up. An alignment resets toe to spec, protects tyres, and ensures the Legacy tracks straight.
