Parts for your 2007 Toyota Crown-Rack boots

2007 Toyota Crown rack boots — what they do and how to look after them

Yes, the 2007 Toyota Crown uses rack boots (also called steering rack bellows). This is confirmed by Toyota’s Electronic Parts Catalogue for the GRS18#/UZS18# series, which lists a “Boot, Steering Rack”, and by the Crown (S180) repair manual steering section that shows removal/installation of the rack boots on the rack-and-pinion steering gear. Any rack-and-pinion setup needs accordion-style boots to shield the inner tie rods and rack ends, so they’re absolutely relevant on this model.

Rack boots keep grit, water, and road splash out of the steering gear, and they help retain the correct lubrication around the inner tie-rod ball joints. On a hydraulic power-steering Crown, a torn boot can also trap leaking fluid from a failing rack seal, which is a handy clue something deeper needs attention. Leave a split boot too long and you risk rusty rack teeth, sloppy inner tie rods, and premature steering gear wear.

They’re simple but important, so it’s smart to check them at every service, WOF, or when chasing a front-end clunk. Look for:

• Cracks, splits, or perished rubber
• Loose or missing clamps
• Grease flung around the inner rim area
• Fluid pooled in the boot (often means a rack seal leak)

Replacing a boot isn’t a massive job, but care matters. Typically you’ll centre the steering, mark the tie-rod/locknut position, remove the outer tie-rod end, slide off the old boot and clamps, inspect the inner tie rod for play, then fit the new boot with fresh clamps. Use the correct grease as specified in Toyota literature, avoid twisting the boot, and make sure its vents aren’t pinched so it can compress/extend freely when steering. Because toe can change the moment you disturb the tie rod, book a wheel alignment straight after fitment—even if you carefully counted turns back to the locknut mark.

For parts, stick with quality OEM or equivalent. Toyota’s parts listings for the 2007 Crown identify a dedicated “Boot, Steering Rack” for the S180 chassis, exact part numbers vary by sub-model, so match by VIN. Fresh clamps are a must, and if one boot has failed, it’s sensible to check or replace the other side while you’re there. Keep the boots tidy and the steering gear will happily clock up the kilometres with no dramas.

Popular questions about 2007 Toyota Crown rack boots

Does the 2007 Toyota Crown definitely have rack boots?
Yes. Toyota’s S180 Crown repair manual covers rack boot removal/installation, and the Toyota EPC lists a “Boot, Steering Rack” for GRS18#/UZS18# models. They’re standard on its rack-and-pinion steering.

What are the common symptoms of a bad rack boot?
Visible splits or perishing, grease spray near the inner rim, loose clamps, dirt inside the bellows, or power-steering fluid pooling in the boot. You might also notice accelerated inner tie-rod wear or vague steering if contamination has got in.

Do I need a wheel alignment after replacing a rack boot?
Usually, yes. Even if you mark everything perfectly, disturbing the tie rod can nudge toe settings. A post-job alignment keeps tyre wear even and the Crown tracking straight.
