Parts for your 2021 Toyota Land cruiser-Rack boots

2021 Toyota LandCruiser rack boots: what they are and when to replace them

Based on Toyota technical literature and parts catalogues: the 2021 LandCruiser 200 (J200) and the new 300 Series (J300) use a rack-and-pinion steering gear with protective bellows on each end—commonly called rack boots. Toyota Repair Manual steering sections and the Toyota Electronic Parts Catalogue list these bellows/boots as service parts for J200/J300. By contrast, the 2021 LandCruiser 70 Series (VDJ76/78/79) runs a recirculating-ball steering box and linkages, so there’s no steering rack and therefore no rack boots on those models.

For owners of a 2021 LandCruiser 200 or 300 Series, rack boots do a deceptively simple but critical job. They seal the inner tie-rod joints and the ends of the steering rack, keeping dust, water, and grit out while holding grease in. Off-road work, corrugations, sand, and mud—exactly the stuff a Cruiser lives for—can shred lesser rubber. Healthy boots mean the rack and inner tie rods stay lubricated and protected, so steering stays precise and the power-steering system doesn’t cop premature wear.

Service-wise, it’s smart to have the rack boots checked at every scheduled service or tyre rotation—roughly every 10,000–15,000 kilometres in Aussie and Kiwi conditions. A quick visual under the front shows most of what matters. If a boot is cracked, torn, or oily with leaking grease, it needs sorting before the next big trip. Ignoring a split boot lets grit chew up the inner joint and can let water into the rack housing. That’s when a cheap boot job can snowball into an inner tie-rod or even rack replacement.

Replacement is straightforward for a trained tech: the tie-rod end is marked and removed, the damaged boot and clamps are swapped, fresh grease is applied to spec, and everything is reassembled. Because the outer tie-rod end comes off, a wheel alignment is recommended to keep tyre wear even and steering feel spot on. For vehicles with KDSS or height-adjustable suspension, a workshop that knows LandCruisers is worth its weight—they’ll follow the Toyota procedure so the steering wheel stays centred and assist feels factory.

• Tell-tale signs: cracked or perished rubber, visible splits, grease sling on the lower control arm, notchy or vague steering after water crossings.
• Good habits: rinse the underbody after beach work, avoid pressure-washing boots up close, and inspect after rocky tracks or deep ruts.
• Parts tip: use quality boots and clamps designed for the J200/J300 rack—universal bellows can kink or chafe at full lock.

Look after the rack boots and the steering will keep feeling tight, predictable, and ready for the next long haul across the Nullarbor or a wet weekend on the West Coast.

Popular questions about 2021 Toyota LandCruiser rack boots

How often should rack boots be inspected on a 2021 LandCruiser?

They should be checked at each service or tyre rotation, typically every 10,000–15,000 km. If the vehicle regularly sees beaches, fords, or dusty station roads, add a quick glance after big trips. Early detection of minor cracking saves the inner tie rods and rack from gritty damage.

What symptoms point to a torn rack boot?

Look for visible splits, grease sprayed on nearby suspension arms, or damp/oily residue around the inner tie rod. Steering that feels notchy after a water crossing can also be a clue. Address it promptly—grit plus lost grease can accelerate wear on the inner joint and rack seals.

Can it be driven with a damaged rack boot?

It’ll usually drive, but it’s not a great idea. A split boot lets in sand and water, which can quickly turn into inner tie-rod play, uneven tyre wear, and costly rack repairs. If a boot’s torn, book it in soon and plan on a wheel alignment after replacement.
