Parts for your 2005 Toyota Land cruiser-Rack boots

2005 Toyota Land Cruiser rack-boots: are they used on this model?

For the 2005 Toyota Land Cruiser (100 Series – UZJ100/HDJ100), rack-boots aren’t used because the vehicle doesn’t have a steering rack. Toyota’s technical information for the 100 Series shows a recirculating-ball power steering gearbox with a pitman arm, relay rod (drag link), idler arm and tie rods, rather than a rack-and-pinion setup. This is confirmed by Toyota’s Electronic Parts Catalogue (EPC) for UZJ100/HDJ100 and the factory Repair Manual (Steering, SR section), which list a “steering gear assembly” and tie-rod dust boots, but no “rack boots” or steering “rack” component. Popular workshop references in Australia and NZ (e.g., Gregory’s/Haynes manuals covering 100 Series) reflect the same design.

Why the difference? Heavy-duty wagons like the 100 Series were engineered for off-road durability and towing, where a recirculating-ball gearbox is robust and better resists shock loads. Rack-and-pinion systems (the ones that use rack-boots/bellows) are common on lighter vehicles and models like the Land Cruiser Prado 120, but not on the 2005 100 Series Land Cruiser.

What should owners look at instead of rack-boots? The steering and suspension on this Land Cruiser still rely on protective boots—just not on a steering rack. The key rubber components to inspect during servicing include:

• Tie-rod end dust boots (inner and outer)
• Idler arm bushes and seals, and pitman arm condition
• Upper and lower ball joint dust boots
• Front CV boots (if IFS-equipped)
• Power steering gearbox seals and hoses (watch for fluid weeps)

Routine checks every service or 10,000 km help avoid premature wear. Look for split or perished boots, grease sling, free play in steering (wander), uneven tyre wear, or power steering fluid leaks around the sector shaft. After off-road trips, hose off mud and grit that can sit against rubber boots and accelerate cracking. If any boot is torn, replace it promptly to keep contaminants out and preserve joint life. When reassembling, ensure correct torque and alignment, and follow Toyota’s spec from the 100 Series SR section for preload and free play checks on the steering gearbox.

Bottom line: on a 2005 Land Cruiser 100 Series, “rack-boots” aren’t applicable. Focus maintenance on the gearbox, linkages and the various dust boots that actually protect the steering and suspension joints.

Popular questions about 2005 Toyota Land Cruiser rack-boots

Do 2005 Land Cruisers have rack-boots?
No. The 100 Series uses a recirculating-ball steering gearbox, not a rack-and-pinion. That means there’s no steering rack and no rack-boots to replace. Instead, it relies on tie-rod end dust boots and other protective boots throughout the front end.

What steering boots should be checked on a 2005 Land Cruiser?
Owners should inspect tie-rod end dust boots, ball joint boots, and the idler arm area, plus the power steering gearbox for leaks. If independent front suspension is fitted, keep an eye on CV boots as well. Any split or leaking boot is a sign to replace it before grit destroys the joint.

Why do some Toyotas have rack-boots and others don’t?
Vehicles with rack-and-pinion steering use bellows-style rack-boots to keep dirt out of the rack. The 2005 Land Cruiser 100 Series uses a steering gearbox designed for heavy-duty use, so it doesn’t need rack-boots. Models like the Prado (120 Series) do have rack-and-pinion and therefore use rack-boots.
