2021 Toyota Land Cruiser steering-bushes: what they do and when to replace them

For the 2021 Toyota Land Cruiser (300 Series), steering-bushes are absolutely relevant and used. Toyota’s Electronic Parts Catalogue for the J300 lists rubber “bush, steering gear” isolators that mount the electric power steering (EPS) rack to the front crossmember, and the Toyota workshop repair manual illustrates inspection and replacement during steering gear installation. There’s no idler arm or centre link on this model (unlike older 80/100 series setups), so the rack-mount bushes are the key service items affecting steering feel and NVH.

On this Land Cruiser, the steering-bushes support and locate the EPS rack so it stays perfectly aligned while absorbing vibration and harshness from corrugations, ruts and city potholes. They help keep the wheel straight-ahead feel taut, reduce kickback, and stop the rack shifting under load. When they start to perish or compress, the driver can feel more play on-centre, a dull clunk over bumps, or a vague, “wandery” front end—especially noticeable on long Kiwi or Aussie highway runs with a loaded roof rack or towing.

Servicing-wise, these bushes aren’t a fixed-interval replacement. Toyota guidance is to inspect during front suspension and steering checks, and to replace if cracked, oil-soaked, deformed or loose in the brackets. For vehicles doing frequent gravel or outback work, it’s smart to have them checked every 40,000–60,000 kilometres or at least every second service. Genuine-style rubber preserves factory NVH, while some aftermarket polyurethane options trade a firmer feel for a touch more road noise—choose based on how the vehicle’s used.

Good workshop practice includes:

• Road test for clunks, steering shimmy and on-centre looseness.
• Visual inspection of rack mounts for splits, compression or movement under steering input.
• Check adjacent items: lower control arm bushes, sway bar links and tie rod ends.
• Replace bushes in pairs and perform a wheel alignment afterwards.

Because the LC300 uses EPS, care is needed not to lever against the motor housing when removing the rack or bushes. After refit, a steering angle calibration may be required if the rack has been disturbed. Kept in good nick, quality steering-bushes protect tyres, sharpen response and keep the big Cruiser tracking straight from beach access to back-country trails.

Popular questions

Do 2021 Land Cruisers have steering-bushes like older models?
Yes, but the setup’s different. The LC300 runs an electric power steering rack mounted with rubber bushes to the crossmember. There’s no idler arm or centre link, so no idler arm bushes as found on some older Land Cruisers. The rack-mount bushes are the ones that matter for feel and durability.

How often should the steering-bushes be replaced?
There’s no set interval. Have them inspected during routine servicing and after heavy off-road trips. High kilometre touring, corrugations and big tyres can accelerate wear. Replace when cracked, crushed, oil-soaked or if there’s movement at the rack mounts.

Can worn steering-bushes cause tyre wear or alignment issues?
They can. If the rack shifts under load, toe can change while driving, which leads to feathered tyres, tramlining and a nervous feel. After bush replacement, a proper wheel alignment helps lock in straight, predictable steering and even tyre wear.
