Parts for your 2006 Toyota Land cruiser-Steering bushes

2006 Toyota LandCruiser steering bushes — what they do and when to change them

Based on technical sources, steering bushes are relevant and fitted on the 2006 Toyota LandCruiser. Toyota’s chassis/steering service manuals for the 100/105 Series (Steering section) and the Toyota Electronic Parts Catalogue list either steering rack mounting bushes on independent front suspension (UZJ100/HDJ100) models or idler arm/relay rod bushes on solid-axle (HZJ105/FZJ105) models. Major aftermarket catalogues used across Australia and New Zealand (e.g., SuperPro, Nolathane, Whiteline) also publish dedicated bush kits for 1998–2007 LandCruiser 100/105, confirming fitment and serviceability.

On this LandCruiser, steering bushes keep the steering gear properly located while isolating vibration and road shock. In IFS models they cradle the steering rack, in solid-axle models they support the idler arm and related linkages. When these bushes wear, the steering gear can shift under load, causing vague steering, clunks over corrugations, and shimmy. Keeping them healthy preserves steering precision, reduces NVH, and helps tyres wear evenly — pretty important whether it’s towing a van or tackling the Birdsville Track.

Servicing advice for a 2006 LandCruiser is straightforward. Factory-style rubber bushes give OE ride comfort, while quality polyurethane options sharpen response and last longer off-road. Either way, replacement should be done with the vehicle at normal ride height so the bushes aren’t preloaded. After any steering bush replacement, a wheel alignment is smart practice. It’s also a good time to inspect inner/outer tie-rod ends, rack ends or relay rod joints, the idler arm pivot (105), and steering rack mounting bolts (100 IFS).

• Typical signs the bushes are due: vague on‑centre feel, steering knock over potholes, wandering on cambered roads, shimmy at certain speeds, and uneven front tyre wear.
• Inspection rhythm: every 20,000–30,000 km if it lives on corrugations or carries a bull bar and big tyres, otherwise, check at regular services.
• Fitment tips: use correct lube for polyurethane sleeves, torque fasteners to spec with the vehicle settled on its wheels, and avoid petroleum-based cleaners on rubber.

For owners of the solid‑axle 105, don’t ignore the idler arm pivot and relay rod bushes — a little slop there multiplies at the steering wheel. For IFS 100 owners, fresh rack mounts often make the front end feel tighter than it has in years.

FAQs

How can someone tell if their 2006 LandCruiser’s steering bushes are worn?
Common giveaways are a dull knock through the floor over sharp bumps, tramlining or wander at highway speeds, and a steering wheel that feels loose on centre. With the front raised safely, levering the rack or idler arm while watching for bushing movement is a simple workshop check.

Rubber or polyurethane — which suits a 2006 LandCruiser best?
OE-style rubber keeps the plush factory feel and minimises noise. Polyurethane typically lasts longer on corrugations and firms up steering response, which many touring and towing owners prefer. Quality brand and correct installation matter more than colour — either can work brilliantly when fitted right.

Is a wheel alignment needed after replacing steering bushes?
Yes, it’s recommended. Even if toe hasn’t been adjusted directly, changing bush compliance can shift the rack or linkage position slightly. An alignment helps lock in straight-ahead feel and protect those pricey all-terrains.
