Parts for your 2006 Toyota Land cruiser-Control arms

2006 Toyota Land Cruiser control arms — what they do and when to replace

Control arms are absolutely relevant on the 2006 Toyota Land Cruiser. Technical sources including the Toyota Repair Manual for the 100 Series (RM1149), the Toyota Electronic Parts Catalogue (Front Suspension, Group 48), and the Toyota New Car Features guide for the 100 Series confirm that 2006 IFS (independent front suspension) models like UZJ100/HDJ100 use double wishbones with upper and lower control arms. The 105 Series (live front axle) sold in some markets uses front radius arms and a panhard rod, while the rear on both 100 and 105 uses trailing arms — commonly referred to as rear control arms. So whether it’s the IFS front or the live-axle layout, “control arms” are very much part of the suspension package.

On IFS models, the front control arms locate the steering knuckle and let the suspension move up and down while keeping wheel alignment angles steady. They carry bushes at the chassis pivots and ball joints at the knuckle end, so they’re crucial for ride comfort, steering feel, and tyre life. At the rear, the trailing control arms keep the solid axle centred and stable under braking, towing, and off-road articulation.

As part of routine servicing on a 2006 Land Cruiser, it’s smart to inspect the control arms, bushes and ball joints every 20,000–30,000 km, or sooner if the vehicle works off-road, tows regularly, or runs heavier accessories. Bushes dry, crack and split over time, ball joints can develop play and split dust boots — any of which can knock alignment out and chew tyres.

• Common signs of wear: clunks over bumps, vague steering or pull, instability under brakes, uneven tyre wear, and visible bush cracking or leaking ball joint boots.
• Replacement tips: replace arms or bushes in axle pairs, torque pivot bolts at ride height, renew eccentric/cam bolts if seized, and always book a wheel alignment afterwards (camber/caster on the front depends on arm position).
• Parts choices: genuine-style rubber bushes ride quietly, high-quality aftermarket or polyurethane options can sharpen handling but may transmit more road feel. For 105 Series fronts, look to radius arm bushes rather than upper/lower arms.

Look after the control arms and the Cruiser will track straight, ride smoothly, and keep those tyres wearing nice and even — whether it’s commuting, touring, or heading bush.

Do all 2006 Land Cruisers have front upper and lower control arms?

IFS 100 Series models do — they use double wishbones with upper and lower control arms. The 105 Series (live front axle) doesn’t have wishbones, it runs radius arms and a panhard rod up front. All models use rear trailing control arms.

How often should control arm bushes and ball joints be replaced?

There’s no hard expiry, but many see replacement anywhere between 100,000 and 200,000 km depending on use. Inspect at each service, off-road work, towing, and corrugations accelerate wear. Replace if there’s play, torn boots, or cracked bushes.

Do I need a wheel alignment after replacing control arms?

Yes. Any front-end arm or bush work changes geometry, so a full alignment is essential. It locks in camber and caster on IFS models and protects tyre life and steering feel.
